Japan Techniques

The Japanese bento (弁当) — a portioned meal packed in a compartmented box — has evolved from practical field rations into one of the most elaborately considered expressions of food culture in the world. The makunouchi bento (幕の内弁当, 'between-acts bento') dates to Edo-period kabuki theatre intervals: rice, pickles, and small savoury dishes arranged to be eaten efficiently during the break. The form migrated to train stations (ekiben, 駅弁) where regional specialties packed in distinctive boxes became travel attractions in themselves — the Masuzushi trout-pressed sushi of Toyama, the cow-shaped container of Yonezawa gyuniku bento, the crab bento of Hokkaido. Modern home bento culture centres on the art of packing nutritionally balanced, visually attractive, appropriately portioned meals — typically for children or partners. Kyaraben (character bento) extends this into elaborate miniature tableaux of cartoon characters assembled from food. The bento aesthetic principles — colour contrast, compartmentalisation, seasonal ingredients, visual balance — express core Japanese aesthetic values applied to everyday nourishment.

Buta no kakuni is Japan's definitive braised pork belly dish — pork braised until it is trembling, almost liquid in its gelatinous fat layers and deeply lacquered with a soy-mirin reduction. The Nagasaki version carries a specific historical distinction: it is the iteration most directly influenced by the dish's Chinese antecedent, hong shao rou, which arrived in Nagasaki through the Dutch and Chinese trading communities during the Edo period when the city was Japan's sole international port. The Nagasaki kakuni traditionally incorporates awamori — the distilled Okinawan rice spirit — in the braising liquid alongside soy, mirin, and sake. This is not universally replicated across Japan, where sake alone is standard, but in the Nagasaki and southern Japan context, awamori's lower sweetness and distinct character adds a subtle complexity that differentiates it from mainland versions. The dish also appears in association with the shippoku cuisine of Nagasaki, a hybrid Chinese-Japanese-Dutch banquet tradition that is the historical predecessor of modern fusion cooking. The cooking process has two phases. First, the pork belly is simmered in plain water (sometimes with green onion and ginger) for 60 to 90 minutes to render excess fat and partially cook the collagen. Then the braising liquid is added and the heat reduced to the barest simmer for a further two to three hours. The long second-phase braise is essential — at the temperatures involved, collagen conversion to gelatin takes time, and rushing produces chewy, fatty rather than gelatinous, wobbling pork. The test for doneness is a chopstick inserted into the thickest part: it should pass through with no resistance, as though entering a firm jelly.

Cha-kaiseki (茶懐石) — the formal meal served as part of the chaji (full tea ceremony) — is the ancestor of modern kaiseki ryori, but a distinct form with rules more stringent and a philosophy more ascetic than its restaurant descendant. The tea master Sen no Rikyu (1522–1591) codified the cha-kaiseki as the meal that prepares the guest to receive koicha (thick tea): enough food to prevent the stomach from being empty during the tea service (drinking matcha on an empty stomach causes nausea), but never so much as to cause fullness or distraction from the ceremony. The meal consists of: rice (honzen — a formal serving arrangement), miso soup, and a combination of simmered, grilled, and raw preparations served sequentially before the ceremony proceeds to sweets (higashi dry sweets with usucha light tea, namagashi fresh sweets before koicha). The pottery used for cha-kaiseki is typically wabi-aesthetic earthenware (Oribe, Shino, Bizen ware) chosen by the host in coordination with the season, the occasion, and the mood of the ceremony — not the expensive porcelain of formal kaiseki. The strict prohibition against waste in cha-kaiseki (Sen no Rikyu's yaku-zake rule — nothing should remain on the plate when the ceremony is complete) and the requirement that the host cook every dish personally for the guests (no professional caterers) distinguish cha-kaiseki from modern restaurant kaiseki most fundamentally. Modern kaiseki at restaurants descends from this tradition but has developed its own professional and gastronomic priorities.

The relationship between the tea ceremony (chanoyu, 茶の湯, or chado, 茶道 — 'the way of tea') and Japanese food culture is foundational and formative. The tea ceremony, codified by Sen no Rikyu (1522–1591) under wabi-sabi aesthetic principles, required a kaiseki meal served before tea — this meal is the origin of the kaiseki restaurant format that now represents Japan's highest culinary tradition. Rikyu's concept of ichi-go ichi-e (一期一会, 'one time, one meeting') — treating every gathering as unrepeatable — shaped Japanese food culture's obsession with seasonal precision and momentary perfection. The tea ceremony meal exists to prepare the guest physically and mentally for tea: it must warm the body (the soup and rice), provide enough sustenance without fullness (small portions), and create aesthetic experience that heightens sensibility. The sequence — sakizuke snack, sake, main courses — preceded the final bowl of tea. The wagashi served before tea (namagashi, higashi) is specifically calibrated in sweetness to prepare the palate for matcha's bitterness. Without the tea ceremony's aesthetic demands, kaiseki would not have developed its rigorous seasonal, visual, and compositional philosophy. Tea aesthetics — wabi (rustic simplicity), sabi (quiet beauty of age), mono no aware (the pathos of transience) — permeate Japanese food culture.

Chanpon is Nagasaki's defining noodle dish, born from the city's centuries-long role as Japan's sole open port during the Edo period and the cultural interchange it created with China. The dish is attributed to Chen Pingshun, who opened Shikairō restaurant in Nagasaki in 1899 and devised a hearty, inexpensive meal for Chinese students studying in the city. It is therefore neither purely Japanese nor purely Chinese but specifically Nagasakian — a hybrid that could only have emerged from that particular port's history. What separates chanpon from ramen is both process and contents. The noodles — thick, soft, round, made with lye water like ramen but slightly different in composition — are cooked directly in the broth rather than separately, meaning they absorb the stock as they cook and the starch they release thickens it slightly. The broth itself is a cloudy, deeply savoury blend of pork and chicken bones, enriched with lard and seasoned with a light soy tare. The toppings are stir-fried in lard before the broth is added — pork belly, squid, prawns, kamaboko, bean sprouts, cabbage, and sometimes oysters — and this technique means the fat from the stir-fry integrates into the soup, creating the dish's characteristic richness. The vegetables must retain some bite, which requires confident high heat during the initial fry. A cold-weather version called sara udon uses the same toppings and sauce but poured over crispy fried noodles rather than served in soup — demonstrating the dish's adaptability within the same regional tradition.

Chāshū is the braised pork topping that crowns ramen bowls and defines the visual identity of the dish in the Japanese imagination. Despite its name deriving from the Cantonese char siu (barbecued pork), Japanese chāshū is an entirely different preparation — rolled and tied pork belly, braised in a soy-mirin-sake-sugar liquid until the fat layers become gelatinous and the lean sections remain just moist, then sliced into rounds that reveal a spiral cross-section of alternating fat and meat. The roll-and-tie technique is the foundation. A whole skin-on pork belly (or occasionally loin) is rolled tightly into a cylinder against the grain of the meat, secured with butcher's twine at regular intervals, and either seared first or placed directly into the cold braise. The rolling accomplishes two things: it creates the spiral presentation that has become aesthetically canonical in ramen, and it ensures that the braising liquid penetrates the roll from outside inward, creating a gradient of flavour that is most intense at the exterior. Braising liquid composition matters enormously. The balance between soy (salt and umami), mirin (sweetness and body), sake (depth and alcohol extraction), and sugar creates the colour gradient from dark exterior to pale interior. The liquid also doubles as a tare — many ramen shops use the chāshū braising liquid as part of their seasoning sauce, reducing and adjusting it to concentrate the flavour. This creates an elegant circularity: the pork seasons the broth, and the broth flavours the pork. The ideal chāshū slice is 1-1.5cm thick, with visible fat layers that are not fully rendered but translucent — slightly wobbly when placed in a hot bowl, not firm from refrigeration. Many shops torch the slice briefly before service to add a slight char to the fat surface.

Chawanmushi is a delicate steamed egg custard served in a covered cup — the Japanese savoury creme brulee. The flavour is entirely derived from the quality of the dashi, and the texture — smooth, silken, with a slight wobble — is the result of a low egg-to-dashi ratio and a gentle steam. It contains shrimp, chicken, ginkgo nut, and mitsuba (Japanese parsley) hidden beneath the surface.

Dashimaki tamago is the Kyoto refinement of the rolled omelette tradition, distinguished from its Tokyo tamagoyaki counterpart by a dramatically higher dashi-to-egg ratio. Where Tokyo versions prioritise sweetness and a firmer structure, Kyoto's dashimaki tamago is defined by an almost trembling softness — the interior barely set, the outside just kissed by the pan, the whole thing saturated with the umami depth of good kombu-and-katsuobushi dashi. The dish exists because Kyoto's kaiseki tradition demands that every element on the plate carry the flavour of the season and the stock. The omelette is not a side item but a statement: proof that the kitchen's dashi is worth tasting on its own. A ratio of roughly 1:1 egg-to-dashi by volume is standard in Kyoto households; some tea-ceremony kaiseki kitchens push to 60% dashi by weight. Technique is everything. The rectangular tamago pan (makiyakinabe) must be well-seasoned, heated evenly and oiled lightly with a folded paper towel to prevent sticking without creating bubbles. Egg is beaten without incorporating excessive air — stirring rather than whisking. The liquid is poured in three or four thin layers, each layer allowed to just-set before being rolled forward with chopsticks or a spatula, building a loose, layered cylinder. The result is finished by resting inside a bamboo rolling mat (makisu) to set its shape without squeezing out moisture. The final dashimaki tamago is sliced to reveal concentric rings of pale gold. Served with grated daikon and a splash of soy, it is one of Japanese cuisine's most technically demanding simple preparations — and a benchmark by which cooks are judged.

Depachika (デパ地下, department store basement) refers to the extraordinary food halls occupying the basement levels of Japanese department stores — considered among the finest concentrated displays of food culture anywhere in the world. The term combines depāto (department store) and chika (underground). A major depachika like those at Isetan Shinjuku, Takashimaya, or Mitsukoshi Ginza covers thousands of square metres and features hundreds of vendors selling fresh produce, sushi, sashimi, wagashi confectionery, imported cheeses and wines, prepared dishes, bento, pastries, pickles, deli items, and regional specialties from across Japan. The atmosphere is one of hustle, precision, and theatre — vendors shout greetings, samples are offered freely, packaging is exquisite, and every item is treated as a luxury good. Depachika function as a culinary showcase for regional Japanese food producers, seasonal ingredients, and craft confectioners who cannot otherwise reach Tokyo consumers. Gift-giving culture (ochugen and oseibo) drives enormous sales through premium packaging. The competitive intensity means quality standards are extraordinarily high — vendors who cannot maintain them lose their spots to others on waiting lists.

Edamame — young soybeans still in the pod — is Japan's quintessential izakaya snack: served in a bowl, still in their pods, dusted with sea salt, eaten by squeezing the beans directly from the pod into the mouth. They should be bright green, slightly sweet, and tender with a tiny amount of resistance at the bite. The difference between properly cooked edamame and improperly cooked edamame is enormous.

Goya champurū is Okinawa's most iconic dish — a stir-fry of bitter melon (goya), firm tofu, pork (spam, thinly sliced pork belly, or pork luncheon meat), and egg, seasoned with soy and dashi. The word champurū comes from the Okinawan dialect and means something like 'mixed together' or 'chanpuru,' reflecting a broader cultural tradition of mixing disparate elements into something unified — itself a metaphor for Okinawa's history as a crossroads culture absorbing influences from Japan, China, and Southeast Asia. Goya (Momordica charantia) is the defining and most challenging ingredient. The bitter melon's bitterness — from compounds including momordicin and charantin — is its identity, not a flaw to be eliminated. The Okinawan approach to goya respects this bitterness while managing its intensity: the melon is halved, the seeds and white pith (which carry the most concentrated bitterness) are scooped out, the flesh is sliced thinly, then salted and allowed to weep before cooking. This removes some moisture and slightly reduces the sharpest bitterness without destroying the character that makes the vegetable interesting. The stir-fry requires high heat and a specific sequencing. Tofu — pressed firm, torn or cut into large pieces, and pan-fried separately until golden — is the foundation that absorbs the pork fat and sauce without disintegrating. The pork renders its fat into the pan, which then flavours the goya as it cooks briefly at high heat. Egg, beaten and seasoned, goes in last and is stirred through to just-set, binding the other elements loosely. Okinawa's food culture reflects the Ryukyu Kingdom's centuries of trade with China and Southeast Asia, and goya champurū is an edible expression of that crossroads identity — bitter, complex, and unlike anything else in the Japanese culinary canon.

Japanese gyoza: thin-skinned, pleat-folded dumplings filled with pork, nappa cabbage, garlic chive, and sesame oil. Pan-fried in a technique unique to Japanese cooking — yaki-mushi (steam-fry) — where the gyoza is first seared on the flat base until crisp, then steam-finished with water added to the pan and a lid placed on, then finished with the lid off to evaporate the water and re-crisp the base. The result is a gyoza with a glass-crisp bottom and tender, steamed top.

Japanese gyōza are a post-WWII adaptation of Chinese jiǎozi, brought to Japan by soldiers and settlers returning from Manchuria in the 1940s. They have since evolved into a distinctly Japanese dish — thinner-skinned, smaller, with a garlic-heavy filling compared to many Chinese versions, and defined by the hane (wings or skirt) technique that creates a connected, lacy crisp crust across the entire bottom of the pan rather than individual crisp bases. The hane technique is what separates Japanese pan-fried gyōza from the rest of the world's pan-fried dumpling traditions. After the initial pan-frying creates colour on the bottom, a starch-water slurry (katakuriko — potato starch — dissolved in cold water) is added to the pan and the lid is immediately placed on. The steam from the slurry cooks the tops of the dumplings while the liquid reduces and the remaining starch binds the bases together into a single, unified, translucent sheet of crisp starch. When the gyōza are inverted onto a plate, they arrive as a connected flower-like arrangement, the hane visible as a golden-brown, paper-thin lattice. The filling is a specific balance of pork mince, nira (garlic chives), cabbage (salted, squeezed dry, and finely chopped), garlic, ginger, soy, sesame oil, and oyster sauce. The cabbage moisture must be fully expressed before combining with the meat — any residual water makes the filling loose and the skin wet, preventing adhesion. Pleating is the wrapper-sealing technique. The skin is placed in the palm, filling added, and one edge is folded up and pleated in a series of small folds against the flat back edge. A skilled gyōza maker creates seven to nine pleats per dumpling with a single-handed motion. The number and uniformity of pleats indicates craft level.

Hanami (花見, 'flower viewing') is Japan's spring tradition of gathering under cherry blossom trees to eat, drink, and celebrate the fleeting blooms — one of the country's most important seasonal food events that mobilises an enormous food economy each year from late March through early May. The hanami picnic food tradition has its own specific repertoire: sanshoku dango (three-colour skewered mochi), sakura mochi (pink sweet rice cake with cherry blossom leaf), spring sushi (chirashizushi with pink shrimp and sakura decorations), hanami bento (elaborate packed lunches) and sake or beer. The cherry blossom viewing season lasts only 1–2 weeks per region before the petals fall — this transience (mono no aware) is central to the cultural meaning. The food choices for hanami reflect the season: sakura-flavoured wagashi, spring pickles, bamboo shoot dishes, and the first fresh spring vegetables (nanohana rapeseed). The sakura salt preservation technique (preserved cherry blossoms used in sakura-yu tea and sakura mochi) is a specific food technology developed to capture the flavour of the blossoms beyond their brief season. Major parks (Ueno in Tokyo, Maruyama in Kyoto) see millions of hanami participants who have organised space reservations weeks in advance.

Hayashi raisu (Hayashi rice) is a Japanese Western-influenced dish (yoshoku) consisting of beef and onions simmered in a rich demi-glace and tomato-based sauce served over plain rice—essentially a Japanese interpretation of beef stew that emerged during the Meiji era (1868-1912) as Japan opened to Western influence and ingredients. The name's origin is disputed: possibly from 'Hashed beef rice' (hashed corrupted to hayashi), from a chef named Hayashi, or from the French 'haché.' The sauce is darker and richer than typical Western beef stews—built on a combination of Japanese-style demi-glace (yoshoku demi-gura), tomato paste, red wine, and a sweetening element (typically a small amount of sugar or fruit, reflecting Japanese yoshoku's characteristic sweetness). Unlike curry rice (karē raisu), which has a thicker, more robust spice character, hayashi rice has an elegant, glossy, wine-dark sauce with a beefy depth. The dish represents the broader yoshoku tradition—Western dishes domesticated through Japanese flavor preferences (sweeter, more glossy, served with Japanese rice rather than bread). Button mushrooms (marusōmen) are typically included. Hayashi rice is considered more 'refined' than curry rice and appears on the menus of older Western-style restaurants (yoshoku-ya) in Tokyo.

The Japanese set lunch (teishoku, 定食 or hiru-gozen, 昼御膳) is one of the great daily rituals of urban Japanese food culture — the precisely organised, reasonably priced midday meal sold by restaurants from approximately 11:30 to 14:00 offering a complete ichiju sansai meal at a fixed price. The teishoku tradition makes one of the world's most nutritionally balanced restaurant meal formats available to ordinary workers at affordable prices. A standard teishoku consists of: white rice (unlimited refills at most establishments), miso soup, a main dish (yakizakana grilled fish, tonkatsu pork cutlet, karaage fried chicken, hamburger steak, sashimi, or daily special), one or two side dishes, and pickles. The price — typically 800–1,500 yen in Tokyo (2025) — represents extraordinary value for the ingredient quality and composition. The teishoku format is also a vehicle for restaurant specialisation: a grilled fish teishoku restaurant serves only grilled fish sets; a tonkatsu teishoku restaurant serves only pork cutlet sets. The daily special (higawari, 日替わり) communicates with regular customers what is freshest in the kitchen that day, and rewards loyalty with variety.

Hokkaido's transformation into Japan's dairy heartland began in the Meiji era when the government, seeking to develop the sparsely populated northern island, brought American and European agricultural experts to establish modern farming. Today Hokkaido produces over 50% of Japan's milk and virtually all of its premium butter and cream, with a pastoral landscape visually reminiscent of Normandy or Vermont. The culinary culture built around Hokkaido dairy is among Japan's richest in a single ingredient category: Hokkaido butter (especially from Tokachi, Yotei, and Niseko areas) has a higher fat content and creamier profile than mainland Japanese dairy due to the island's cool climate, rich grassland, and longer pastoralization periods. The specific applications: Soup curry (a Sapporo-invented thick, butter-enriched curry soup with large vegetable pieces) is Hokkaido's most distinctive culinary export; Ishikari-nabe is a Hokkaido hot pot with miso-butter broth, salmon, and potato; corn soup (konn supa) made from fresh Hokkaido sweet corn and milk is a summer institution; batter-fried escallops (hotate) in panko served with a rich cream sauce reflects Hokkaido's coastal produce meeting its dairy industry; cheese culture — Hokkaido Camembert (Tokachi, Biei), fresh mozzarella, and a growing artisan cheese scene including Hokkaido Gouda — is the most developed artisan dairy culture in Japan. The jaga butter (baked potato with generous butter) at Hokkaido road stations is the most democratic expression of the same idea. Premium Hokkaido milk soft-serve (see ice cream entry) is consumed as a regional identity statement.

Hōtō is Yamanashi Prefecture's signature dish — a thick stew of wide, flat udon-style noodles cooked directly in a miso broth with kabocha pumpkin, root vegetables, and pork or chicken. It is a winter staple in a landlocked prefecture whose cold climate and mountainous terrain historically made rice cultivation difficult, making wheat (for noodles) and stored root vegetables the dietary foundation of local cooking. The noodles are the key differentiator. Unlike standard udon, hōtō noodles are not parboiled or rinsed — they are added to the simmering stew in their raw, uncooked state, directly from the dough. The noodles cook in the miso broth and simultaneously thicken it with their released starch, producing a dish whose liquid is not a soup but something much thicker and starchier. The texture of the finished noodles is softer than typical udon — almost dumplinglike — because they have been simmered in a flavoured liquid rather than boiled in plain water. The noodle dough itself is different: hōtō uses a lower hydration, rougher dough with no alkaline agent. It is rolled thick, cut wide, and cooked without polishing. This produces a more rustic, absorbent noodle than the refined smooth texture of proper udon. Kabocha pumpkin is the essential vegetable. Its natural sweetness contrasts with the miso's saltiness and the earthy root vegetables (daikon, carrot, gobo), and it partially dissolves into the broth during cooking, adding body and a warm orange hue. The dish is almost always made in a ceramic nabe pot and served communally from the pot at the table. Hōtō is associated with Takeda Shingen, the famous 16th-century warlord of Kai Province (modern Yamanashi), who reportedly fed his troops the dish during military campaigns — a connection that makes it a point of regional pride.

Chicken halves marinated in a sweet-savoury sauce (soy, brown sugar, ginger, garlic, ketchup, pineapple juice, sesame oil), then grilled over kiawe coals between hinged wire baskets. The critical technique: the sauce is not applied at the beginning. It is applied in multiple layers during the final minutes of cooking. Each application caramelises into a thin glaze before the next is brushed on. One application produces teriyaki chicken. Multiple applications during turning produce huli huli. The layering is the technique.

Ichiju sansai (一汁三菜, 'one soup, three dishes') is the defining meal format of traditional Japanese cooking — a structural template that has organised Japanese eating for over a millennium. The format specifies one soup, one main dish (shusai), and two side dishes (fukusai), all served with rice and pickles. The main dish is typically a protein (fish, meat, tofu) in a specific cooking method — grilled, simmered, or fried. The two side dishes are complementary in method, texture, and flavour: typically one simmered vegetable dish and one fresh or lightly prepared vegetable dish. The soup — miso soup or clear suimono — provides the liquid element that facilitates rice eating. This structure is not merely aesthetic but nutritionally sophisticated: it ensures protein, carbohydrate, multiple vegetables, fermented food (pickles), and a liquid at every meal. The format scales up — ichiju gosai (one soup, five dishes) describes more elaborate meals — and scales down. The kaiseki meal is ichiju sansai elaborated into a sequence. Japanese home cooking, school lunches (kyūshoku), and traditional restaurant set meals (teishoku) all reflect this fundamental structure.

Imoni is Japan's most participatory regional food event — an outdoor communal stew of taro root and beef, cooked in massive quantities over river stones in Yamagata Prefecture each autumn. The city of Yamagata holds an annual imoni festival on the Mamigasaki River where vats holding several thousand portions are cooked on an industrial scale, but the true form of imoni is the one cooked by families, friends, and colleagues around an outdoor fire on the riverbanks. The dish itself is a soy-and-sake based soup of taro root (satoimo), thinly sliced beef, konnyaku, and vegetables. The taro root — Yamagata grows some of Japan's best quality satoimo — is the heart of the dish. It breaks down at the edges during cooking, releasing a natural starchiness that thickens the broth into something between a soup and a stew. The exterior of each piece becomes slightly slippery and the interior perfectly creamy. Yamagata's imoni is defined in contrast to the Miyagi Prefecture version, which uses pork and miso instead of beef and soy. This regional distinction is passionately maintained and debated — Yamagata people consider their soy-beef version the original and 'correct' form. The debate mirrors the broader Japanese cultural habit of using food as a marker of regional identity. The outdoor cooking context is inseparable from the dish. Imoni is not simply a recipe but an event — a late-September to October ritual that signals the arrival of autumn. The smoke from the fire, the chill in the air by the river, the communal ladle-to-bowl service, and the progression from stew to zōsui as the event winds down are all part of the imoni experience. Eating it indoors from a regular stovetop is technically possible but culturally diminished.

Ishikari nabe is Hokkaido's most celebrated hot pot — named for the Ishikari River basin where Hokkaido's salmon population was historically so abundant that it sustained the Ainu indigenous people for centuries before Japanese settlement. The dish brings salmon, tofu, vegetables, and potato together in a miso-enriched broth that reflects Hokkaido's dual food identity: the marine richness of its coasts and the dairy-influenced, hearty cooking of its agricultural interior. The defining characteristic of ishikari nabe is the use of sake lees (sake kasu) as a secondary seasoning alongside the miso base. Sake kasu — the pressed solid residue from sake production — adds a fermented depth, gentle sweetness, and creamy body to the broth that distinguishes it from any other miso hot pot style. Hokkaido is Japan's largest sake kasu producer by virtue of its active brewery industry, and the ingredient's inclusion is both practical (proximity to supply) and flavourful. Salmon used in ishikari nabe must be fresh, not cured or smoked. The fish is cut into thick bone-in pieces so that the collagen and fat in the bones enrich the broth as it simmers. Unlike delicate Japanese broths that would be overpowered by strong fish, the miso base of ishikari nabe absorbs and integrates the salmon's oils and oceanic richness into a cohesive whole. Vegetables — hakusai (napa cabbage), potato, daikon, burdock, carrot — are added in order of cooking time, with the potato (a Hokkaido staple) often surprising visitors with its presence in a Japanese hot pot. Butter is sometimes added to the broth as a contemporary variation, reflecting the dairy culture of Hokkaido's agricultural western regions.

The izakaya (居酒屋, literally 'stay-sake-shop') is Japan's most democratic food institution — a casual drinking establishment that serves small dishes alongside beer, sake, shochu, and highballs. The word combines i (to stay) with sakaya (sake shop), reflecting the Edo-period evolution from sake retailers who allowed customers to drink on the premises. Modern izakaya range from tiny counter seats with a handful of dishes to large chain establishments (Torikizoku, Watami, Tsubohachi) serving hundreds of standardised items. The food culture is defined by the concept of atsukan (warm sake) and tsukidashi — the mandatory small appetiser placed before ordering that constitutes an automatic table charge. Izakaya menus exist to match alcohol: edamame, karaage, agedashi tofu, yakitori, sashimi, salted cucumber, grilled fish, chawanmushi, and yakisoba are the genre-defining repertoire. The izakaya session typically progresses from light refreshing dishes to heavier grilled items to starchy ending dishes (締めのご飯 — 'shimenohangou' rice or ramen to close). Group ordering culture dominates — dishes are shared across the table. Staff shout 'irasshaimase' on entry; leaving often requires sustained effort to attract a busy server.

Japan's traditional calendar system includes the 72 ko (候 — 'micro-seasons') — the subdivision of the 24 solar terms (sekki) into three five-day intervals each, resulting in 72 distinct seasonal 'moments' through the year, each characterised by specific natural phenomena: when the cherry blossoms first open; when the fireflies appear; when the deer begins to shed velvet; when the first frost falls. This system, derived from Chinese astronomy and adapted to Japan's specific climate through observation over centuries, provides the deepest temporal framework for Japanese seasonal food culture — going beyond the four seasons or even the 24 solar terms to describe the exact quality of a specific five-day window within the year. For professional kaiseki chefs and serious washoku practitioners, the 72 ko provide the vocabulary to specify not 'spring' or even 'early spring' but 'the period when the warm winds blow and the ice begins to melt' (koharu no kaze, late January–early February) — and to match ingredients, ceramic choices, and garnishes to that specific moment. The system connects Japanese food culture to the agricultural and ecological calendar in a way that is rare in any other culinary tradition. A selection of ko particularly relevant to cooking seasonality: 'Ika no ko saku' (butterbur buds sprout, February); 'Sakura hajimete hiraku' (cherry blossoms first open, March); 'Koe no shoku hitsuji ni tarazu' (sheep's stomach is no longer enough — meaning the warmth has arrived and spring food is coming, April); 'Hotaru tobibashiru' (fireflies flying, May–June); 'Inaho no mi naru' (rice ears ripen, September).

The traditional Japanese breakfast (asa-gohan, literally 'morning rice') is perhaps the most complete expression of ichiju sansai (one soup, three sides) as a daily living practice rather than a high-ceremony event. At its full expression in a ryokan (traditional inn), it assembles: steamed white rice, miso soup (with seasonal tofu, wakame, or root vegetables), grilled salmon or salted fish, tamagoyaki (sweet rolled omelette), natto (fermented soybeans), tsukemono (pickles), a small dish of tofu or aemono, and green tea. This is not restaurant performance but the way several generations of Japanese families ate before Western breakfast foods (toast, eggs and coffee) replaced it for weekday speed. The concept of 'having rice in the morning' (gohan ga taberarete shiawase — 'happy to be eating rice') encapsulates a cultural relationship with cooked rice that extends beyond nutrition. At premium ryokan — Kyoto's Tawaraya, Hakone's Gora Kadan — the morning breakfast has become as celebrated as the evening kaiseki dinner, with seasonal grilled fish, regional house-made pickles, and ceremonially prepared rice as the centrepieces. The contrast between this tradition and the increasingly common Western-style hotel breakfast reflects ongoing cultural negotiation around food identity. Onsen tamago — eggs soft-cooked in geothermal spring water — is an iconic Japanese breakfast element, their whites barely set, yolks silky, served with dashi broth and soy.

Japan has produced some of the world's most influential food competition and food media formats — most significantly Iron Chef (Ryori no Tetsujin), the television cooking competition format that ran on Fuji TV from 1993 to 1999 and became one of Japan's most globally recognised TV exports. Created by producer Kanta Ishizuka and hosted by the eccentric Chairman Kaga (Takeshi Kaga), Iron Chef combined theatrical camp, genuine culinary skill, and the pressure of the one-hour cooking battle to create a format that was later recreated in the United States (Iron Chef America) and globally. The show elevated Japanese culinary culture internationally, introducing global audiences to kaiseki technique, ingredient philosophy, and the shokunin ethic of total commitment to craft. Beyond Iron Chef, Japan's culinary competition culture spans: the Bocuse d'Or Japanese national team (consistently high-performing in the biennial world competition), the World Sushi Cup, national tekone (hand-technique) competitions for soba, udon, and tempura craftsmen, and the regional wagashi competitions where confection makers demonstrate mould design and hand-shaping skills. The Oishinbo manga (1983–present, by Tetsu Kariya and Akira Hanasaki), serialised in Big Comic Spirits magazine, is the longest-running food education narrative in any medium — its protagonist Shiro Yamaoka investigates ingredients and techniques across Japanese and world cuisine, teaching millions of Japanese readers about food culture over 40 years. The manga form of food education is distinctly Japanese — also exemplified by Cooking Papa, Bambino, and Bartender.

Mottainai (もったいない) — a Japanese concept with no direct Western equivalent, expressing profound regret over waste and a Buddhist-rooted reverence for the intrinsic value of all things — is one of the most practically important philosophical principles in Japanese cooking. The concept's culinary expression goes far beyond environmental ethics into a positive creative tradition: the culinary art of finding maximum use for every component of an ingredient, transforming potential waste into genuine culinary value. Practical mottainai in Japanese cooking: dashi kombu shredded and simmered into kombu tsukudani after extracting the dashi; used katsuobushi reused in niban dashi (secondary stock) after the first extraction; daikon peel stir-fried with sesame and soy as a side dish; kabocha seeds dried, salted, and roasted; fish bones (kara-age of the backbone — deep-fried until crispable) served as a sake accompaniment; nori scraps used in sesame-nori seasoning; vegetable trimmings composted or added to stock. At the philosophical level, mottainai is also the sensibility that produces Japan's extraordinary ingredient quality — if every component of a fish is used with the same care as the prized fillet, the quality of that care elevates the entire cooking tradition. The phrase 'mottainai kara taberu' ('I eat because to waste it would be mottainai') expresses not greed but reverence. The Zen Buddhist influence is direct — the oryoki (formal monk's eating bowls, licked clean) is the most extreme expression of the same value.

Japanese curry rice (kare raisu) is one of Japan's most consumed dishes — sweeter, milder, and thicker than Indian curry, served over short-grain rice with fukujinzuke (pickled vegetables) on the side. The curry roux is typically made from a block (S&B Golden Curry or Vermont Curry) that already contains the spice blend, oil, and flour thickener. The dish is simple, comforting, and reliable — the Japanese home cooking equivalent of British shepherd's pie.

Japanese curry — kare raisu (curry rice) — is one of the most consumed dishes in Japan, eaten more frequently by Japanese households than sushi, ramen, or soba, yet it is also one of the most misunderstood from outside: it is not Indian curry, not Thai curry, and shares only the word 'curry' with its distant ancestor. Arriving via British naval ration culture in the Meiji era (carried through colonial India into Royal Navy ship provisions and then Japanese Navy kitchen training), Japanese curry was adapted through a roux base — flour cooked in oil or butter until blonde — into which curry spice blend was incorporated. The result is a thick, glossy, mild sauce served over Japanese short-grain rice. The canonical civilian version is the storebought S&B Golden Curry or Vermont Curry roux block — a national institution. The restaurant version ranges from simple home-style (katsu kare: tonkatsu pork cutlet on curry rice) to the extraordinarily complex versions produced by Tokyo specialist curry restaurants (the 'spice curry' movement originating in Osaka's cafe scene) that layer 30+ spice compounds and rival Indian restaurant complexity. Regional variations include: Kanazawa's seafood curry, Hokkaido's buttered corn curry, Yokosuka navy curry (historically based on the original Royal Navy recipe, with a specific low-spice profile), and the Keema (minced meat) curry that has become a Tokyo breakfast food. Fukujinzuke — a blend of pickled vegetables in sweet soy — is the obligatory condiment, as is rakkyozuke (pickled shallots).

Omiyage (お土産 — souvenir gift) is one of the most deeply embedded food practices in Japanese social culture: the obligation to bring edible souvenirs from any journey, trip, or travel experience and distribute them among colleagues, family members, and social superiors upon return. This is not a casual tradition but a social obligation so deeply ingrained that Japanese train stations, airports, and tourist destinations orient significant commercial infrastructure around it — the ekiben (train station bento) is one dimension of this; the omiyage confection shops that occupy 30–40% of all major train station retail space are another. The economics of omiyage create a national confection industry worth trillions of yen annually: regional producers compete intensely to have their products designated as the 'authentic' local omiyage of their region. The most successful examples have become nationally recognised: Tokyo Banana (individually wrapped banana-shaped sponge cake with banana cream, introduced 1991 — despite Tokyo having no banana heritage, it became one of Japan's top-selling omiyage products); Shiroi Koibito (white chocolate langue de chat from Hokkaido, produced by Ishiya since 1976 — now produced at their theme park factory in Sapporo); Yatsuhashi (Kyoto cinnamon rice wafer — the undisputed champion of regional confection identity, sold in raw (nama) and baked forms for centuries); Ippodo Matcha products (Kyoto matcha for the sophisticated buyer); and hundreds of regional equivalents. The social function of omiyage is not primarily gustatory — the packaging, regional branding, and the act of giving and receiving are as important as the taste.

Japan's relationship with food representation extends into two extraordinary cultural phenomena: the art of Japanese food photography (ryori shashin) as a distinct discipline, and the uniquely Japanese institution of shokuhin sampuru — realistic plastic food models displayed in restaurant windows to help customers order without a language barrier. Shokuhin sampuru (食品サンプル — 'food sample/specimen') are wax or plastic three-dimensional reproductions of menu items created with extraordinary realism — photographically indistinguishable from the actual dishes, including the translucency of ice, the condensation on beer, the steam rising from noodles, and the precise distribution of sauce on rice. The industry originated in Osaka in 1932, credited to Takizo Iwasaki of the Iwasaki-be company (still one of Japan's two major sampuru manufacturers, along with Maizuru). The production technique evolved from wax molding (using actual food as moulds) to modern vinyl chloride casting with hand-painting and finishing. Sampuru serve a cultural function beyond menus: they are displayed in tourist shops as highly desirable souvenirs, with miniature versions (key chains, fridge magnets of individual sampuru items) generating a significant secondary market. Beyond sampuru, Japan's professional food photography culture (ryori shashin) represents one of the world's most technical and demanding disciplines — the precision required to replicate the exact heat, moisture, and glistening of freshly prepared Japanese food in a photographic context has generated entire schools of food styling technique that subsequently influenced global food media.

Omakase — 'I leave it to you' — is the dining protocol in which the guest surrenders menu selection to the chef entirely, receiving instead a sequence of dishes chosen according to the chef's assessment of what is best on that particular day. At the highest level (sushi omakase at a counter seat before a master such as Jiro Ono, kaiseki omakase at Kikunoi or Kichisen), this is one of the world's most ritualised fine-dining experiences, governed by detailed etiquette that most foreign guests and even younger Japanese diners are unfamiliar with. The fundamental etiquette principles: arrive on time (even 5 minutes early) — in many establishments, the chef begins preparing the sequence before service starts; communicate dietary restrictions before booking, not at the table; do not disturb the progression with requests or modifications mid-service; eat nigiri sushi immediately when placed (at temperature equilibrium with the body-warm rice is the intended moment); do not rearrange items or photograph excessively between courses; conversation with the chef at the counter is expected and appreciated but should not dominate; sake or beer ordering should follow the chef's suggestions or be made before service begins; the price is what it is — do not ask for a discount or itemised bill in a traditional omakase format; and tip culture in Japan is traditionally absent (and can cause embarrassment). The counter seat itself carries significance: proximity to the chef grants the guest visual access to the preparation, a privilege that carries the obligation of attentiveness.

Omurice (オムライス — from 'omelette' and 'rice') is one of Japan's most beloved yoshoku comfort foods, consisting of ketchup-seasoned fried rice (typically with chicken, onion, and peas) wrapped or topped with a thin, barely-set omelette and finished with ketchup drawn in a spiral, message, or decorative pattern on top. The dish was invented in the early 1900s at Renga-tei restaurant in Ginza, Tokyo — one of Japan's oldest yoshoku restaurants — and has been a staple of children's menus, family restaurants (famiresu), and home cooking ever since. The omelette preparation divides into two schools: the traditional hard-wrapped style where a fully cooked omelette encloses the rice; and the modern (Osaka-derived) torori (とろり — 'dreamily soft') style where an extremely soft, barely-set, custard-like omelette is placed on top of the rice and slit open tableside with a knife to drape over the rice in a golden cascade. The torori style was popularised by Osaka's Hokkyokusei restaurant and filmed going viral — the sight of the perfectly soft omelette opening like a flower over the rice became one of food media's most-viewed moments. The rice itself is also variable: standard ketchup-rice with chicken; demi-glace rice (more sophisticated, used at higher-end omurice restaurants); and the butter-soy variation for a different flavour profile. High-end omurice restaurants in Tokyo (Takumicho, Yukimura) treat it as a fine-dining subject, using clarified butter for the omelette, premium chicken, and house-made demi-glace.

Jingisukan — named after Genghis Khan and reflecting a romanticised Japanese imagining of Mongolian steppe barbecue — is Hokkaido's beloved lamb and mutton grilling tradition, distinctive enough to constitute a regional cuisine unto itself. It is cooked on a domed cast-iron grill (the 'Genghis Khan' pan) that allows lamb fat to render from the convex centre, flow down the slopes, and collect in a moat around the edge where vegetables — onion, bean sprouts, pumpkin, and peppers — are simultaneously cooked in the rendered fat and juices. Lamb arrived in Hokkaido through government-sponsored sheep farming programs in the Meiji era (late 19th century) as part of the broader Hokkaido development project that aimed to make the northern island agriculturally productive and strategically significant. The sheep were imported for wool production, but the meat — initially considered a by-product — eventually became a defining element of Hokkaido's food identity, particularly in Sapporo and the Tokachi and Kamikawa regions. The grill's dome design is functionally elegant. Thin slices of lamb (or thicker cuts of mutton in more traditional versions) are placed on the crown of the dome over the heat source, where fat renders quickly and the meat cooks in a flash. The flavour is enhanced by the lamb fat that drips down and smokes as it hits the hot iron, creating a characteristic aromatic smoke that is part of the jingisukan experience. This is distinctly not a clean or odour-free cooking method — the lamb smoke is considered appealing, and the communal, informal nature of eating around a smoking grill is intrinsic to the culture. The dipping sauce (called 'tare' in this context) is typically a soy-and-apple or soy-and-pear based liquid with ginger, garlic, and sometimes dried chilli — a sweet-savoury, slightly fruity contrast to the lamb's richness.

Futamono ('lidded things') is the formal lidded soup course in a kaiseki meal—typically the second course following sakizuke (appetizer)—and is considered by many Kyoto masters to be the most technically demanding course in the entire kaiseki sequence. The futamono consists of a clear soup (suimono) served in a lacquer soup bowl (soup-wan) with a fitted lid, containing a carefully selected combination of three to five precisely prepared ingredients that represent the season and demonstrate the chef's knife skills, dashi quality, and aesthetic judgment simultaneously. The contents must be seasonally coherent, visually balanced, and taste as beautiful as they look. A classic spring futamono might contain: hamaguri (hard clam) removed from shell, kinome-topped fu (wheat gluten), and mitsuba trefoil—the dashi must be perfect ichiban of the highest purity. The lidded bowl serves two functions: it maintains temperature and builds anticipation—lifting the lid releases a concentrated puff of fragrant steam and reveals the composition within. This theatrical reveal is an intentional designed moment. The ingredients must be placed with precise deliberateness—not floating randomly but positioned to be discovered as a small visual composition. The soup temperature at service must be near-boiling (65-70°C) as the lid and lacquer bowl retain heat longer than uncovered ceramic.

The hassun is the structural and philosophical heart of a kaiseki meal — a cedar-wood tray (hassun means 'eight sun,' approximately 24cm square) bearing a curated arrangement of seasonal small bites that sets the rhythm and theme for everything that follows. It is the course that most clearly demonstrates the kaiseki principle that food is an expression of the season, the place, and the relationship between host and guest. The composition rules of hassun are specific. One item must come from the sea (umi no mono), one from the mountain (yama no mono), and their arrangement on the tray must reflect the season — asymmetrical, spare, never symmetrical or overly decorative. The items should contrast in texture, temperature, and form, and the tray itself — plain cedar, never lacquered for this course — is part of the presentation. After the host serves sake to guests from this tray, the formality relaxes slightly; hassun is also a transitional course. What makes hassun technically demanding is that each small item must be complete in itself — properly seasoned, at the correct temperature, and visually distinct — while also working as part of the total composition. None of the items are afterthoughts. A pickled mountain vegetable placed beside a piece of grilled fish must contrast without competing. The grill marks on the fish must be clean and intentional. The course reflects Kyoto's kaiseki philosophy of shun — eating at the precise peak of seasonal availability. A chef who serves hassun out of season, or with ingredients that do not reflect the moment, has failed regardless of technical execution. Hassun is as much about timing and sourcing as it is about cooking.

Kakuni manju is the marriage of two great traditions in southern Japanese cooking: kakuni (the slow-braised soy-mirin pork belly described separately) and manju (the steamed bun tradition that arrived from China and became a vehicle for sweet and savoury fillings across Japan). In its savoury form, kakuni manju is specifically associated with Nagasaki's shippoku cuisine and the broader Kyushu region, where the combination of Chinese bun technique and Japanese-Chinese braised pork creates a dish that is emblematic of the southern ports' hybrid culinary identity. The bun itself is made from a yeast-leavened or baking-powder-leavened flour dough — lighter than Chinese baozi dough, with a slightly thinner skin that steams to a soft, pillowy texture without the dense chew of thicker buns. The dough is formed into rounds approximately 8-10cm in diameter, filled with a single slice of kakuni plus a small dab of Japanese mustard (karashi), then gathered and pleated at the top and placed pleat-side down for steaming. The fold is hidden beneath, producing a smooth dome when served. The filling presents specific challenges. Kakuni is slippery and gelatinous when warm — the collagen that makes it perfect in the pot makes it difficult to handle. The slice must be taken from a cold kakuni, placed on the centred dough, and sealed before the warmth from the hands melts the fat and makes sealing difficult. Some preparations wrap the kakuni in a thin blanched cabbage leaf before placing in the bun to manage this. Steaming is the final technique. The filled buns are proofed briefly (10-15 minutes), then steamed over boiling water for exactly 12-15 minutes — enough for the dough to cook through and expand fully, not so long that it becomes gummy or collapses. The texture should be springy when tapped gently on the dome.

Kamameshi — literally 'pot rice' — is rice cooked and served in an individual iron pot (kama) with ingredients layered on top that steam into the rice as it cooks, infusing it with their juices and flavours. The dish has medieval origins as a way of cooking large communal meals, and became a refined individual portion format at Toraya restaurant in Asakusa, Tokyo in the late Meiji or Taisho period. Today it is strongly associated with ekiben (train station bento) culture and regional tourism, with each area claiming its own signature topping combination. The technique is more demanding than it appears. The rice and liquid must be calibrated exactly to the volume of the pot, as there is no way to check or adjust without lifting the lid and losing steam. The broth used instead of plain water — a seasoned dashi-soy mixture — must account for the moisture that will be released by the toppings during cooking. Too much liquid produces mushy rice; too little leaves the bottom burning before the top has cooked. The okoge — the lightly scorched crust that forms on the bottom of the iron pot — is considered a prize. Unlike a failed result in other rice cookery, a slight crust in kamameshi is intentional and desirable, adding a toasted, nutty note to the dish. After the rice is eaten, hot water or green tea is poured into the pot to loosen the crust for zōsui (rice porridge), making kamameshi a two-stage eating experience. Regional topping variations include chicken and burdock root (the Tokyo standard), crab and seafood (coastal versions from Hokuriku), mushroom and bamboo (Kyoto kaiseki adaptations), and game birds or venison in mountain regions.

The most fundamental culinary distinction between Kansai (Osaka-Kyoto) and Kanto (Tokyo) Japanese cooking is the approach to seasoning: Kansai uses light-colored usukuchi soy sauce (paradoxically higher in salt than dark soy) as its primary seasoning in order to preserve the natural colors of ingredients, while Kanto uses darker, more robustly flavored koikuchi soy sauce. This single difference cascades across every aspect of both regional cuisines. Kansai nimono (simmered dishes) have pale golden, translucent broth that shows ingredients clearly; Kanto nimono are richer, darker, more assertively flavored. Kansai clear soups achieve near-transparent beauty; Kanto miso soups are earthier. Kansai uses a higher dashi-to-seasoning ratio in most preparations, creating a cuisine that is about the quality of the dashi stock more than the seasoning. Oden, the winter hot pot, clearly illustrates the difference: Kansai oden has pale, fragrant broth; Kanto oden is dark soy-rich. Kansai's culinary philosophy prioritizes visual beauty, ingredient expression, and dashi depth over assertive seasoning. Kanto prioritizes robust flavor satisfaction. Neither is superior—they represent different articulations of Japanese culinary values.

Kappo (割烹 — from katsu 'cut' and po 'cook') is the Japanese restaurant format in which a single counter separates the guest from the chef working in full view, creating an intimate, interactive dining experience distinct from the ceremony-heavy kaiseki format and the purely social izakaya. Kappo emerged in Osaka's Meiji-era culinary culture as a middle path between street food and formal banquet dining — offering high-quality, freshly prepared food in a setting where guests could watch the preparation, converse with the chef, and order à la carte rather than accepting a fixed course. The physical layout is defining: a long wooden counter (typically hinoki or sugi wood), the chef working directly in front of guests at close range, the kitchen visible (and often the dashi, stocks, and prep work ongoing during service). Guests interact with the chef directly — asking about the day's fish, requesting variations, discussing the season's ingredients. This directness is explicitly valued in kappo culture: the chef-guest relationship is considered part of the dining experience rather than a service transaction. In Osaka specifically, kappo is the dominant high-end dining format — Osaka food culture's 'kuidaore' directness and less ceremony-bound ethos makes kappo more natural than Kyoto's formal kaiseki. The best kappo restaurants operate on referral systems — acquiring reservations requires introduction from existing guests or the right connections. Notable Osaka kappo masters (Nakamura Niro at Nora, various unnamed generational masters) work in a tradition that values 'pure cooking' (junpaku no ryori) without excessive ceremony or decoration.

Kare pan (curry bread) is Japan's most beloved savory bread product—a soft, enriched dough encasing Japanese curry filling that is coated in panko breadcrumbs and deep-fried until golden, creating a crispy shell with a savory, spiced filling interior. The preparation represents a Japanese innovation that combined German-style enriched bread dough (introduced through Meiji-era German baking instruction), the Japanese curry tradition, and the tempura/tonkatsu frying tradition into something entirely new. The dough is slightly enriched with milk, egg, and butter for softness; the curry filling is a thick, concentrated Japanese curry with potato and ground meat; the panko coating is pressed firmly before frying at 170°C until deeply golden. Freshly fried kare pan from a neighborhood bakery (pan-ya) is one of Japan's most quintessential convenience foods—found in every bakery, convenience store, and train station kiosk. The quality ranges from mass-produced to artisanal with restaurant-quality curry fillings. Kare pan is typically eaten hot, standing in front of the bakery or on a train, and the crunch of the panko exterior against the fragrant curry interior is the defining sensory experience. Several bakeries compete for regional 'best kare pan' recognition as a legitimate culinary category.

Karinto is one of Japan's oldest deep-fried confections—kneaded dough made from wheat flour, baking powder, and brown sugar that is extruded through a die into short cylindrical or irregular stick shapes, then deep-fried until puffed and golden, and finally coated in a boiled brown sugar or black sugar syrup that hardens as it cools. The result is a light, airy, intensely sweet snack with a brittle-crispy exterior and hollow puffed interior. The name may derive from the Chinese term for fried candy. Karinto has been made in Japan for over 1,000 years (its origin is attributed to early Nara period temple confectionery from Chinese influence), and while it is now considered an everyday snack, its appearance at traditional tea ceremonies and ancient festivals reflects an earlier ceremonial status. The black sugar (kurozato) version using Okinawan or Amami black sugar (muscovado-like unrefined cane sugar) is considered superior for its deeper molasses flavor. Quality differences between mass-produced and artisanal karinto are significant—the best versions have a complex brown sugar sweetness with faint caramelized notes, while cheap versions taste only of white sugar and oil. Karinto is sold in paper bags at traditional sweet shops (wagashi-ya), department stores, and as regional souvenirs.

Katsu curry is one of Japan's great comfort dishes: a breaded and fried pork or chicken cutlet, sliced and placed on Japanese rice, drenched in a thick, mild, sweet-spiced Japanese curry sauce. The curry is not Indian — it is a Japanese interpretation of a British interpretation of an Indian preparation, arriving through the Victorian-era colonial British navy. It is mild, sweet, and deeply umami-forward from the roux.
