Japan — unagi consumption documented since Jomon period; kabayaki style (skewer + grill) developed Edo period; Kanto/Kansai divergence formalized 17th-18th century
Unagi (鰻, freshwater eel) preparation in Japan is an extremely specialized art — the Kanto (Tokyo) and Kansai (Osaka, Kyoto) styles represent fundamentally different cooking philosophies for the same fish. Kanto kabayaki: eel split down the back, skewered, steamed first (mushi), then grilled with tare — the steaming renders excess fat for a lighter result. Kansai kabayaki: split from the belly (avoiding the samurai's implication of belly-cut), grilled directly without steaming — richer, fattier result. The tare (dipping/basting sauce) at specialized unagi restaurants is maintained for decades — the accumulating fat and caramelization creates increasing complexity.
Rich, slightly sweet soy-glazed eel with charcoal smoke — one of Japan's most deeply satisfying umami combinations
{"Kanto technique: back-split → skewer → steam 20-30 min → grill → baste tare 3-4 times","Kansai technique: belly-split → skewer → direct grill → baste tare","Tare construction: soy + mirin + sake + sugar reduced, eel bones added for depth","Tare aging: restaurant tare maintained for years — each basting adds rendered eel fat","Charcoal grilling: binchotan charcoal for maximum heat concentration and minimal smoke","Unadon vs unaju: unadon in bowl; unaju in lacquered box — same food, different presentation"}
{"Sansho pepper on unagi: ground sansho powder sprinkled on finished unagi — traditional accompaniment","Hitsumabushi (nagoya): eel on rice eaten three ways — plain, with condiments, then as ochazuke","Tare test: properly made tare should be glossy, coat a spoon, taste sweet-savory with depth","Doyo no ushi no hi: traditional mid-July day to eat unagi for energy — busiest day for eel restaurants","Wild vs farmed: wild unagi (natural river eel) is increasingly rare and premium; most is farmed in Hamana Lake"}
{"Skipping Kanto steam step — fat doesn't render; result is too rich and oily","Burning tare during final grill — sugar in tare burns easily; close attention needed","Cold eel on rice — unagi must be served on rice immediately, piping hot — cooling toughens texture"}
