Japan — nabe (hot pot) as universal winter cooking tradition; chankonabe from sumo culture; yudofu from Kyoto temple culture
Nabe (鍋, hot pot) cooking — communal simmering of ingredients in a broth at the table — is Japan's definitive winter cooking tradition, representing the intersection of food, warmth, and social gathering. While shabu-shabu and sukiyaki are the internationally known nabe forms, Japan's full nabe universe encompasses extraordinary regional diversity. Chankonabe is the famous sumo wrestler's training meal — a protein-dense hot pot developed to provide massive caloric intake for sumo athletes. Historically prepared by sumo stable cooks (chanko-ya), the dish typically combines chicken, fish, tofu, vegetables, and egg in a soy-dashi or salt broth; the rule that chankonabe uses four-legged animals only as protein (not beef or pork — crawling on all fours like a sumo wrestler losing implies defeat) is a cultural food belief. Post-sumo career chankonabe restaurants in Tokyo (Ryogoku) serve this as a restaurant concept. Yudofu is the Kyoto Buddhist opposite: silken tofu cut in blocks, gently simmered in kombu dashi at the table, served with ponzu or goma dare dipping sauce, accompanied by only simple vegetable and seaweed additions. The experience of yudofu at Nanzen-ji or Arashiyama in Kyoto in winter — plain white tofu in clear kombu water, snowfall visible through paper screens, the dipping ponzu cold against warm tofu — is one of Japan's profound simple pleasures. Regional nabe diversity: Ishikari nabe (Hokkaido salmon and potato in miso); Akita Kiritanpo nabe; Fukuoka Mizutaki (chicken nabe with ponzu); Okinawan chicken broth nabe (influenced by Chinese soup culture).
Chankonabe: rich, protein-forward, deeply savoury soy-dashi broth that deepens through the meal; hearty and warming, designed for physical nourishment. Yudofu: extraordinarily delicate — the kombu broth is barely there, allowing the tofu's inherent sweetness and texture to be the entire flavour; the ponzu dipping cold against warm tofu creates a complete flavour world of profound simplicity
{"Chankonabe protein rule: only fish, chicken, and seafood — the sumo tradition of avoiding four-legged proteins","Yudofu broth is kombu dashi only — any seasoning is in the dipping sauce, never in the cooking liquid","Table-cooking protocol: ingredients added in stages by cooking time required; tofu and fish last","The broth enriches throughout the meal as ingredients release their flavour — the later pours of broth are more complex","締め (shime — closer): finishing the remaining broth with rice porridge (zosui), udon, or ramen noodles","Nabe pot selection: earthenware (donabe) retains heat and contributes subtle mineral note; iron is for sukiyaki; ceramic for yudofu"}
{"Ryogoku's chankonabe restaurants serve the authentic version and the history — dining here after watching sumo is the ideal combination","Yudofu at Nanzen-ji temple restaurants (Junsei, Okutan) in winter is a pilgrimage experience — reserve a week in advance","The donabe clay pot soaks in water before first use — this prevents cracking when it encounters heat","Nabe parties at home are one of Japan's most important social food rituals — the tabletop cooking is collective entertainment","Adding sake to chankonabe broth (about 30ml per litre) removes any meat odour and adds body"}
{"Adding all ingredients simultaneously — items with different cooking times require sequential addition (root vegetables first, leafy last)","Overboiling yudofu broth — tofu should be gently warmed not vigorously boiled; vigorous cooking makes it rubbery","Seasoning the chankonabe broth too aggressively at the start — the cooking ingredients release salt and flavour; restraint initially","Not using shime at the end — eating the remaining flavour-concentrated broth as zosui is one of the meal's highlights","Serving winter nabe in summer — nabe is strongly seasonal; the social and temperature ritual requires cold weather"}
