Tonkatsu Katsu Curry and Katsu Rice Bowl
Japan — Rengatei restaurant in Ginza, Tokyo, credited with serving Japan's first Western-style breaded pork cutlet in 1899; the dish was called 'katsuretsu' (from 'cutlet') before the abbreviation 'katsu'; tonkatsu as a category established by the 1930s; katsudon emerged as a variant in the Meiji/Taisho era; katsu curry became an international phenomenon from the 1990s
Katsu — the Japanese breaded and fried cutlet tradition centred on pork (tonkatsu), chicken (chicken katsu), and seafood — is one of the defining comfort food categories of modern Japanese cuisine, with a history of barely a century that has created an entirely Japanese culinary tradition from European origins (the Austro-Hungarian Wiener Schnitzel reached Japan via European cooking introduced in the Meiji era) that is now as distinctively Japanese as any washoku preparation. The central technique — double-dredging in flour, beaten egg, and panko breadcrumbs before deep frying — produces a fundamentally different result than Western breadcrumb frying: panko (パン粉 — large, irregular white breadcrumbs produced by baking bread using electrical current rather than conventional ovens, creating a lighter, more airy crumb structure) creates a significantly lighter, crispier, less oil-heavy coating than standard fine breadcrumbs, and this difference in coating texture is the primary reason Japanese katsu is considered superior to European schnitzel by most who have compared them directly. The katsu tradition has branched into several culturally embedded sub-forms: tonkatsu (pork loin or fillet — hire katsu — as the purest form); katsudon (pork cutlet, egg, and onion simmered in dashi-soy sauce and served over rice — Japan's most popular donburi); katsu sando (a specific sandwich form that has achieved global trend status); katsu curry (the most widely consumed format globally through Katsu Curry Houses and chains); and the Nagoya specialty miso katsu (served with thick hatcho miso-based sauce instead of tonkatsu sauce). The three great Tokyo tonkatsu restaurants — Tonki (Meguro), Suzuya (Kanda), and Maisen (Omotesando) — maintain the craft tradition at the highest level, where the quality of the pork (breed, cut, and fat ratio), oil management (changing oil regularly, maintaining temperature precisely), and the classic combination with shredded raw cabbage, tonkatsu sauce, and karashi mustard define the authentic experience.
