Meiji-era Tokyo, Japan
Tonkatsu
Thick-cut pork loin in panko, deep-fried to a sandcastle-crisp coat — Japan's Western-cuisine import that became more Japanese than any of its sources.
Panko is the dish.
Western breadcrumbs come from oven-baked bread, with all sides crusty. Panko comes from steam-and-electric-current-cooked bread that has no crust at all; the resulting crumbs are long, flat, airy flakes that absorb very little oil and stay shatter-crisp for a long time. A Western-breadcrumbed pork cutlet is a *Wiener schnitzel* and reasonably good. A panko-breadcrumbed cutlet is tonkatsu, and the texture is in a different category.

Tonkatsu
Thick-cut pork loin in panko, deep-fried to a sandcastle-crisp coat — Japan's Western-cuisine import that became more Japanese than any of its sources.
The Western dish Japan adopted hardest. Tonkatsu (literally “pork cutlet”) emerged in the late Meiji era (1890s–1900s) as part of yōshoku — the Westernised home cuisine that grew alongside Japan’s broader modernisation push. Pondu Restaurant in Tokyo’s Ginza claims the 1899 invention. The original was thinly sliced and pan-fried like a Wiener schnitzel; by the 1930s the thicker, deep-fried, panko-coated cutlet had standardised.
The descendants are everywhere. Katsudon — tonkatsu sliced over rice with onions, egg, and broth. Katsu sandwich — between thick milk-bread, the convenience-store and bakery standard. Katsu curry — over rice with Japanese curry sauce. Menchi-katsu — ground meat in the same coating. Each is its own dish; all owe their existence to the original cutlet.
Cabbage, shredded fine.
The traditional accompaniment is a mountain of finely shredded raw white cabbage — the cut on a tonkatsu knife is what separates a craft shop from a fast-food chain. A drizzle of dressing or just the tonkatsu sauce. The cabbage is not a garnish; it's a structural part of the meal, eaten alternately with the cutlet to cut the fat.
