How a French Veal Dish Transformed Into Japan’s Iconic Crispy Pork Cutlet

In short: Tonkatsu is a cornerstone of Japanese comfort food, but its roots lie in 19th-century European cuisine. Originally adapted from a butter-fried veal dish, this breaded pork staple evolved through the Meiji era to become a beloved yoshoku classic, eventually defining its own distinct identity in the kitchens of Tokyo.

The story of tonkatsu begins in the late 19th century during Japan's Meiji era, as the nation began adopting and adapting Western culinary traditions. The dish traces its lineage to a French preparation involving veal coated in breadcrumbs and pan-fried in butter. By 1899, the Rengatei restaurant in Tokyo began serving a pork variant, which was initially categorized under the broad umbrella of yoshoku, or Western-style Japanese cuisine.

While early versions were simply known as katsuretsu—a Japanese transliteration of the English word cutlet—the modern iteration of tonkatsu emerged with a focus on thicker pork cuts. This specific style gained widespread popularity starting around 1907 and became firmly established as one of the three great yoshoku dishes during the Taishō period. A significant evolution occurred in 1929 in the Okachimachi district of Ueno, where the thicker, deep-fried pork cutlet we recognize today was first sold to the public.

The preparation of tonkatsu is a precise process of layering textures. Chefs typically use pork loin or fillet, seasoning the meat before dredging it in flour, dipping it in egg, and coating it in panko breadcrumbs. Unlike tempura, which uses a light batter, tonkatsu relies on the crunch of panko. Once deep-fried, it is sliced and traditionally served with shredded cabbage, rice, miso soup, and a savory Worcestershire-style sauce. The dish has since inspired numerous variations, from the geisha-friendly katsu-sando sandwich to regional specialties like Nagoya’s miso-based sauce.

Today, the influence of tonkatsu extends far beyond its origins. It has become a versatile foundation for other meals, such as katsudon, where the cutlet is simmered with egg and broth, or katsu curry. While the term katsu is now used to describe various breaded meats, the pork-based tonkatsu remains the definitive standard, representing a unique intersection of global culinary influence and Japanese innovation.
