Japan has a specific relationship with Western food that no other country has developed in quite the same way, and that produces some of the most specifically interesting food in the world.
The relationship: Japan encountered Western food at a specific moment in its history — the Meiji period of the late nineteenth century — when the government’s deliberate adoption of Western cultural practices included the adoption of Western food, primarily through the specific institutional channels of the military, the schools, and the urban restaurant culture of Tokyo and Osaka. The Western food that entered Japan through these channels was then adapted, modified, and in some cases completely transformed by Japanese cooks working for Japanese consumers with Japanese tastes.
The result of this transformation: a category of Japanese food called yōshoku (洋食 — Western food, or more accurately, Japanese-adapted Western food) that is neither Western in any meaningful sense nor traditionally Japanese, but a specific third thing that belongs entirely to Japan and that has no equivalent in any other food culture.
The most beloved yōshoku dishes — hayashi raisu (hashed beef rice), hambāgu (the Japanese hamburger steak), omuraisu (omelette rice), and the two dishes I want to focus on today: korokke (the Japanese croquette) and the broader katsu (cutlet) tradition — are as specifically Japanese as sushi or ramen. They are simply Japanese in a different direction: outward-facing, historically recent, and deeply embedded in the specific experience of modernity that Japan has been negotiating since the Meiji period.
The Korokke: How a French Croquette Became a Japanese Staple
Korokke (コロッケ) — the Japanese word for croquette, borrowed from the French via English — is one of the most widely eaten foods in Japan, available at virtually every supermarket, every butcher’s shop (where it is typically sold warm, freshly fried, from a small counter in the shop), every convenience store, and many prepared food sections of department store basement floors.
The French croquette that is the korokke’s ancestor: a preparation of béchamel sauce with various fillings, formed into a cylinder or oval, breaded and deep-fried. The French original is rich, creamy, and relatively small — a sophisticated preparation that requires specific technique to achieve the specific runny interior that the best versions have.
The Japanese transformation: the korokke replaced the béchamel sauce interior with mashed potato — a significantly simpler and significantly less expensive base that also happens to be more compatible with the Japanese palate’s preference for the specific slightly sweet, mildly savoury flavour of potato. The typical Japanese korokke contains: mashed potato mixed with ground beef (or sometimes onion-and-potato without meat), seasoned with salt, pepper, and sometimes a small amount of soy sauce, formed into a flat oval, coated in breadcrumbs (panko — the specific Japanese breadcrumb that is coarser and lighter than Western breadcrumbs and produces a significantly crispier fried coating), and deep-fried.
The korokke that a Japanese butcher’s shop sells warm, wrapped in paper, for approximately 100 yen per piece — eaten while walking home from the shop, in the specific hand-warming manner that the warm paper and the warm filling produce — is one of the most specifically Japanese casual food experiences. It is humble, affordable, consistent, and deeply satisfying in the specific way that a warm potato preparation in a crispy coating is always satisfying.
The Varieties: Beyond the Basic Potato
The basic potato korokke is the foundation, but the korokke category has expanded significantly from this base to include a range of specific varieties that reflect both Japanese culinary creativity and specific regional traditions.
Kani korokke (カニコロッケ — crab croquette). A more refined preparation in which the interior is a cream-sauce filling (closer to the French original) containing crab meat. The kani korokke is the korokke of restaurants and department store food halls rather than of the neighbourhood butcher’s shop — it requires significantly more preparation and commands significantly higher prices, but produces a preparation of genuine refinement.
Curry korokke (カレーコロッケ). A korokke filled with Japanese curry — the specific sweet, thick Japanese curry that I described in the curry article — rather than plain mashed potato. The curry korokke is one of the clearest examples of specifically Japanese food flavours being incorporated into a Western food format, and it works remarkably well: the crispy panko coating and the specific flavour-concentrated curry interior produce a combination that is both coherent and entirely novel.
Hokkaido potato korokke. Hokkaido Prefecture, whose specific agricultural conditions produce Japan’s finest potatoes, has developed specific premium korokke using the specific high-starch potato varieties that Hokkaido grows. The Hokkaido potato korokke — made from specific potato varieties including the Kita Akari and the Danshaku — has a specific creamy, rich interior that cheaper potato korokke do not achieve, and represents the upmarket end of the korokke category.
The Katsu Tradition: Japan’s Definitive Cutlet Culture
The katsu (カツ) — the Japanese cutlet, breaded and deep-fried — is the category of yōshoku that has produced the most varied and most deeply embedded family of dishes in Japanese food culture.
The original katsu is, of course, tonkatsu (豚カツ — pork cutlet), which I have written about in a dedicated article and which I will not repeat in detail here. What I want to address in this article is the broader katsu ecosystem — the specific family of dishes that the katsu preparation principle has produced.
Gyūkatsu (牛カツ — beef cutlet). The beef version of tonkatsu — a thick slice of beef, typically sirloin or tenderloin, breaded and deep-fried to a specific state in which the exterior is crispy and golden and the interior is rare to medium-rare. Gyūkatsu is served with a specific dipping sauce (typically a combination of soy sauce and wasabi, or a light ponzu) rather than the Worcestershire-based tonkatsu sauce, because the beef’s specific flavour requires a lighter, more delicate accompaniment than pork’s richer profile.
The specific gyūkatsu restaurant experience: the cutlet is served on a wooden board with a small charcoal grill, and the diner is expected to cook the individual slices of beef further on the charcoal to their preferred doneness. This interactive element — the specific agency of controlling the final cooking of your own meat — is one of the features that has made the gyūkatsu restaurant experience popular with customers who want more participation in their meal than the standard restaurant format provides.
Katsudon (カツ丼 — cutlet rice bowl). One of the great triumphs of Japanese comfort food: a bowl of rice topped with a pork cutlet (tonkatsu) that has been simmered briefly in a sweetened dashi-and-soy broth with onion and egg, producing a specific preparation in which the cutlet’s coating has partly absorbed the broth and the egg is set to a specific slightly-runny consistency that coats the cutlet and the rice with a specific umami-rich binding.
The specific quality of good katsudon is in the balance of its elements: the cutlet should have retained enough of its coating’s crispness that it has textural character, but absorbed enough of the broth that it integrates with the other elements rather than sitting separately on the rice. The egg should be set enough to be coherent but not so fully cooked that it becomes dry. The onion should be softened enough to melt into the preparation without being completely dissolved. Achieving this balance consistently is a specific cooking skill that distinguishes excellent katsudon from adequate katsudon.
Katsu karē (カツカレー — cutlet curry). As I mentioned in the curry article, the combination of tonkatsu and Japanese curry rice is one of the most specifically satisfying combinations in Japanese comfort food. The specific excellence: the tonkatsu sauce is abandoned entirely, because the curry provides all the seasoning and moisture that the crispy cutlet needs, and the combination of the cutlet’s crispness, the sweet-savoury curry sauce, and the plain rice produces the specific three-element harmony that katsu karē enthusiasts consider the ideal expression of both dishes simultaneously.
Menchi Katsu: The Lost Treasure of Yoshoku
Menchi katsu (メンチカツ — from “minced” + “cutlet”) is the specific yōshoku preparation that deserves greater international attention than it typically receives, and that represents one of the most completely successful transformations of a Western food concept into specifically Japanese form.
The preparation: a mixture of minced beef and pork, combined with diced onion, seasoned with salt, pepper, and soy sauce, formed into a thick oval patty, breaded in panko, and deep-fried. The result is the specific combination of the crispy panko exterior and the juicy, flavour-rich minced meat interior — similar in concept to the scotch egg or the Salisbury steak but specifically Japanese in its seasoning, its panko coating, and its specific flavour profile.
Menchi katsu is the specific yōshoku dish most closely associated with the specific nikuya (肉屋 — butcher’s shop) culture of Japanese neighbourhoods — like the korokke, it is sold warm at the counter of traditional butcher’s shops and represents the specific local food commerce that convenience stores and supermarkets have gradually displaced but not entirely replaced.
What Yoshoku Reveals About Japan
The entire category of yōshoku — from the korokke to the katsudon to the hambāgu — reveals something specific about how Japan relates to the outside world.
Japan has, across its history, repeatedly encountered foreign cultural elements and subjected them to a specific process: absorption, adaptation, and gradual transformation into something specifically Japanese. This process is visible in Buddhism (which arrived from China and became something distinctly Japanese), in Zen garden aesthetics (which arrived from China and became something distinctly Japanese), in the tea ceremony (which arrived from China and became something distinctly Japanese), and in Western food (which arrived from Europe via America and has become something distinctly Japanese).
The yōshoku dishes are not Western food served in Japan. They are Japanese food made with Western ingredients and inspired by Western forms — as specifically Japanese in their cultural logic and their flavour character as any dish in the traditional Japanese kitchen. The korokke sold warm at the neighbourhood butcher’s shop is not a French croquette. The katsudon is not a Western pork cutlet. They are Japanese food, in the specific sense that Japan has claimed them, transformed them, and made them fully its own.
This is one of the most consistently remarkable things about Japanese culture: the specific generosity with which it accepts and absorbs external influences, and the specific creativity with which it transforms those influences into something that is neither the original nor simply derivative, but genuinely new.
