Tonkatsu is a thick pork cutlet coated in panko (Japanese breadcrumbs) and deep-fried until golden. It is one of Japan’s most universally loved comfort foods, a dish that ranges from quick lunch counters to high-end specialist restaurants, where the pork is sourced from specific heritage breeds and aged for tenderness.
The combination of crispy panko exterior and juicy, seasoned interior makes it one of the most satisfying fried foods in any cuisine.
Quick Answer: Tonkatsu: Breaded deep-fried pork cutlet. Served with shredded cabbage, tonkatsu sauce, rice, and miso soup. Two main cuts: rosu (loin, fattier) and hire (fillet, leaner). Price range: 900 yen at a casual restaurant to 4,000+ yen at a specialist using premium pork. Found at dedicated tonkatsu restaurants (tonkatsu-ya) and at many izakayas and teishoku restaurants. See the what to eat in Japan for the broader Japan food guide.
Types of Tonkatsu
Rosu Katsu (Loin Cutlet)
Made from the pork loin, which has a rim of fat along one edge. The fat renders during frying, adding flavour and moisture. Rosu is generally considered the more flavourful of the two cuts. The fat-to-lean ratio makes it juicy but richer. Most specialists recommend rosu for first-time tonkatsu eaters.
Hire Katsu (Fillet Cutlet)
Made from the pork tenderloin. Leaner and slightly more tender than the loin, with no fat rim. The fillet is the premium cut at most high-end tonkatsu restaurants, prized for its delicacy. Better suited to those who prefer a leaner cut.
Menchi Katsu
A tonkatsu-style preparation using ground pork (or a pork-and-beef mixture) formed into a patty, then breaded and fried. More affordable than cutlet versions and found at casual restaurants and as a street food item (particularly in Yanaka, see Yanaka guide).
Katsu Curry
Tonkatsu is served over rice with Japanese curry sauce. One of Japan’s most popular comfort meal combinations. The curry sauce soaks into the panko coating, giving a different textural experience compared to dry tonkatsu. Available at both tonkatsu restaurants and at dedicated katsu curry chains (CoCo Ichibanya is the largest).
Katsu Sando
Tonkatsu in a white bread sandwich, with tonkatsu sauce and sometimes shredded cabbage. One of Japan’s finest convenience store sandwiches and a staple at specialist sando shops in Tokyo and Osaka. The katsu sando from Maisen (Tokyo) is arguably the most famous single-tonkatsu item in Japan.
How to Eat Tonkatsu
The Sauce
Tonkatsu sauce is a thick, sweet-savoury sauce similar to Worcestershire sauce but more complex. The Bull-Dog brand is the standard. Applied to the cutlet, not the cabbage. At high-end restaurants, various sauces and salts (sesame, mustard, oroshiponzu) may be offered as alternatives.
The Sesame Grinding Ritual
Many tonkatsu restaurants provide whole white sesame seeds and a ceramic mortar at the table. You grind the seeds yourself just before eating, then mix the fresh sesame into the sauce. The aroma of freshly ground sesame with tonkatsu is one of Japan’s most appetizing restaurant experiences.
The Cabbage
A mound of thinly shredded cabbage is served with every tonkatsu meal. This is not a garnish but an essential part of the dish: the cool, fresh crunch of the cabbage refreshes the palate between bites of the rich pork. Free cabbage refills are offered at most tonkatsu restaurants.
Premium Pork Tonkatsu
High-end tonkatsu restaurants source heritage-breed pork for a significantly more complex flavour:
- Kurobuta (Black Berkshire): From Kagoshima (see the Kagoshima guide). The gold standard of Japanese pork is with rich, marbled meat.
- Tokyo X: A Tokyo-bred heritage variety combining several genetic lines for sweetness and tenderness.
- Yuki no Buta (Snow Pork): Raised in Hokkaido (see the Hokkaido guide) on a diet that includes brewery by-products.
Where to Eat Tonkatsu
Tokyo: Maisen (Omotesando), Tonki (Meguro), Butagumi (Nishi-Azabu) for high-end. Tonkatsu Wako chain for reliable mid-range. In Osaka, tonkatsu is available throughout the Namba guide and the Shinsaibashi area. See the Tokyo and Osaka food guides.

FAQ
Is tonkatsu different from schnitzel?
Related but distinct. Schnitzel uses a thinner cut of meat, which is pounded flat and fried in finer breadcrumbs or flour. Tonkatsu uses a thicker cut and panko (larger, coarser Japanese breadcrumbs), creating a crispier, airier coating. The tonkatsu sauce and sesame accompaniments are uniquely Japanese. The overall eating experience is quite different despite the structural similarity.
Is tonkatsu available for non-pork eaters?
Chicken katsu (chikin katsu) uses the same preparation as pork katsu but uses chicken instead of pork and is widely available as an alternative. Fish katsu (saba katsu, using mackerel, is a Kyoto specialty) also exists. See the Japan vegetarian guide for Japan dietary guidance.
What is the difference between tonkatsu and karaage?
Tonkatsu uses panko breadcrumbs on a whole cutlet. Karaage uses potato starch on marinated chicken pieces. Tonkatsu is a formal cutlet dish; karaage is a casual bar/izakaya snack. Both are deep-fried, but the pork vs. chicken, whole cut vs. pieces, and panko vs. starch distinctions yield completely different textures and eating experiences.
