Tonkatsu (とんかつ or 豚カツ) is one of Japan’s most loved comfort foods. It’s a deep-fried pork cutlet coated in crispy panko breadcrumbs, often served with a mountain of shredded cabbage, white rice, miso soup, and a thick, sweet sauce poured on top. The word ton (豚) means pork, and katsu comes from the English word “cutlet.”
This dish is not just tasty, it’s satisfying, simple, and widely available across Japan, from casual diners and station bento to specialty katsu-ya restaurants.
Loin or Fillet? Two Types of Tonkatsu
When ordering tonkatsu in Japan, you’ll usually be asked to choose between two cuts:
- Rosu-katsu (ロースかつ): Pork loin. This has a little more fat around the edges, giving it a juicy, flavorful bite and crispy texture.
- Hire-katsu (ヒレかつ): Pork fillet. Leaner and more tender, perfect for those who prefer a lighter option.
Both are delicious – it really depends on your personal taste.
Free Refills? Yes, Please
Many tonkatsu restaurants in Japan offer free refills of shredded cabbage, rice, and miso soup. You can eat as much as you like, and it’s common to enjoy multiple helpings. The cabbage is usually served with a light sesame or yuzu dressing, balancing the richness of the fried pork.
Don’t Forget the Karashi
Alongside the tonkatsu sauce, you’ll often find karashi (からし), Japanese mustard. It’s sharp and spicy, and just a small dab gives an extra kick when eaten with the pork. Be careful not to use too much!
Tonkatsu in Other Dishes
Tonkatsu is also used in several popular Japanese meals:
- Katsu Curry (カツカレー): A generous slice of tonkatsu placed on top of Japanese curry and rice. It’s heavy, filling, and a favorite among students and salarymen.
- Katsu Sando (カツサンド): A sandwich made with soft white bread and a thick slice of tonkatsu inside. It’s often found at convenience stores, cafes, or even as part of a bento. Some versions include shredded cabbage and a layer of tonkatsu sauce for extra flavor.
- Katsu Don (かつ丼): A rice bowl with sliced tonkatsu simmered in a sweet soy-based sauce with onion and egg. It’s warm and comforting, often eaten before big exams or important days for “good luck.”
How to Make Tonkatsu at Home
If you want to try making it yourself, you’ll need:
- Pork loin or pork fillet
- Salt and pepper
- Flour
- Beaten eggs
- Panko (Japanese breadcrumbs)
- Oil for frying
Season the pork lightly, then coat it in flour, dip it in egg, and cover it with panko. Heat oil in a deep frying pan to around 170–180°C. Carefully place the pork into the oil and fry until golden brown and cooked through, flipping once. Drain on a wire rack or paper towel.
To check if it’s done, use chopsticks or a skewer – clear juice means it’s ready. Slice and serve immediately while the coating is still crisp.
Why Tonkatsu is Special
Tonkatsu is one of those dishes that feels simple, but every detail matters – the freshness of the meat, the crispiness of the crust, and the balance with the side dishes. Whether you’re eating it at a busy Tokyo lunch spot or making it at home, it always hits the spot.
It’s a great introduction to yoshoku (Western-style Japanese food), and once you try it, you’ll see why it’s stayed popular for more than a century.
