Katsudon: Japan's Ultimate Pork Cutlet Rice Bowl

Katsudon (カツ丼) is one of Japan's great comfort foods — a hearty rice bowl dish combining a crispy breaded pork cutlet (tonkatsu) with a savory-sweet simmered egg and onion sauce, all served over a generous bowl of steamed rice. The name combines "katsu" (short for tonkatsu) and "don" (short for donburi, meaning bowl).

The classic egg-style katsudon involves a carefully controlled cooking technique: sliced onions are simmered in dashi, soy sauce, and mirin until soft and sweet, then the pre-fried pork cutlet is added and lightly beaten egg is poured around it. The egg is cooked just until semi-set — still slightly runny in the center — before the entire mixture slides over hot rice. Getting this egg consistency right is the mark of a skilled katsudon cook.

Beyond its delicious flavor, katsudon carries cultural significance as a "victory food" (katsu literally means "to win" in Japanese), traditionally eaten by students before important exams and by athletes before competitions.

Japan's regional food culture means katsudon takes distinctly different forms depending on where you are.

• Tokyo / Kanto style (tamago katsudon): The nationally familiar version — pork cutlet simmered with onion and egg in dashi-soy broth. Rich, comforting, and slightly sweet. This is what most people mean when they say "katsudon."
• Fukui style (sosu katsudon): Thin, extra-crispy pork cutlets stacked on rice and drenched in a thick, dark Worcester-style sweet sauce. No egg, no simmering — just pure cutlet and sauce. Fukui people consider this the only true katsudon. A local specialty worth seeking out.
• Nagoya / Aichi style (miso katsudon): The katsudon variation uses Nagoya's famous red miso (hatcho miso) sauce instead of soy-dashi broth, producing a bold, earthy, deeply savory bowl. Similar to miso katsu served on a plate.
• Osaka style: Often features kushikatsu (skewered, breaded, and fried ingredients) repurposed as a bowl topping, or a variation using chicken (chicken katsudon).
• Niigata / Katsujuu style: The broth is specifically made from local soy sauce (koi kuchi shoyu) giving a darker color and stronger umami compared to the lighter Tokyo style.

Katsudon is one of the more achievable Japanese home cooking projects. The key skills are making a good tonkatsu (breaded cutlet) and mastering the egg-simmering technique.

Ingredients (serves 2):

• 2 pork loin cutlets (1.5cm thick)
• Salt, pepper, flour, beaten egg, panko breadcrumbs
• Neutral oil for deep frying
• 1 medium onion, thinly sliced
• 3 large eggs, lightly beaten
• 150ml dashi, 3 tbsp soy sauce, 2 tbsp mirin, 1 tbsp sugar
• 2 bowls hot steamed rice

Method:

1. Pound pork to tenderize, season with salt and pepper
2. Coat in flour, egg wash, panko — press firmly
3. Deep fry at 170°C for 4-5 minutes until golden, rest 2 minutes, slice
4. In a small pan, simmer onion in dashi+soy+mirin until soft (4 min)
5. Add sliced tonkatsu, pour 2/3 of egg around it, cover 45 seconds
6. Add remaining egg, cover 15 seconds (egg should be barely set)
7. Slide over rice immediately

The key is not overcooking the egg — it should be just barely set, almost custardy.

Katsudon is available everywhere from convenience stores to upscale restaurants, but these are the most notable spots:

Tokyo:

• Tonki (目黒): Legendary tonkatsu-ya open since 1939, consistently rated among the best in Tokyo. Expect a queue of 20-40 minutes.
• Maisen (表参道): Upscale tonkatsu in a converted 1920s public bathhouse. Premium black pork katsudon around ¥2,000.
• Butagumi (西麻布): Serious pork enthusiasts only — they list the pig breed for each cutlet, like a fine wine menu. Katsudon from ¥3,000+.

Fukui (for sauce katsudon):

• Yosteya and Yoroiya: Long-established sosu katsudon specialists in Fukui City. The definitive version of this regional style.

Budget options nationwide:

• Matsunoya (松のや): National chain, consistently good katsudon for ¥690–890.
• Katsu Curry chains: CoCo Ichibanya offers katsu curry (the katsu as topping, not a true katsudon but similar satisfaction).
