What it is

Founded in 1958 in Kawasaki, Tonkatsu Wako (operated by Wako Commercial Co., Ltd. / Wako Group) is one of the most respected pillars of Japanese tonkatsu culture with more than 250 locations across Japan. Wako holds a revered place in Japanese culinary history as the visionary pioneer that first introduced the concept of *"Unlimited Free Refills of Steamed Rice, Shredded Cabbage, and Miso Soup" (Gohan, Kyabetsu, Misoshiru Okawari Jiyū) to the restaurant industry. Its cutlets are coated in freshly shaved breadcrumbs and deep-fried in pure vegetable oil to golden perfection. Uniquely, Wako serves savory miso soup brewed with fresh brackish-water clams (shijimi*), whose deep umami and liver-nourishing properties are legendary. Strategically positioned at major international airport terminals and shinkansen hubs, it is an essential dining destination upon landing in or departing from Japan.

How to order

Dining at Tonkatsu Wako follows an effortless full-service routine:

Be seated by the host: Walk in and wait at the entrance. Staff will greet you and guide you to an open dining table or booth.
Browse the multilingual menu: Examine the photo-illustrated menu (available in English, Chinese, Korean, and Thai).
*Order your cutlet set meal (Gohan): Choose your cutlet style—such as lean, tender pork fillet (Hirekatsu), rich marbled pork loin (Rosukatsu), or seafood combination platters. During weekday daytime, look for the value lunch set (Wako Gohan*).
Enjoy your complete set meal: Your meal arrives on a lacquer tray featuring your golden cutlet on a metal draining grate, a bowl of hot steamed Japanese rice, a bowl of shijimi clam miso soup, crisp shredded cabbage, and Japanese pickles (tsukemono).
Season to taste: Drizzle Wako's sweet-savory tonkatsu sauce over the pork cutlet, add a dab of hot yellow mustard (karashi), and pour Wako's signature refreshing citrus Yuzu dressing (Tokusei Yuzu Dressing) over your shredded cabbage.
Request free refills anytime: Whenever you finish your rice, cabbage, or clam miso soup, simply catch your server's attention and say "Okawari kudasai" (or point to your empty bowl). Staff will promptly bring hot refills at zero extra cost.
Pay at the front register: When finished (no tipping is required in Japan), take the paper bill slip left at your table to the register near the front door to pay.

Good to know / Common mistakes

Not knowing the miso soup is refillable: Many travelers realize cabbage and rice can be refilled, but assume miso soup is limited to one bowl. At Wako, the delicious shijimi clam miso soup is 100% refillable—just ask!
Throwing away the clams: The miniature shijimi clams inside your miso soup bowl can be eaten using your chopsticks to pluck the tender meat from the tiny shells.
Missing the weekday lunch deal: If you visit on a weekday before 15:00 or 16:00 (hours vary by store), the Wako Gohan lunch set offers incredible value at around ¥1,050 for a full pork cutlet set with unlimited refills.
Tipping the staff: Tipping is never accepted in Japan. Settle the exact amount printed on your table receipt at the cashier counter.
