KADOMASU - THE SQUARE BURGER

Located in the Asakusa Nishi-Sando Shopping Street right next to Senso-ji Temple, Kadomasu (角〼) is a specialty Wagyu restaurant where guests can savor expertly selected, artisan-grade A5 Japanese Black Wagyu.

Our signature dish, the Square Burger, is a luxurious creation featuring a juicy 100% A5 Wagyu patty sandwiched between specially crafted toast. The secret to its incredible flavor lies in our meticulous griddle-cooking technique. By melting plenty of rich butter on the piping-hot teppan and gently crisp-grilling the surface as if lightly fried, the bread takes on a fragrant, flaky aroma reminiscent of a fresh croissant. Crispy on the outside, soft and chewy on the inside—this exquisite texture perfectly catches every drop of overflowing Wagyu juices.

The bread is a custom recipe made with 100% Japanese wheat and golden sesame, co-developed with Terasawa, a historic Asakusa bakery founded in 1950. It is paired with our special craft sauce, made with a base from TOKIWA SAUCE—Tokyo’s oldest sauce manufacturer, celebrated for extracting the rich umami of fresh vegetables—ensuring a burst of pure, authentic flavor all the way to the last bite.

The savory aroma of Wagyu and butter wafting from the outdoor grill is another charming highlight, drawing crowds of visitors from around the world each day during their stroll through Asakusa. We also offer a lineup of Japan-inspired drinks and sweets, including our popular Matcha Beer with its rich aroma and delightful hint of bitterness.

Created in collaboration with historic Asakusa purveyors and crafted with relentless attention to ingredients and technique, the Square Burger honors tradition while delivering a fresh culinary experience. It is a true taste of modern Asakusa.
