Unlimited Natural Bluefin Tuna Chutoro Experience at Osusume-ya

The Ultimate Tuna Experience at Osusume-ya

Starting April 13, 2026, Osusume-ya in Kanda and Funabashi will host a limited-time campaign featuring unlimited natural bluefin tuna chutoro. This delectable offering comes as part of a comprehensive course that allows diners to enjoy a plethora of 130 dishes, all for a mere 3,300 JPY. This promotion is set to run until May 18, 2026, welcoming guests every Sunday through Thursday.

What is Chutoro?

Chutoro, located between the rich red meat and the fatty otoro on the bluefin tuna, constitutes roughly 10-20% of the fish, making it a coveted delicacy. This particular cut is known for its ideal balance of fat and flavor, providing a melting texture that seafood lovers find irresistible. The campaign will feature premium quality chutoro sourced directly from expertly selected tuna, allowing diners to enjoy distinctive flavors and aroma in every bite.

A Unique Selling Point: Limited Seafood Auction at Kanda

At the Kanda location, guests can also partake in the limited seafood auction, which showcases bone-in bluefin tuna. This rare delicacy, typically hard to find in regular dining establishments, will be presented whole, allowing diners to enjoy an interactive experience of scraping the meat off the bones with a spoon. This method not only ensures maximum flavor but also transforms the dining event into an engaging experience as guests can customize their bites with accompaniments like green onions and nori.

Enjoy an All-You-Can-Eat Delight

For 3,300 JPY, diners gain access to a buffet-style celebration of 130 unforgettable dishes, encompassing both exquisite seafood and a variety of Kyushu-style pork bone oden. The menu features vibrant seafood options like salmon marinated in salt koji, bluefin tuna, and ikura, paired exquisitely with tender oden items that highlight the rich, savory broth.
