The TV anime Mr. Osomatsu and Okinawan steakhouse chain Yappari Steak have teamed up for a collaboration campaign that began at select locations on May 18, 2026. Starting June 6 (Saturday), the collaboration expands to all Yappari Steak stores nationwide, with each region offering its own unique special menu.
Exclusive Illustrated Coasters
For this collaboration, a special set of drawn-down illustrations was created featuring the six brothers dressed in Yappari Steak staff uniforms — a collaboration-exclusive design. One coaster will be gifted with every collaboration menu item ordered.
Region-Specific Collaboration Menus
Each area has a different collaboration menu, so the experience varies depending on which store you visit.
Hokkaido / Tohoku / Hokuriku / Koshinetsu Area
Kanto Area
Tokai Area
Kinki Area
Chugoku / Shikoku Area
Kyushu Area
Okinawa Area
Note: The flags included with light collaboration food menus feature a group design only — not individual character flags.

About TV Anime "Mr. Osomatsu"
Launched in 2015 to commemorate the 80th birthday of manga artist Fujio Akatsuka, Mr. Osomatsu is based on the classic gag manga Osomatsu-kun and follows the six brothers as adults in their 20s. Hapless, NEET, and socially stunted — yet impossible to dislike — the brothers' unpredictable daily lives earned them the title of Japan's most famous sextuplets.
This year marks the 10th anniversary of the series. A live-action film, Mr. Osomatsu: Operation Human Losers!!!!!?, is also set to open in June 2026.
