Kizuna Sushi Akihabara is an all-you-can-eat sushi restaurant in Akihabara, Tokyo, serving sushi and side dishes. Orders are placed on a touchpad, including tuna sushi and side dishes. The all-you-can-eat course runs for two hours with ordering allowed for 90 minutes, until 8:30 p.m. The sushi rice portions are large, so eating a lot is difficult even with the all-you-can-eat format.
