Maguroya Kurogin Tsukiji Honten is a seafood shop in the Tsukiji market in Tokyo that sells raw tuna sushi and tuna rolls. Customers choose cuts such as kamatoro, chutoro, and akami individually or as a set, and eat non-frozen raw tuna by cut. On a Sunday morning after 8 a.m., the wait was about 15 minutes, and sushi was made continuously so takeout and eating finished in about 10 minutes. The waiting and eating spaces inside the market are very small.
