Toyosu Market is a seafood market in Toyosu, Tokyo, reached by the Yurikamome line. The third-floor restaurant area serves kaisendon and grilled mackerel, and the second floor has shops for simple items such as skewers. The tuna auction starts at 5 a.m., and deck viewing is assigned by lottery about a month in advance. On weekends the restaurant area is cramped with long waits, which makes eating there inconvenient.
