Ariso Sushi is a standing sushi counter inside Gransta Tokyo, within the ticket gates of Tokyo Station. It serves natural fish from regions across the country and natural honmaguro, with a three-piece honmaguro set of akami, chutoro and otoro as the main item. Orders are placed on a tablet and the chefs hand each piece over the counter, and the shop tends to be quiet after 9 pm on weekdays. Pieces are priced individually, so a large order adds up.
