Sasahachi is a takeout shop inside Gransta on the basement floor of Tokyo Station in Marunouchi, Chiyoda City. It sells persimmon leaf sushi, round hand-pressed sushi, and a Tokyo Station-exclusive colored sushi box, with sushi in namul and plum flavors among the varieties. Product photos and samples are on display to make choosing easier, and chopsticks and wet wipes come with the order. Gransta is large, so the shop is hard to find.
