Gransta is a shopping mall on the basement first floor of Tokyo Station that sells boxed meals, snacks, and bread. Chirashi ekiben, Shiretoko Factory's Tokyo Station limited doughnuts, and Fromage Terra's baked cupcakes are listed as its representative foods. At the basement baggage checkroom, multiple suitcases can be left at once and it is used by the day like coin lockers. Even on weekdays there are many people, making it difficult to find a route through.
