A huge 3,000-square-meter retail space designed by noted architect Kengo Kuma, this is the largest Starbucks branch in the world, and the fifth in their series of Reserve Roasteries. The centerpiece of the interior is a 17-meter-tall copper cask that rises up through the four levels of the shop and is connected to silos at the individual coffee counters by a series of overhead tubes.

In addition to the usual coffee and dessert drinks, the main counter on the ground floor serves unique coffee-based beverages such as a barrel-aged cold brew, which is made with beans that have been aged in whiskey barrels. There's an Italian-style bakery in one corner producing a wide variety of pastries, savory and dessert tarts, sandwiches and pizzas.

Up on the second floor there's a tea bar, serving 18 loose-leaf teas and various tea-based drinks. The third-floor Arriviamo bar features original coffee- and tea-based cocktails drinks such as the Kaga Salt Caramel Milk Tea (brandy, Hojicha tea, butterscotch espuma foam) as well as wine and beer.
