With only 10 seats available at this no nonsense sushi bar, reservations are a must. Located on the ninth floor of Ginza’s Juno building, expect a fairly tame, formal dining experience, as guests are encouraged to focus entirely on the food. Book months in advance for one of the coveted seats and be prepared to dole out a pretty penny for chef Mituzani’s three Michelin-starred sushi. Be warned: There’s a strict cash-only policy.
