Nanaya Aoyama is an ice cream shop in Shibuya, Tokyo, a fair walk from Shibuya Station. It sells matcha ice cream in seven levels of concentration, along with hojicha, black sesame, and chocolate flavors. Orders are placed by choosing ice cream at the shop and paying at the counter inside, and the only seating is six or seven chairs outside. The difference in taste between matcha level 6 and level 7 is not large.
