神宮茶屋
There are two famous shops within Hokkaido Jingu. One is the Jingu Chaya, which mainly sells red bean mochi and fukubiki (lucky cakes). The red bean mochi should be eaten fresh as it doesn't keep well, while the fukubiki is made to order and cooked under extremely high heat, resulting in a crispy outer shell paired with rich red bean filling. The unique texture brings a sense of fortune when eaten, and there are also other popular souvenirs and ice cream available.
The other shop is a branch of the well-known Rokkatte in Hokkaido, which is also comfortable, clean, bright, and great for photos. They offer "shimpan" (wagashi made from buckwheat flour filled with red bean paste) and some limited edition souvenirs available for purchase. Many other items can be found at various airports, so there's no need to buy them here, but both shops are definitely worth a visit.
