They are my favorite ice creams which are sold at Jomon Ice (縄文アイス) in Mukaihara, a town in the northern part of Hiroshima. This ice cream shop is famous for its unique ice cream which is called "Jomon". (They also have many flavors of ice cream. Green tea, Roasted green tea, Mango, Strawberry... )
Wild rice is in the "Jomon ice cream". The rice is crunchy and so delicious. "Jomon" is the most popular flavor in this shop.
