Onigiri Bongo
This onigiri (rice ball) specialty shop is set up with counter seats, much like a sushi restaurant. Each onigiri is made to order, so you get freshly-made onigiri with crisp nori and warm rice. Their large onigiri, which are packed with plenty of fillings, are very popular.
Koshihikari rice really is something special. If you love rice balls, you definitely shouldn't miss this place.
