Onigiri Ryu is a counter-style restaurant in Kitashinchi, Osaka, serving onigiri, oden and alcohol. The onigiri are shaped to order with fillings such as nanban soy-marinated pickles, nyanko sanmai and Kitashinchi tuna mayo, alongside oden and other side dishes. It is run by Tatsuya Yamanaka, a former WBO world minimumweight champion, and the counter surrounds the kitchen where the onigiri are made. There are only 10 counter seats, so seats are unavailable during popular hours.
