Onigiri (rice balls) is rarely (if ever) found in restaurants...It's simply not on the Menu!
It is really an example of store-bought food... or a takeaway choice from one of the many convenience stores found everywhere in Japan:( 7/11 Lawson/ Family Mart.)
Or ... it is homemade and usually eaten as part of a bento box! Made to be eaten on the move as it were... it is very handy and easy to eat without chopsticks or utensils.
Onigiri is usually something we make at home, not have in a restaurant.
Onigiri is a food made at home or bought from the store.
