Onigiri, which is also called omusubi, is kind of Japanese-style-sandwich or -burger.
It's handy, and there are many kinds with different stuff inside.
Onigiri is a rice ball (mostly shaped into a triangle) that includes stuff (such as grilled salmon and
pickled plum) inside and is usually wrapped by dried laver.
If an onigiri has sake(grilled salmon) inside, it's called sake-onigiri.
Many people buy onigiri at convenience stores, and there are even stores which mainly sell onigiri. Each onigiri is about 100 yen($1). Since there was a heigh-class-onigiri boom before, there are still more expensive onigiri using better stuff inside, better rice, and better dried laver.
Also, you'll be amazed by the wrapping device which keeps laver covering onigiri dried until you eat. You shouldn't miss this reasonable and delicious onigiri!
