Onigiri (お握り) is a
Japanese rice ball snack most commonly sold in triangular form and wrapped in
seaweed (
nori).
Writings dating back as far as 1600s tell us that many
Shoguns stored the rice balls in their pockets as a lunchtime meal when at war.
In Japan every
convienence store[?] is stocking
Onigiri in many popular flavors. Specialized shops, called Onigiri-ya, offer handmade rice balls for take out.
