Onigiri (also referred to as omusubi or rice ball in English) literally translates to “firmly hold.” The word describes the procedure of making an onigiri which is by grasping rice firmly to make a rice ball. The standard form of onigiri that originated in 1885 Japan, contains a handful of plain short grain rice filled with pickled Japanese plum (ume) wrapped in dried seaweed. Modernized versions of onigiri vary in rice mixture, shapes, sizes, fillings and wrappings. In Japan, onigiri is a lunchbox staple much like the sandwich is to the western world.
