Onigiri, or a rice ball, is something every Japanese eats. This Onigiri is a sample in front of the Furikake shop inside Seibu Department Store. Furikake (pronounced furry-cah-kay) is seasoning that we sprinkle on top of rice.
There are a lot of different types of seasoning made from fish, seaweed, eggs, etc. My favorite is the Ume Furikake, which is made from dried plums.
