How To Make Onigir

Onigiri, also known as Japanese rice ball is a great example of how inventive Japanese cuisine can be. It is also a Japanese comfort food made from steamed rice formed into the typical triangular, ball, or cylinder shapes and usually wrapped with nori (dried seaweed).

Various Fillings for Onigiri (Japanese Rice Balls)

Because of its popularity in Japan, all different appetizing flavors/fillings of onigiri can be found in Japanese convenience stores. You can even buy onigiri from speciality stores for take out.

At the time onigiri were first invented, refrigerators didn’t exist yet. So the Japanese came up with a method to keep the rice fresh longer by filling it with salty or sour ingredient as natural preservatives. That’s why salt is rubbed on hands when you make onigiri so that rice is kept safe for a longer time.

The most common fillings for onigiri in Japan include:

  • sha-ke (salted salmon)

  • umeboshi (Japanese pickled plum)

  • okaka (bonito flakes moisten with soy sauce)

  • kombu (simmered kombu seaweed)

  • tuna mayo (canned tuna with Japanese mayonnaise)

  • tarako (salted cod roe) – not in the picture

Nowadays onigiri fillings and flavors are more creative! It is an inventive way to use up any leftovers from previous dinner like Chicken Karaage and Shrimp Tempura. Some onigiri also use mixed rice Takikomi Gohan instead of plain white rice.

Formed into a compact form, these little rice balls make rice portable and easy to eat with hands.

You can enjoy onigiri for a quick snack, or as school/ work lunch or picnic food. They are also commonly included into bento boxes.
