A Brief History of Onigiri
Before we dive into the fillings, let’s take a brief look at the history of onigiri.

These early onigiri were eaten as a snack or used as an offering to the gods. Over time, the fillings and ingredients used in onigiri evolved, but the basic concept remained the same.
Traditional Onigiri Fillings
So, what do people typically put in the middle of onigiri? Here are some traditional fillings that are commonly used:
- Salmon: Salted salmon is a classic onigiri filling that’s both delicious and nutritious. The salmon is usually cured in salt and sugar before being placed inside the rice ball.
- Pickled Plum (Umeboshi): Pickled plum is another popular filling that’s known for its sour and salty flavor. The plum is usually pickled in a mixture of salt, sugar, and vinegar before being used in onigiri.
Other traditional fillings include tuna, chicken, and boiled eggs. These ingredients are often mixed with mayonnaise or soy sauce to add flavor and moisture.

If you plan to store onigiri for an extended period, it’s best to wrap each one individually in plastic wrap or aluminum foil, then place them in a container or bag.
When storing onigiri, it’s also important to keep them away from strong-smelling foods, as the rice can absorb odors easily. If you’re planning to eat the onigiri within a day or two, you can also store them at room temperature, but be sure to keep them away from direct sunlight and heat.

When you’re ready to eat the onigiri, simply thaw them at room temperature, then fill with your desired ingredients. Note that freezing onigiri can cause the rice to become slightly dry, so it’s best to use them within a few months for optimal flavor and texture.
Are Onigiri healthy?
Onigiri can be a healthy snack option, depending on the fillings used. Japanese short-grain rice is a good source of carbohydrates, and many fillings, such as tuna and salmon, are rich in protein and omega-3 fatty acids. However, some fillings, such as pickled plum, can be high in sodium.

When eating onigiri with your hands, it’s also customary to use a napkin or other cloth to wipe your hands clean. This is especially important if you’re eating onigiri with fillings that can be messy, such as tuna or salmon.
