Originally, onigiri was used as a portable and convenient food for warriors, travelers, and farmers. The rice balls were easy to carry and were often packed with nutritious fillings that could sustain individuals during long trips or hard work in the fields. During the Edo period (17th–19th century), onigiri became popular among ordinary citizens and appeared in various shapes, including triangles, rounds, and even more intricate shapes meant to symbolize animals or objects.
Onigiri’s cultural significance in Japan has only grown, with the dish representing more than just food. It’s a symbol of comfort, home, and family.

Ingredients for Japanese Onigiri
The beauty of onigiri lies in its simplicity, yet there are a few essential ingredients that will make your Japanese onigiri recipe shine. While the core of onigiri is steamed rice, the fillings, seasoning, and wrapping are what truly bring this dish to life.
For the Rice:
- 2 cups short-grain sushi rice (or any sticky rice variety)
- 2 ½ cups water
- 1 tablespoon rice vinegar
- 1 tablespoon sugar
- 1 teaspoon salt
For the Fillings (Choose one or multiple options):
- 2 tablespoons salted salmon flakes (Shiozake)
- 1 tablespoon pickled plums (umeboshi), chopped
- 1 tablespoon tuna mayo filling (canned tuna mixed with Japanese mayo)
- 2 teaspoons seaweed (nori) strips
- 1 tablespoon teriyaki chicken, shredded
For the Nori (Seaweed):
- 4-6 sheets of nori (optional, but recommended for wrapping)
For Seasoning and Garnish:
- Sesame seeds (optional)
- Furikake (Japanese rice seasoning, optional but adds extra flavor)
Step-by-Step Instructions to Make Onigiri
Step 1: Prepare the Rice
Start by rinsing the sushi rice under cold water until the water runs clear. This helps remove excess starch and prevents the rice from becoming too sticky. After rinsing, let the rice soak in the water for about 30 minutes. Then, cook the rice using a rice cooker or on the stovetop. If using a stovetop, bring 2 ½ cups of water to a boil in a saucepan with the soaked rice, then reduce the heat to low and simmer for 15-20 minutes, or until the rice is fully cooked.
Once the rice is done cooking, allow it to sit for about 10 minutes to firm up slightly. In a small bowl, mix the rice vinegar, sugar, and salt. Gently stir this seasoning mixture into the cooked rice. Use a paddle or a wooden spoon to carefully fold the seasoning in, without mashing the rice. Let the seasoned rice cool slightly but still remain warm, as it’s easier to shape when it’s warm.
Step 2: Prepare the Fillings
While the rice is cooling, prepare your desired onigiri fillings. For the salmon flakes, grill or pan-sear the salmon and then flake it into small pieces. You can lightly season it with salt to enhance its flavor. If you are using umeboshi, remove the pit and finely chop the plums. For the tuna mayo filling, drain the canned tuna and mix it with a generous amount of Japanese mayo (or regular mayonnaise). Other options include teriyaki chicken or even seaweed, depending on your personal preference.
Step 3: Shape the Onigiri
With your hands, form a small bowl of rice into a triangle, oval, or round shape. To make a triangle, place your hands in the shape of a triangle and mold the rice gently into place. You want the rice to hold together without being packed too tightly.
Once your rice has been shaped, make a small indentation in the center. Add a spoonful of your chosen filling into the indentation. Carefully fold the edges of the rice over the filling and gently press the rice together to form a compact, uniform shape. Repeat this process for the remaining rice and fillings.
Step 4: Wrap the Onigiri with Nori
Once your onigiri are formed, take a sheet of nori (seaweed) and cut it into strips or smaller squares, depending on how you prefer to wrap your rice balls. Wrap the nori around the base of each onigiri or serve it on the side for those who want to add it themselves. The nori provides an extra layer of flavor and texture that perfectly complements the rice.
Step 5: Garnish and Serve
For added flavor, you can sprinkle your onigiri with a bit of sesame seeds or furikake rice seasoning. These garnishes add texture and additional layers of flavor, from salty to savory, making each bite even more delicious.
Serve the onigiri immediately while the rice is still fresh, or pack them into a bento box for a convenient, portable meal.
Tips and Variations for Onigiri
- Rice Vinegar and Sweetness: If you prefer a milder, less tangy rice, reduce the amount of vinegar and sugar to taste.
- Fillings: The fillings are highly customizable. You can try different combinations of salty, savory, or even sweet fillings to suit your taste.
- Filling Quantity: Be cautious not to overstuff your onigiri, as the rice can break apart if too much filling is used.
- Serving Ideas: Onigiri is traditionally served with miso soup or a side salad for a complete meal.
