Salmon Onigiri (鮭おにぎり, Sake Onigiri) is one of the most popular and traditional Japanese rice balls. Made with fluffy Japanese short-grain rice and a savory filling of salted grilled salmon, it is a favorite in homes, schools, convenience stores, train stations, and bento lunch boxes throughout Japan.

The rich, flaky salmon pairs perfectly with the soft, slightly sticky rice, while a crisp sheet of nori seaweed adds texture and umami. Simple, nutritious, and easy to carry, Salmon Onigiri is an iconic example of Japanese comfort food.

What Is Salmon Onigiri?

Salmon Onigiri is a hand-shaped rice ball filled with grilled salted salmon. Unlike sushi, the rice is not seasoned with vinegar, allowing the natural sweetness of Japanese short-grain rice to complement the savory salmon filling.

Traditionally shaped into triangles, rounds, or cylinders, Salmon Onigiri is wrapped with nori seaweed, making it convenient to hold and eat on the go.

It is commonly enjoyed as breakfast, lunch, a picnic meal, or a satisfying snack.

How to Make Salmon Onigiri

Step 1: Cook the Rice

Rinse the Japanese short-grain rice until the water runs nearly clear.

Cook according to the package instructions.

Allow the rice to cool slightly until warm but still easy to shape.

Step 2: Prepare the Salmon

Sprinkle the salmon fillets with salt.

Let them rest for 10–15 minutes.

Grill over medium heat or bake at 200°C (400°F) for 12–15 minutes, until fully cooked.

Remove the skin and bones.

Flake the salmon into small pieces.

Step 3: Shape the Onigiri

Wet your hands with salted water.

Place a handful of warm rice in your palm.

Make a small indentation in the center.

Add 1–2 tablespoons of flaked salmon.

Cover with more rice.

Gently shape into a triangle, round, or cylinder without pressing too firmly.

Step 4: Wrap with Nori

Wrap the bottom or one side of each rice ball with a strip of nori.

If you prefer crispy nori, wrap it just before serving.

Step 5: Serve

Arrange the Salmon Onigiri on a serving plate.

Sprinkle with sesame seeds or furikake if desired.

Serve immediately or pack into a bento lunch box.
