The Origin and Popularity of Akuma no Onigiri
Onigiri, or rice balls, have been a staple in Japanese cuisine for centuries.

The combination of spicy ingredients and the comforting texture of rice has made it a favorite among those who enjoy a bit of heat in their food. Today, you can find Akuma no Onigiri in convenience stores, street food stalls, and even high-end restaurants across Japan.
Ingredients for Akuma no Onigiri
Before we dive into the recipe, let’s gather all the ingredients you’ll need to make Akuma no Onigiri:
- 2 cups of Japanese short-grain rice
- 2 1/4 cups of water
- 1 tablespoon of rice vinegar
- 1/2 teaspoon of salt
- 2 tablespoons of sriracha sauce
- 1 tablespoon of soy sauce
- 1 teaspoon of sesame oil
- 1/2 cup of finely chopped kimchi
- 2 tablespoons of chopped green onions
- 2 sheets of nori, cut into strips
- Optional: sesame seeds for garnish
Step-by-Step Recipe for Akuma no Onigiri
Step 1: Prepare the Rice
Start by rinsing the rice under cold water until the water runs clear. This helps remove excess starch and ensures that the rice cooks evenly. Once rinsed, combine the rice and water in a rice cooker or a pot. If using a rice cooker, follow the manufacturer’s instructions. If using a pot, bring the water to a boil, then reduce the heat to low, cover, and let it simmer for about 15 minutes or until the rice is fully cooked.
Step 2: Season the Rice

While the rice is still warm, transfer it to a large bowl. Add the rice vinegar and salt, and gently mix using a rice paddle or a wooden spoon. Be careful not to mash the rice; you want to keep the grains intact. This step adds a subtle tanginess to the rice and enhances its flavor.
Step 3: Prepare the Spicy Filling
In a separate bowl, combine the sriracha sauce, soy sauce, and sesame oil. Mix well to create a spicy sauce. Add the finely chopped kimchi and chopped green onions to the sauce, and stir until everything is evenly coated. The kimchi adds a satisfying crunch and a complex flavor that complements the spiciness of the sauce.
Step 4: Assemble the Onigiri
Now comes the fun part—assembling the onigiri! Wet your hands with water to prevent the rice from sticking. Take a handful of rice and flatten it into a small disk in your palm. Place about a tablespoon of the spicy filling in the center of the rice disk. Gently fold the edges of the rice around the filling, shaping it into a ball or a triangular form. Repeat this process until all the rice and filling are used up.
Step 5: Wrap and Garnish
Wrap each onigiri with a strip of nori, ensuring that the nori adheres to the rice. The nori not only adds a delightful crunch but also makes it easier to handle the onigiri. If desired, sprinkle sesame seeds on top for an extra layer of flavor and texture.
Tips for Making Perfect Akuma no Onigiri

Here are some tips to help you perfect your Akuma no Onigiri:
- Use Japanese Short-Grain Rice: This type of rice is sticky and holds together well, making it ideal for onigiri.
- Adjust the Spiciness: If you prefer a milder version, reduce the amount of sriracha sauce or kimchi. Conversely, if you love intense heat, feel free to add more.
- Keep Your Hands Wet: Wetting your hands prevents the rice from sticking and makes it easier to shape the onigiri.
- Experiment with Fillings: While the spicy filling is a star, you can also try other fillings such as spicy tuna, spicy mayo, or even a combination of different spicy ingredients.
- Serve Fresh: Onigiri is best enjoyed fresh. If you need to store them, wrap each onigiri individually in plastic wrap to keep them moist.
