What is Devil’s Onigiri (Akuma no Onigiri)?
Onigiri is a popular lunch box dish that translates to “rice ball” in English. These rice balls are usually shaped as rounded triangles but can also be spherical or cylindrical.
Devil’s Onigiri is a unique type of rice ball sold exclusively at the Japanese convenience store, “Lawson.” The name is a direct translation of “Akuma no Onigiri” (悪魔のおにぎり) in Japanese.
It was introduced in 2018 and quickly became a hit, with 200,000 units sold in the first four weeks alone. This rice ball is known for its rich flavor and is said to be “devilishly delicious” and “devilishly addictive.”
It is also known for being high in calories. The “devil” label is commonly used in the names of various dishes that are considered a naughty treat.


How I Developed This Recipe
I wanted to make this devil’s rice ball recipe as close as possible to the iconic taste of Lawson’s Akuma no Onigiri.
As a tribute to this much-loved konbini food, I made sure that every stage of the recipe development process was guided by a commitment to authenticity.
I bought the real thing from Lawson’s a bunch of times. This side-by-side comparison makes sure that this copycat recipe not only has the same flavors as the original but also makes it easier for people to make at home.
Why Is There Tanuki On The Package?
Have you noticed the unusual character on the front of the Devil’s Onigiri packaging? Akuma de Tanuki Kun is a Japanese “tanuki” raccoon dog with bat wings and devil’s horns.
You might think it’s random, but Japanese characters usually have some meaning behind them.

Did you know that there are two famous Japanese dishes with “tanuki” in their names? They are Tanuki Udon and Tanuki Soba. These are noodle dishes topped with tempura flakes.
Without a doubt, the main ingredient for Devil’s Onigiri is also tempura flakes, and that’s why a tanuki raccoon dog became the mascot for this onigiri!

In a large mixing bowl, combine the tempura flakes, aonori powder, soy sauce, sugar, dashi granules, toasted sesame oil and chicken bouillon powder. Stir until all the liquid is absorbed.

Don’t worry if tenkasu loses its crispiness, as it’s supposed to be a little soft by the end.

Introduce the cooked Japanese short-grain rice to the mixture. Mix thoroughly, ensuring the ingredients are evenly distributed throughout the rice.
Divide the seasoned rice into equal portions before shaping to ensure they are all the same size! My recipe makes 4 based on the size of my relatively small rice ball mold, so you can make them bigger or smaller depending on preference.

I really recommend using a rice ball mold for this, as the rice is oily and hard to shape by hand.
Shaping an onigiri rice ball can be done using several methods. You can use cold and wet hands, wrap them in plastic, or use a mold. Whatever your chosen method, pressing the rice down firmly is essential for it to maintain its shape.
In conclusion, shaping an onigiri requires practice. In my post titled “3 ways to shape the perfect onigiri rice ball“, you can learn more about each method for shaping an onigiri.

Notes
- Best eaten immediately. Rice balls for bento boxes should be wrapped with plastic wrap to prevent them from drying out and stored with an ice pack to keep them cool.
- For storage, wrap individually in plastic wrap and store in a sealed container in the freezer for up to 1 month. Microwave to defrost.
- Refrigeration is not recommended.
These were a hit amongst my friends. I will be making these again. (I’m actually making them right now)
