Japanese Spicy Tuna Rice Bowl. Warm sushi rice layered with canned tuna, fresh cucumbers, spicy mayo and crunchy nori. An easy budget friendly meal that is so delicious and calls for six ingredients with the star ingredient being canned tuna. This quick rice bowl recipe comes together in less than 10 minutes if you have cooked rice or 30 minutes with uncooked rice. Great for dinner or lunch.

For years, I have been obsessed with the combination of canned tuna, short grain rice, and kewpie mayo with nori. It was my go-to meal when I honestly had no idea what to eat or there was nothing in the fridge, but I wanted something satisfying, delicious and comforting.
The best part about this tuna rice bowl is that it is budget friendly and it’s quick to make in under 10 minutes if you have cold leftover rice in the fridge. Now there are many tuna bowl recipes out there but I haven't seen something super simple. A lot of them contain seared tuna or they're overwhelmed with ingredients. But mine is really simple and easy!
What does it taste like?
The combination of the spicy tuna rice mixture with a piece of crunchy nori reminds me of Korean Tuna Triangle Kimbap or Japanese Onigiri.
Easy to make!
This canned tuna rice bowl is incredibly easy to make at home. As mentioned, you will only need 6 ingredients:
- Canned tuna (in oil is recommend for a delicious bowl), strained of oil and liquids
- Short grain sushi rice, cooked
- Nori
- Fresh cucumbers
- Sriracha Sauce
- Kewpie Mayo (or Japanese Mayo)
First place about 1 ¼ cups of warm cooked rice into a wide bowl. If needed, reheat it in the microwave for 90 seconds, covered.
Over the rice, layer overtop with strained canned tuna. Pile a ½ cup of sliced cucumber over the tuna.
Generously squeeze sufficient sriracha sauce and kewpie mayo over top.
Crush up a sheet of nori with your hands and sprinkle the nori over your rice.
Fold 4-5 sheets of nori into 4 squares and rip or cut along the edges to enjoy with the rice mixture.

How to spice up my rice bowl?
The great thing about this easy tuna rice bowl is that it’s very versatile! If you’re not a fan of cucumbers, replace it with carrots or another crunchy vegetable that you enjoy. Here are some other topping ideas:
- Carrots, sliced into matchsticks
- Avocado
- Sauteed Spinach
- Kimchi
- Pickled yellow daikon radish
- Fried egg
- Furikake seasoning
Warning: this Japanese canned tuna rice bowl is best served with minimal toppings. I wouldn’t suggest overwhelming your bowl with everything I suggested. The beauty of this dish is the simple taste of the tuna mixed with spicy mayo and rice with nori.
Tips for making Spicy Tuna Bowl with Rice
Below are tips on making this homemade spicy tuna bowl:
- I love using canned tuna in olive oil! I find that the tuna is so much more tender and delicious in taste. Yes, the fat content is higher but hey, you only live once.
- Use short grain rice. This rice is highly recommended because it’s stickier and more moist than jasmine rice, especially when you’re scooping some into your nori - you won't want the rice mixture falling all over the place. I also find it tastes better with this combination of ingredients.
- Use Kewpie mayo or Japanese mayo. This mayo is not the same as normal mayo found at western grocers. It’s creamier and has a higher yolk content.
- Keep your cut sheets of nori dry and away from moisture. Any surrounding moisture will be absorbed by nori lessening the crunch of it when you're about to dig in
- Keep your rice bowl simple! You don’t want to overload this rice bowl with too many topping ideas because the beauty of this dish is the simplicity of the tuna with the mayo and rice.
