Introduction
If you love Japanese foods, chances are you’ve come across sushi and onigiri at some point. But here’s a question that has puzzled many: What’s the difference between sushi and onigiri?
They both involve rice, they both can contain fish, and they’re both incredibly delicious! So why aren’t they the same thing?

If you’ve ever grabbed a triangle-shaped rice ball thinking it was sushi, only to take a bite and realize there’s no vinegar in the rice, you’re not alone!
Let’s clear up the confusion once and for all and explore what truly sets these two iconic Japanese foods apart. Spoiler alert: one is much easier to make at home!
What Is Onigiri (Japanese Rice Balls)?

Onigiri, also known as rice balls, is one of Japan’s most beloved comfort foods. It’s simple, convenient, and perfect for on-the-go meals.
Unlike sushi, which uses seasoned rice, onigiri is made with plain rice and often wrapped in nori (seaweed).
These little rice wonders can be filled with anything from savory tuna mayo to pickled plum (umeboshi) or even grilled salmon.
Popular Types of Onigiri

- Shio Onigiri – The most basic version, just rice with a pinch of salt.
- Tuna Mayo Onigiri – A fan favorite, featuring a creamy tuna and mayo filling.
- Umeboshi Onigiri – Stuffed with a tart and salty pickled plum.
- Yaki Onigiri – Grilled rice balls coated with soy sauce for extra flavor.
- Okaka Onigiri – Filled with bonito flakes and soy sauce for a smoky, umami taste.
It’s quick to prepare, budget-friendly, and doesn’t require any fancy ingredients.

What Is Sushi?

Sushi, on the other hand, is a culinary art form in Japan. Unlike onigiri, the rice is seasoned with vinegar, sugar, and salt, giving it a slightly tangy flavor.
It also usually includes fresh fish, seafood, or vegetables, making it a popular choice for a light yet satisfying meal.
Common Types of Sushi
- Nigiri – Hand-pressed sushi with a slice of raw fish on top.
- Maki (Roll Sushi) – Rice and filling rolled in seaweed and sliced into bite-sized pieces.
- Temaki – A cone-shaped sushi roll wrapped in seaweed.
- Chirashi – A bowl of sushi rice topped with assorted sashimi and vegetables.
- Inari Sushi – Sushi rice stuffed into sweet, marinated tofu pockets.
Sushi is healthy, full of fresh ingredients, and rich in protein.
While it requires more preparation than onigiri, the variety and visual appeal make it a favorite for special occasions and everyday meals alike.

Frequently Asked Questions
Yes! It is generally a healthy meal option, especially when made with fresh fish, vegetables, and minimal sauces. However, some rolls with mayonnaise-based sauces or fried ingredients can add extra calories.

Not really! Sushi rice requires short-grain or medium-grain Japanese rice because it has the perfect balance of stickiness and fluffiness. Regular rice won’t hold together well for sushi.
