How many types of sushi are there?
There are about 10–12 main traditional forms — but the bigger surprise is the definition. Sushi is the rice, not the fish. The word refers to the vinegared rice, which is why a fish-free cucumber roll is sushi and a plate of pure raw salmon is not.
Sushi or not? The one-rule test
There's a single test: does it have vinegared rice? Yes → sushi. No → not sushi, however much fish it has. Tap any dish.

SUSHI ✓A pressed mound of vinegared rice with a slice of fish on top. Rice present → sushi.
Ten core forms — chefs spin endless rolls from them, but every one is just rice, a wrap, and a topping rearranged.

It's all about the rice
The word sushi comes from an old form meaning "sour-tasting," and it refers to sumeshi — rice seasoned with vinegar, sugar and salt. That single fact resolves most of the confusion: a roll with no fish at all, like cucumber or avocado, is fully sushi, while a beautiful plate of sliced raw fish with no rice is sashimi, a separate category entirely. If you remember one thing, remember the rice is the sushi.
From preservation to fine dining
Sushi began as a way to keep fish from spoiling. In ancient Southeast Asia, fish was packed in salt and fermenting rice for months; when it was time to eat, the soured rice was thrown away and only the preserved fish eaten. That style, narezushi, travelled to Japan and slowly evolved. In the Edo period (today's Tokyo), chefs began serving fresh fish over lightly soured rice as a quick street snack — the fast-food ancestor of modern nigiri.
The East–West divide
Traditional Japanese sushi is minimalist — its whole point is the quality of the fish and the temperature of the rice. The West popularised the uramaki (inside-out) roll: the California roll hid the nori on the inside, and rolls loaded with mayonnaise, cream cheese and avocado were built for palates new to seaweed and raw fish. Both are "real" sushi by the rice rule; they just sit at opposite ends of the same tradition.

The famous things that aren't sushi
Two regulars trip people up. Sashimi is sliced raw fish with no rice — so, by definition, not sushi. Onigiri, the triangular rice ball, looks the part but uses plain salted rice rather than vinegared rice, which also leaves it outside the line. The rice test is strict in both directions: no rice, or the wrong rice, and it isn't sushi no matter how Japanese or how fishy it looks.
A few things people get wrong
Most "wasabi" served outside Japan is dyed horseradish — real wasabi root is hard and costly to grow. Raw salmon sushi is a modern invention: Japan historically avoided raw Pacific salmon over parasite fears, and it only entered the sushi canon after a 1980s Norwegian campaign introduced parasite-free farmed Atlantic salmon. And the pickled ginger and wasabi weren't always garnishes — before refrigeration their antibacterial properties helped make raw fish safer to eat.
Frequently asked
How many types of sushi are there?
Around 10 to 12 main traditional forms — nigiri, maki, uramaki, temaki, gunkanmaki, inarizushi, chirashi and oshizushi among them. From those, chefs create a practically countless number of individual rolls by varying the fish, vegetables and sauces.
Is sushi raw fish?
No. Sushi is defined by vinegared rice, not fish. A cucumber or avocado roll with no fish is fully sushi, while a plate of raw fish with no rice is sashimi, not sushi.
What does the word 'sushi' mean?
It comes from an old form meaning 'sour-tasting', referring to the vinegared rice (sumeshi) at the heart of the dish — not the fish on top.
Is sashimi a type of sushi?
No. Sashimi is thinly sliced raw fish or meat served without rice. With no vinegared rice, it falls outside the definition of sushi.
What is the oldest type of sushi?
Narezushi — fish packed in salt and fermenting rice for months to preserve it. Originally the soured rice was discarded and only the fish eaten; the modern nigiri we know emerged much later, in Edo-period Tokyo.
