“Sushi means raw fish”

The common belief that sushi means raw fish is a widespread misconception, often leading to confusion about this beloved Japanese dish. Historically, the term "sushi" actually refers to the vinegared rice that serves as its foundation, literally translating to "sour-tasting" or "vinegary rice" due to the traditional fermentation process or the later addition of rice vinegar. The culinary ancestor of sushi originated in Southeast Asia as a method of preserving fish by packing it in fermented rice, where the rice was initially discarded after preserving the fish.

This ancient preservation technique traveled to Japan, where it evolved significantly. By the 14th century, rice vinegar was introduced to shorten the fermentation period, allowing both the fish and rice to be consumed together. The modern form, known as nigiri-zushi—hand-pressed vinegared rice topped with fresh ingredients—was developed in the Edo period around 1824. This innovation, featuring fresh seafood, became incredibly popular and is a major reason why many people today associate sushi primarily with raw fish.

The persistent misconception likely stems from the global popularity of sushi varieties that prominently feature raw fish, such as nigiri and various rolls. Furthermore, the term "sashimi," which specifically refers to thinly sliced raw fish or meat served without rice, is often mistakenly interchanged with sushi. However, the defining characteristic of sushi remains the specially prepared, vinegared rice. Many delicious forms of sushi exist that contain cooked seafood, vegetables, or even no fish at all, demonstrating the versatility and true meaning of this iconic dish.
