Narezushi appears in the Chinese dictionary in the 2nd century CE as the character sa (鮓, pickled fish with salt and rice), which was during a period in which the Han Chinese were expanding south of the Yangtze river, adopting the food from the non-Han peoples.

The Japanese preferred to eat fish with rice, known as namanare or namanari (生成, なまなれ, なまなり, semi-fermented). During the Muromachi period namanare was the most popular type of sushi. Namanare was partly raw fish wrapped in rice, consumed fresh, before it changed flavor. This new way of consuming fish was no longer a form of preservation but rather a new dish in Japanese cuisine.

During the Edo period, a third type of sushi was developed, haya-zushi (早寿司, 早ずし, fast sushi). Haya-zushi was assembled so that both rice and fish could be consumed at the same time, and the dish became unique to Japanese culture. It was the first time that rice was not being used for fermentation. Rice was now mixed with vinegar, with fish, vegetables and dried food stuff added. This type of sushi is still very popular today.

Today's style of nigirizushi (握り寿司), consisting of an oblong mound of rice with a slice of fish draped over it, became popular in Edo (contemporary Tokyo) in the 1820s or 1830s. One common story of nigirizushi's origins is of the chef Hanaya Yohei (1799–1858), who invented or perfected the technique in 1824 at his shop in Ryōgoku.After the Great Kanto earthquake in 1923, nigirizushi chefs were displaced from Edo throughout Japan, popularising the dish throughout the country.

The earliest reference to sushi in Japan appeared in 718 in the Yōrō Code (養老律令 Yōrō-ritsuryō). As an example of tax paid by actual items, it is written down as "雑鮨五斗 (about 64 liters of zakonosushi or zatsunosushi?)". However, there is no way to know what this "sushi" was or even how it was pronounced. By the 9th and 10th century "鮨" and "鮓" are read as "sushi"
The smell of narezushi was likely one of the reasons for shortening and eventually skipping the fermentation process. It is commonly described as "a cross between blue cheese, fish, and rice vinegar"
There were three famous sushi restaurants in Edo, Matsunozushi (松之鮨), Yoheizushi (興兵衛鮓), and Kenukizushi (けぬき寿し) but there were thousands more sushi restaurants. They were established in a span of barely twenty years at the start of the 19th century. Nigirizushi was an instant hit and it spread through Edo like wildfire.

After the invention of the sheet form of nori seaweed around 1750, makizushi or norimaki, rice and various ingredients rolled with nori appeared.
