Sushi was called NARE sushi in the seventh century AD. It was originally a method of preserving fish.

The fish is marinated in salt and wrapped in rice. After the fish is fermented, the rice produces lactic acid, which soaks the fish to prevent it from spoiling.

In the mid-17th century, people added vinegar to sushi rice, revolutionizing the sushi-making process.

This new method is also called HAYA-SUSHI (egg-wrapped sushi). This kind of sushi can be made in half a day. This is because the acidity in the vinegar speeds up the fermentation time, thus reducing the time for making sushi.

About 200 years later, a sushi chef named Yohei Ya took the art of making sushi to the next level by pressing the sushi with his hands instead of using stones, squeezing it with warm hands so that the fermentation was completed almost immediately.

The methods used to make sushi today are still very similar to those used in Yayohei 200 years ago.
