Sushi is a traditional Japanese food. In ancient Japan, sushi was salted fish marinated with salt and rice, which later evolved into sushi today.
In 700 AD, that is, the Nara era, the Japanese at that time used some vinegar-marinated rice balls, plus some seafood or meat, pressed into small pieces and arranged neatly in a small wooden box as food along the way. In the era of Kamakura shogunate, sushi began to spread widely in Japan and lasted for a long time, becoming an ordinary and delicious food. It is welcomed by people.
So sushi is a kind of lunch box that can be eaten without heating.
