Where does the Sushi come from?

Sushi likely emerged from southern China or Southeast Asia centuries ago. Freshwater fish inhabiting rice paddies was used to make the earliest type of sushi called nare-zushi, salted fish which was then pickled in a wooden barrel packed with cooked rice. The history of sushi began with paddy fields, where fish was fermented with vinegar, salt and rice, after which the rice was discarded.
