The history of sushi began with paddy fields, where fish was fermented with vinegar, salt and rice, after which the rice was discarded. The earliest form of the dish, today referred to as narezushi, was created in Japan around the Yayoi period. In the Muromachi period (1336–1573), people began to eat the rice as well as the fish. During the Edo period (1603–1867), vinegar rather than fermented rice began to be used. The dish has become a form of food strongly associated with Japanese culture.
Funazushi is a typical type of nare-zushi, an ancient Japanese type of sushi. It is a local dish of Shiga Prefecture, where it has been made since ancient times using Lake Biwa's nigorobuna and other fish as the main ingredients.
