Sushi has been around for a surprisingly long period of time, although not in its present form. The history of sushi is an interesting tale of the evolution of a simple dish. What was to become sushi was first mentioned in China in the second century A.D. Originally, sushi arose out of a way of preserving food. Fish was placed in rice and allowed to ferment, which allowed an individual to keep the fish edible for some time. The rice was thrown away and the fish was eaten when needed or wanted. The method spread throughout China and by the seventh century, had made its way to Japan, where seafood has historically been a staple. The Japanese, however, took the concept further and began to eat the rice with the fish. Originally, the dish was prepared in much the same manner. In the early 17th century, however, Matsumoto Yoshiichi of Edo (now Tokyo) starting seasoning the rice with rice wine vinegar while making his ‘sushi’ for sale. This allowed the dish to be eaten immediately, instead of waiting the months it might normally take to prepare the ‘sushi.’ - See more at: http://www.sushifaq.com/basic-sushi-experience-information/the-history-of-sushi/#sthash.ZA9pXauL.dpuf
