Sushi originates from the practice of preserving fish by fermenting it in rice for months, a tradition which can be traced back to ancient China. It was originated during Tang Dynasty in China, though modern Japanese adopted sushi evolved to have little resemblance to this original Chinese food. The Japanese name "sushi" is written with kanji (Chinese characters) for ancient Chinese dishes which bear little resemblance to today's sushi.
The history of sushi in japan began around the 8th century. The original type of sushi was first developed in southeast asia as a means of preseruing fish in fermented rice.
In the muromachi period(14-16 century), people began to eat the rice as well as the fish.When Tokyo was still known as edo in the early 19th century, Mobile food stalls run by street vendors became popular.During this period nigiri shusi was introduced. Invented by HANAYA YOHEI in Tokyo, Today’s sushi is not fermented and can be eaten with fingers or chopsticks.
Healthy eaters love it because of its low fat and fresh ingredients. Raw fish and seafood varieties have no added oil, because they’ve skipped the cooking process, and all vegetables are left raw. Also, seaweed is dark green vegetable loaded with nutrients and iron.
