In general, sushi is considered as the rice hardened into a mass and put on fish. It was kind of new food developed in Edo period. First, there was Nara-zhshi which fish meat fermented in rice and only the fish meat was eaten after discarding the rice. After then, rice and fish were fermented and eaten together, which is Nama-Nara-zushi.
Since rice vinegar, the landmark in sushi making, has been used, the variety of sushi has no limit. It is developed by Japanese and representative foods of Japan today. However, its origin, Nara-zhshi is found in China, Korea, and East Asia. Therefor, it is universal stored food eaten by not only Japanese, but also all Asians.
Many studies have assumed that it is originated in Southeast Asia and transmitted to China and later to Korea and Japan. In the east coast of Korea facing Japan and closest area, similar types of food Sikhea is found. Also, some say that the word sushi is originated from Korean shinbap. Therefore, it is possible that sushi is transmitted from Korea to Japan.
