Why do Japanese people like the custom of eating sashimi?

Japanese traditional food culture believes that "the processing technology of food should be reduced as much as possible and be as close to natural consumption as possible" is the idea of cooking without cooking. The most representative is sashimi (サシミ). Since ancient times, Japanese people have thought sashimi is the best food, so raw fish dishes such as sashimi have long been firmly on the throne of traditional Japanese cuisine. What is the origin of "サシミ" (sashimi)? It can also be written as referring to the body, referring to the taste, and poor taste. Originally known as "Okina Ma Su", it is an impromptu dish prepared by fishermen after slicing fish. In the Heian period, in order to know the name of the fish fillet, the fish fin was inserted into the body like an ornament, so it was called "サシミ", which was also known to the world with the development of soy sauce. Japanese usually order sashimi when they go to izakaya or eat.
