Origin of the saying: When fishermen in Hokkaido, Japan supply sashimi, it is difficult to distinguish the types of the peeled fillets, so they often take some fish skins and stab them with bamboo sticks to facilitate identification.

This bamboo stick and fish skin stuck on the fish fillet was originally called "sashimi", but this method is no longer used, but the name "sashimi" is still preserved. Sashimi refers to things like fish, raw fish, sashimi, etc., and refers to dishes in which fresh fish and shellfish are sliced raw and dipped in seasonings for direct consumption.

sashimi is the most distinctive food in Japanese cuisine. According to records, it became fashionable for Japanese to eat sashimi in the 14th century. At that time, people used the word "Wan" to summarize sashimi and sashimi-like foods.

At that time, "preserved" refers to raw shredded fish and shredded pork, and it can also refer to shredded fish and shredded pork soaked in vinegar. At that time, sashimi was just a cooking technique of "preserved". It was not until the 15th century that soy sauce was introduced to Japan and was widely used that sashimi was gradually dipped in soy sauce.
