Sashimi is raw fish. When serving sashimi, fishermen in Hokkaido, Japan, 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 the name "sashimi" was still preserved although this method was no longer used.

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 originated from many places in the world. In ancient Japan, fishing and hunting were combined with farming culture, and there was a traditional habit of eating raw food. Biography of Dongyi-Biography of Japan recorded that Japanese people ate seafood, namely sashimi. Sashimi was a common fish dish in ancient China, but it gradually disappeared in ancient times, probably because it was made of freshwater fish. Generally, freshwater fish have more parasites than marine fish.
