One of the interesting Japanese snapper facts is that they are an important Japanese delicacy.

The Japanese snapper (Paracaesio caerulea) was formally described in 1934 for the first time as Vegetichthy caeruleus by a Japanese zoologist Masao Katayama. Initially, the snapper locality given was Tokyo Fish Market and was believed to be caught in the vicinity of Hachijo-Jima in the Izu Islands.

The 'caerulea' in their name means 'blue', which is found on the back and side of the fish. In Japanese culture, the Japanese snapper is an important cuisine and is always available in the fish markets.

The fishing for the snapper is done using handlines and bottom longlines and is sold fresh in the market, and served whole.

In Japanese, this fish is also called 'aodai,' and its flesh is used for making sushi and sashimi. It is also prepared as soup with miso, deep-fried, broiled, or sauteed.
