Distribution and habitat

C. japonicus is found throughout the northwest Pacific Ocean, including southern Japan, South Korea, and Taiwan. The species was once believed to have been seen around northwest Hawaii; however, it was later discovered that the fish that had been spotted were of the C. zonarcha species. Since the fish is common and is not endangered by any major threats, the IUCN has classified the species as Least Concern. However, in southern Japan, and sometimes Taiwan, the species is commonly sold after being caught by gill nets.

C. japonicus is found almost exclusively along the coast. They are typically seen swimming in areas with seaweed and rocks.
