The Japanese Bullhead Shark has been recorded from shallow, marine waters of Japan, Korea, China and Taiwan. It is recognised by a pattern of broad saddles or bars on the body.

The related Zebra Horn Shark, Heterodontus zebra has narrower dark bars on a very pale body. The Zebra Horn Shark has been recorded from Japan, Korea, China, Vietnam, Indonesia and the north-west shelf of Western Australia.

The Japanese Bullhead Shark in the image was photographed in an aquarium at the Tokyo Metropolitan Central Wholesale Market: Tsukiji Market. Thank you to Dr K. Matsuura and Dr K. Sakamoto for confirming the identification of this species and for their generous assistance at the Tsukiji Market.
