This marine species occurs off Korea, Japan and Taiwan.
The ground color of the shell is white. The outer whorl has two rows of brown blotches among rows of fine spots. The pattern is similar to that of Babylonia zeylanica and B. spirata, but B. japonica has smaller and more numerous spots.
In life, this shell is covered by a brown or tan periostracum.
Although this species is generally considered edible for humans, it is known to bioaccumulate toxins under certain conditions, namely the surugatoxin family, which causes blockage of autonomic ganglia, and tetrodotoxin (pufferfish toxin).
