Babylonia japonica, common name the Japanese Babylon or Japanese ivory shell, is a species of sea snail, a marine gastropod mollusc in the family Babyloniidae.
The pattern is similar to that of Babylonia zeylanica and B. spirata, but B. japonica has smaller and more numerous spots.
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).
In September 1965 a food poisoning outbreak occurred after ingestion of this species from Suruga Bay.
