Geographic and vertical distributions of neritic chitons are reviewed from Hokkaido to Kyushu. The species collected from these areas can be divided geographically into two groups. The former group, distributed in Hokkaido and Sanriku regions, is assigned to cold water species-group. The latter, distributed in western coast of Hokkaido and all other areas from Honshu to Kyushu, is assigned to warm water species-group. Therefore, the distributions of the two species groups overlap along the western coast of Hokkaido and in Sanriku region. Each group is further divisible into two subgroups respectively. Vertical distribution of the species are examined and three subdivisions of intertidal zone plus two deeper divisions are recognized.
