Synopsis A total of 17 species from 12 families of mollusks, comprising of 12 gastropod species from 9 families and 5 bivalve species from 3 families were found around the Nara Campus of Kinki University.

The maintenance of a well-managed natural paddy field environment without concrete could be an important factor for the conservation of freshwater mollusks.
