Molluscan larval shells are described from the upper Carboniferous (Moscovian) Ichinotani Formation at Fukuji, Okuhida-onsen-gou, Takayama City, Gifu Prefecture, Japan. The vast majority of these larval shells are isolated and not metamorphosed. The larvae appear to represent species with planktotrophic larval development representing pseudozygopleurid, streptacidid and indeterminate gastropods and pteriomorph and anomalodesmacean bivalves. This is the first report of isolated molluscan larval shells from Palaeozoic deposits in Japan.
