Summary:This paper describes the pollen morphology of Cathaya from well-dated Mio-Pliocene sediments in the Himi area of Toyama Prefecture in central Japan. The geological distribution of the genus shows that it was present around the study area and in northern Japan from at least the Middle Miocene to the Early Pleistocene. The genus flourished in the Early Pliocene when the climate was warm, and became extinct in Japan in or after the Early Pleistocene because of climatic deterioration.
