A palynological study was made on the Holocene sedments of Matsuzaki-cho, Shizuoka Prefecture, Japan. The pollen diagram enabled the core sediment structure to be divided into three local fossil pollen assemblage zones, IZM-I, IZM-II and IZM-III, respectively characterized by the high frequencies of Abies and Cryptomeria, by the rapid increase of Castanopsis and the high frequencies of Abies and Cryptomeria, and by the appearance of Quercus (Cyclobalanopsis) and the high frequencies of Castanopsis and Cryptomeria. The stratigraphical sequence of pollen in the core sediments revealed the vegetation to be composed of a warm-temperate coniferous forest stage and a lucidophyllous forest stage. Coniferous forest, mainly composed of Abies, changed into lucidophillous forest 8700 years ago. The lucidophyllous forest of Castanopsis together with Illicium and Daphniphyllum flourished for about 6000 years. The Crytpomeria forest thereafter continued to flourish throughout the Holocene. This may be explained by the location of the survey area in the southwestern part of the Izu Peninsula, the vegetation of this area having been greatly influenced by the ambient warm and rainy oceanic climate during the early Holocene.
