The climatic change during the Late Pleistocene in Central Japan is characterized as follows.(1) Palaeoclimate during the Last Interglacial Epoch is supported as warm and moist, because of that the Fagus pollen content is high rate in sediment.(2) At the early stage of the Last Glacial Epoch, coniferous forest of the subarctic zone had been extended. So that climate during the Last Glacial Epoch is estimated as considerable cold. And it is large possibility that the Japanese Island had been connected to the continent by land-bridge.(3) During the middle stage of the Last Glacial Epoch, it is a transgression stage (=warm period) forming of Atsuta Tarrace in Nobi Plain. Fagus had been increased even in inland basin.(4) During the next cold stage, it is large possibility that the first glacier had been formed on the Central Alps (Kiso Range).(5) During the cold climatic stage of the end of Last Glacial Epoch, the coniferous forest of the sudarctic zone had been extented widely.
