In part I of this paper the writer mentioned the recent progress and the present situation of American and European studies on the various problems of Pleistocene climatic changes. In addition, the writer discussed some relating problems in Japan.The ultimate purpose of this paper is to correlate the Pleistocene climatic changes in the Japanese Islands with these changes in North America and Europe, and to establish the chronological time table of the East Asiatic continent. In part II, the writer shall discuss about his glacial-geologic study in the high mountains of Japan, together with the eustatic oscillations of sea level along the coast of the Japanese Islands.The writer is now engaged in the paleolimnological study of Lake Biwa-ko which appeared in Tertiary and has kept lake water throughout the Pleistocene up to the present day. Accordingly, the sediments of Lake Biwa-ko must indicate the whole Pleistocene ecology of the Japanese Islands. The study of the sediments of this lake is, therefore, exceedingly important in order to establish the whole history of the Pleistocene climate of Japan. The study on this ancient lake will be published later on. The writer hopes to discuss the details of his whole study in American or European periodicals in near future.
