(1) We examined the deposits of the Shimosueyoshi Stage in Kuninaka Plain (Sado Island) and Takada Plain in Niigata Prefecture in the light of pollen analysis and deduced the paleoclimate of that stage.
(2) Paleoclimatic changes in the days of deposition are supposed to have been warm→cool or cool→warm in the Kuninaka Plain and warm→cool→warm→cool or cool→warm→cool→warm in the Takada Plain.
(3) It may be said that the paleoclimate during deposition of each formation differed not greatly from the present climate.
