According to the distribution of spores, pollen and algae in the surface sediments, Okinawa Trough may be divided into three palynological regions: 1) Pinus-Quercus-Pteridium palynological region lying between the two slopes of Okinawa Trough, 2) Pintts-Castanopsis-Quercus palynological region lying north of the trough and 3) Pinus-Quercus-Polypodiaceae palynological region lying south of the trough. Comparing the sporo-pollen assemblages of the column sections with each other, five sporo-pollen zones have been distinguished and their ages determined. Four problems about the palynology of the trough sediments have been discussed.
