Fossil pollen grains of Castaneoideae from Holocene sediments from the southern Sea of Japan (J-3) at a depth of 200–202, 165–167, and 120–122 cm were studied with a scanning electron microscope. Pollen of some extant species of Castaneoideae, native to the region (Castanopsis cuspidata, C. sclerophylla, and Lithocarpus glaber) were also studied. As a result, four types of fossil pollen grains were revealed; type I is identified to species as Castanopsis cuspidata, type II is referred to the genus Castanopsis, type III is assigned to the genus Lithocarpus, and type IV is only identifined to subfamily (Castaneoideae type).
