Vegetation history was reconstructed from pollen analysis and 14C dates of almost continuous drilling cores obtained from two inland basins, Kenbuchi Basin in north Hokkaido and Furano Basin in central Hokkaido, north Japan. During the 25, 000-32, 000yrs BP vegetation was a boreal conifer forest, so-called “Taiga” mainly composed of spruce (Picea jezoensis and/or P. glehnii), in both basins. Between 16, 000 and 25, 000yrs BP, steppe with open pine (Pinus pumila)-larch (Larix gmelini) forest developed in Kenbuchi Basin, and “Taiga” composed mainly of pine and larch developed in Furano Basin under cold/dry climatic condition. The vegetation in the Full Glacial are correlated with that distributed in northernmost Sakhalin at present. After a period in which larch forests decreased, 12, 000-16, 000yrs BP, they remarkably increased in both basins under cold climatic conditions during 10, 000-12, 000yrs BP. The newly identified cold age in Hokkaido, the “Kenbuchi Stadial”, could be correlated to the Younger Dryas Stadial. In 8, 000-10, 000yrs BP, larch decreased and disappeared from Hokkaido. During this interval birch-walnut forests flourished in the area along rivers of the central basin under the influence of increased precipitation. At about 8, 000yrs BP, oak abruptly became dominant in many parts of Hokkaido. Though oak decreased a little at 5, 000yrs BP, it has been the main component of the “Pan-mixed Forest” developed in present-day Hokkaido.
