It is known that Holocene peaty sediments are well developed in incised valleys at Pleistocene uplands in Japan. Those sediments have been studied for reconstruction of paleoenvironment. The author researched Nishi-Mikawa plain in central Japan, and got available sediments in an incised valley of Hekkai Upland. Three samples of the sediments were dated by AMS ^<14>C measurement. The result shows that accumulation of peat started around 3,100yr BP, and peaty silt and clay were deposited since 2,500yr BP. Diatom analysis was done for the samples and its result suggests that the site was affected by flowing water between 2,500 and 1,800yr BP. It is possible that the environmental change which was found in this valley was common throughout Nisi-Mikawa plain.
