We performed pollen and tephra analyses and radiocarbon dating measurement on sedimentary drilling cores in Harukoyachi Mire (460m a. s. l.), Iwate Prefecture, northeast Japan. These cores included Akitakomagatake-Yanagisawa pumice, Akitakomagatake-Horikiri pumice, Towada-a volcanic ash, and Iwate-Kariya scoria. The local vegetation changes around the site since ca. 13, 000cal yrs BP were reconstructed as follows: Betula forest mixed with cool temperate broad-leaved forest in ca. 13.4-13.0ka; transitional forest from Betula forest to cool temperate broad-leaved forest in ca. 13.0-10.5ka; cool temperate broad-leaved forest composed mainly of Quercus subgen. Lepidobalanus in ca. 10.5-1.4ka; cool temperate broad-leaved forest and Cryptomeria japonica forest in ca. 1.4-0.2ka; and Pinus densiflora secondary forest and Cryptomeria japonica plantation forest in ca. 0.2ka-present. These vegetation changes indicate that the climate in this region was cool in ca. 13.0ka, followed by an abrupt increase in temperature during ca.13.0-10.5ka, and finally warm similar to the present.
