    We investigated vegetation history by pollen analysis on pond and ditchsediments at the Yohfuku-ji-ato Site. Our finding show that: 1) Before the erection (A. D. 1192) of the Yohfuku temple, the surrounding vegetation was characterized by high frequencies of Cryptomeria, Quercus subgen. Cyclobalanopsis and Castanopsis-Pasania. 2) The period after the erection of the Yohfuku temple, from the end of the 12th c. to the end of the 13th c. was similar to the first period. 3) From the end of the 13th c. to the beginning of the 15th c. was distinguished by lower frequencies of Cryptomeria, Cyclobalanopsis and CastanopsisPasania, and the dominance of Pinus subgen. Diploxylon. 4) From the beginning of the 15th c. to the beginning of the 18th c., Diploxylon still was dominant, but frequencies of Quercus subgen. Lepidobalanus gradually increased. 5) The beginning of the 18th c. was characterized by an increase of Cryptomeria. Thus vegetation changed from Cryptomeria, Cyclobalanopsis and Castanopsis-Pasania to Diploxylon at the end of the 13th c. We concluded that the primary factors were the use of Cryptomeria japonica wood and vegetational destruction as Kamakura grew.
