In the northern floor of the Hakone old caldera, we recognized three widespread tephra layers (Kawagodaira tephra : KwP, Kikai-Akahoya tephra : K-Ah, Aira-Tn tephra : AT), four fallout scoria layers from Fuji volcano (Fuji S-18 tephra : S-18,Fuji-Zunasawa tephra : Zu, Fuji S-11,10 tephras : S-11,10) and six pyroclastic flow deposits from Kamiyama central cone (Hakone-Kanmurigatake tephra : Hk-Kn, Hakone-Kamiyama 5〜1 tephra : Hk-Km5〜1). Four pyroclastic flow deposits (Hk-Kn, Hk-Km5,Hk-Km3,Hk-Km1) overflowed the caldera floor into the western slope of the old somma. AMS-^<14>C ages of charcoal fragments in Hk-Kn, Hk-Km5 and Hk-Km3 are obtained as ca.2.8ka, ca.7ka and ca. 22ka, respectively. Based on AMS-^<14>C dates and tephra-stratigraphy, this study revealed that Hk-Km5 distributes widely on the western slope of the old somma of the Hakone volcano.
