Surveys of literatures, archaeological materials and present field observations was made to discover on the archaeological sites of collecting site for pearl oyster from Yayoi to Kofun period. Only on the Tenjin-yama site, Itoshima-shi, Fukuoka pref., several remains of pearl oyster, Pinctada fusca was detected in Yayoi to Kofun period. This Pinctada shells of Tenjin-yama site will be evidence of collecting site for pearl oyster. Another pearl oyster, P. maculata were excavated from some archaeological sites of late Okinawa shell midden age. I will suppose that these sites will be also collecting site for pearl oyster. Historically, Pearl Oyster Castle of Hepu, Guangxi, China and Gulf of Mannar, Sri Lanka were well known to collecting site for pearl oyster, but details of these sites were unknown. In this survey pearl oyster remains were discovered on both sites, species, waste condition and age were understood for the first time.
