Structural Analysis of the Cave Sites in Japan

(1)分布研究通过对日本考古协会1967年在日本进行的洞穴遗址调查，共发现173处洞穴遗址。1996年，在我们项目的调查中，他们的数量增加了508人，达到681人。通过收集它们的平面和剖面，确定了它们的规模和生命带。(2)发掘研究开展了以下四项发掘工作：小山洞穴遗址(独木舟式墓葬，高芬期)Tateyama-shi，千叶县Tateyama-shi，Sugino-o洞穴(片岩，柔门时期)佐世保石，长崎县横田遗址(开放遗址，旧石器时代)佐世保石，长崎筑石石窟(营地遗址，琼门时期)Kamitakara-Mura，Yoshiki-un，Gifu Pref。(3)SYMPOSIUMENY每年我们都会举行研讨会，作为年度报告完成我们的研究。这些讨论使我们对洞穴遗址的研究有了很大的进步，主要有：考芬时期的独木舟式墓葬、若蒙早期洞穴的利用、洞穴的起源、洞穴被用作人类居住的时间等。

And in 1996, their numbers increased by 508 to 681 in the survey under our project. With collecting their planes and sections, we confirmed their scales and their life zone.(2) EXCAVATION RESEARCHFour excavations we carried out are as follows ;Oderayama Cave Site (Canoe-type burial, Kofun period) Tateyama-shi, Chiba pref.Sugino-o Cave (Settelement, Jomon period) Sasebo-shi, Nagasaki pref.Yokote Site (Open site, Paleolithic period) Sasebo-shi, Nagasaki prefTsueishi Rock Shelter (Camp site, Jomon period) Kamitakara-mura, Yoshiki-gun, Gifu pref.(3) SYMPOSIUMEvery year we hold the symposium as an annual report to complete our researches.
