Structural Analysis of the Cave Sites in Japan

(1)分布研究1967年，日本考古协会对日本境内的洞穴遗址进行了调查，共发现了173个洞穴遗址。1996年，在我们项目的调查中，它们的数量增加了508只，达到681只。通过收集它们的平面和剖面，我们确定了它们的尺度和生活区。(2)挖掘研究我们进行了以下四项挖掘工作；大山洞穴遗址（古坟时期独木舟型墓葬）千叶县立山石窟（聚落，绳文时期）长崎县横手石窟（开放遗址，旧石器时代）长崎县佐世石窟（营地遗址，绳文时期）岐阜县吉木郡上土村(3)专题讨论会每年我们都会召开专题讨论会，作为年度报告来完成我们的研究。这次讨论使我们在洞穴遗址的研究上取得了很大的进展。课题如下：“古坟时代的独木舟式墓葬”、“绳文初期洞穴的利用”、“洞穴的起源”、“洞穴作为人类居住的时代”等。

(1) DISTRIBUTION RESEARCHBy the research of the cave sites in Japan that the Japanese Archaeological Association made in 1967,173 cave sites were found. 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.
