Characteristic and seaborne traffic in primitive and ancient Awa

阿瓦的考古和古代史特征推测，阿瓦是“大和”政府多年来海上交通的重要阵地和“东隅”统治的军事基地，因为《古古-水义》《高桥-世文》中讲述的家族传统故事或在立社法典制度下的阿瓦已被改编为“信郡”。然而，由于史料的限制和考古资料的匮乏，对古阿瓦压的真实性质的研究还很难说已经取得了足够的进展。之后，作为考古现场，在胜浦市守屋海岸开始了海洋侵蚀洞穴群的挖掘工作，并决定对该物质进行研究。”在平成10会计年度对海蚀洞进行了分布调查，并对本竹寺洞和森屋洞进行了调查。以此为基础，在11、12会计年度对本州寺洞和土部洞进行了挖掘，在13会计年度对Koumori-ana洞进行了挖掘。从绳纹时期到古坟时期，“开民”生活在该地区的生活和习俗得以澄清。特别要指出的是，解决了弥生时代到古坟时代的占卜用骨仪式的实际情况。古代史调查通过对阿坝相关史料、木碑资料、《印别史》的分析和对伊豆半岛相关地的考察，可以探究“开民”的历史形成过程和该地区的特色。

The special feature on the archaeology and ancient history in Awa is presumed that they were an important position of the seaborne traffic and a military base of "Tougoku" rule of the "Yamato" government for many years, because the family tradition tale in "Kogo-Syui" "Takahashi-shi-mon" told or Awa under the system of the ritsuryo legal codes having been made into "Shin-gun". However, because of restrictions of historical records and few archaeological data, it is hard to say that the research for the true nature of ancient Awa is pressed has advanced enough.Then, we started excavation of a sea erocion cave group at the Moriya seashore, Katsuura city as the archaeological field and decided that the substance is studied. Distributive investigation of sea erocion caves and survey of the Honjuji cave and the Moriya cave were conducted in the Heisei 10 fiscal year. Based on it, we conducted excavation of the Honju-ji cave and the Tyoube cave in the 11 and 12 fiscal year, and of the Koumori-ana cave in the 13 fiscal year.Life and customs of "Kai-min" in which it lived in this area from the Jomon period to the Kofun period were able to be clarified as a result of investigation. It should mention specially that the point of having solved the actual condition of a ritual of the bones used for divination from the Yayoi period to the Kofun period.Moreover, ancient history-investigation was able to explore the historical formation process as "Kai-min" and the special feature of this area which reaches through in analysis of Awa-related historical records, wooden tablet data, and "Inbe-shi" and investigation of the Izu peninsula as a related place.
