The research of the Middle Age marine transportation and the circulation in the Kii Channel and tneighboring area

Kii海峡及其周边地区是濑户内海和太平洋之间的重要通道。在日本近现代时期，它是西转通道的中心。然而，中世纪海上运输的重要性却被人们所忽视。本课题以淡水省、泉省、岐省、阿瓦省、土佐省等沿海省份的历史记载为基础，重点考察了中世纪的海上运输和流通的实际情况。由于对中世纪海上运输的史料记载有限，本文也利用了这些省份的庄园历史记载。例如，Royasan和Iwashimizu-hachimangu等寺庙和神社的历史记录和庄园的材料都包含在该项目中。海上运输曾被用于军事行动，因此也包括了关于海上运输的历史记载。提取了一个成为各省海上运输基地的锚地，考察了海上运输与流通的观点。在连接濑户内海的通道中，有一条通过大土村的通道和一条通过鸣人海峡的通道。可以确定的是，后者的转运站的地点被忽视了。研究结果表明，浅水省西南地区在海上运输中发挥了重要作用。此外，土佐省、阿瓦省和岐义省也成为木材和森林资源的供应地区。在先前的研究中，连接土佐省和泉省的通道在乌宁时代之后被用于濑户内海。然而，该项目表明，该航道从早期开始就被用作日本国内航道的重要商业通道。

The Kii Cannel and neighboring area are a crucial passage between the Inland Sea of Seto and the Pacific. In pre-modern ages of Japan, it functioned as a center in the western turn passage. However the significance of the marine transportation in the Middle Age has overlooked. This project focused on the examination of the medieval marine transportation and the actual condition of the circulation based on historical records about Awaji Province, Izumi Province, Kii Province, Awa Province and Tosa Province which were seaside provinces. Due to the limited historical records on the medieval marine transportation, the historical records of the manor in those provinces are utilized, too. For example, the historical records and the materials on the manor in the temples and shrines such as Royasan and Iwashimizu-hachimangu are included in this project. Marine transportation had been used for military action, thus the historical records on the marine transportation is included as well. It extracted an anchor ground which became a marine transportation base of each province, and examined the view of the marine transportation and the circulation. There are a passage via Daimotu-ura and a passage via the Naruto Strait in the passage to connect the Inland Sea of Seto. It was possible to confirm that the transfer-station place of the latter which was overlooked. The research result shows that Awaji Province southwest area had played an important role in the sea transportation. Also, it clearly shows that Tosa Province, Awa Province, and Kii Province became the supplying district for lumber and forest resources. In the former research, the passage connected Tosa Province and Izumi Province was used in the Inland Sea of Seto after the Ounin period. However, this project shows that this passage was used as an important commercial aisle of Japan's-domestic channel form the earlier days.
