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

Kii Cannel及其邻近地区是内陆海Sto和太平洋之间的重要通道。在日本近代以前，它在西方转向通道中扮演着中心的角色。然而，海上运输在中世纪的重要性却被忽视了。该项目以滨海省份Awaji、Izumi、Kii、Awa和Tosa省的历史记载为基础，重点考察了中世纪的海上运输和流通的实际情况。由于有关中世纪海上运输的历史记录有限，这些省份的庄园历史记录也被利用。例如，Royasan和岩水八条线等寺庙和神社中的庄园的历史记录和材料都包括在这个项目中。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录。它提取了一个锚地，成为各省的海上交通基地，并考察了海上交通和流通的观点。在连接内海的Seto的通道中，有一条通过Daimotu-ura的通道和一条通过火影忍者海峡的通道。可以确认，后者的中转站是被忽视的。研究结果表明，阿瓦济省西南地区在海上运输中发挥了重要作用。此外，它清楚地表明，托萨省、阿瓦省和基伊省成为木材和森林资源的供应区。在以往的研究中，连接土佐省和出水省的通道是在乌宁时期之后的内海司藤内海使用的。然而，这一项目表明，这条通道从早期就被用作日本国内频道的重要商业通道。

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.
