The Flow through the Inland Sea to Kinai in Medieval Japan and Regional Structure from the Viewpoint of Historical Geography

本研究考察了中世纪日本中心地区的商品流向基乃（京都的首都及其周边地区），并指出了商品流向中显示的区域结构。他的重点是内海（濑户内），这是通往基奈最重要的贸易路线。他在这里使用的资料来源是1445年保留在北兵库港海关的税务记录。从记录中，我们可以看到船舶入境的日期，船舶注册的港口名称，货物的项目和数量，纳税金额，等等。在那里登记的船只总数约为1950艘。这一记录涵盖了内海沿岸的100多个港口，包括靠近京都的酒井港，以及位于兵库港以西约300公里处的下关港。他的主要调查对象是濑津、哈里马、阿瓦治三省的37个港口，阿瓦省的9个港口，比先、比楚、宾果三省的24个港口。他关注每一艘船，逐项检查在每个港口装载的货物，对这些港口进行分类并指出其特点。此外，他还根据装载货物的港口模式对货物进行分类。最后，他提出了从内海沿岸地区到基奈的商品流动所显示的区域结构。

The present investigator examines the commodity flows to Kinai (the capital city of Kyoto and its vicinities) as a central district in medieval Japan and points out the regional structure showed in the flows.His focus is on the Inland Sea (Setouchi), which functioned as the most important trade route to Kinai. The material source he uses here is the tax record retained at the custom house of the port of North Hyogo in 1445. From the record, we can see the date of the entry of ships, the names of the ports where the ships were registered, the items and the volume of cargoes, the amount of the tax paid, and so on. The total number of the ships registered there amounts to about 1950. This record covers more than 100 ports along the Inland Sea, including Sakai, just close to Kyoto, or Shimonoseki, located about 300 km far away west of Hyogo port. He picks up as main subjects 37 ports in the provinces of Settsu, Harima and Awaji, 9 ports in the provinces of Awa and 24 ports in the provinces of Bizen, Bitchuu and Bingo. Paying attention to every ship, he examines item by item the cargoes loaded at each port, classifies those ports and points out their characteristics.Further, he classifies the cargoes through the pattern of the ports where they were loaded. In conclusion, he presents the regional structure showed in the commodity flows from the regions along the Inland Sea to Kinai.
