A Study on Spatial Change of Modern East Asia Using Cadasters and Cadastral Maps of Japanese former Colonies

本研究的目的是确定二战前日本前殖民地的地籍和地籍地图的位置和状况，并厘清日本移民在土地利用、土地所有权、城乡发展和各种活动等方面的详细过程。研究结果如下：首先，通过对日本包括冲绳、台湾和韩国的考察，发现日本大陆、冲绳和北海道、台湾和韩国的地籍和地籍地图的绘制顺序大致为：日本大陆、冲绳和北海道、台湾和韩国。由于地籍和地籍地图是在明治时代测量的基础上获得的，地籍地图的精度有所提高，特别是韩国地籍地图的精确度有所提高。这些地籍和地籍地图通常由地方政府保存，但部分材料被战火损坏或摧毁。其次，在空间变化方面，涉谷和鸟取根据地籍地图(特别是其原始地图)对景观进行了详细的重建。山本、内藤和川原通过使用出现在地籍和地籍地图上的名字来展示当时人们的活动。这些研究结果表明，地籍和地籍地图将成为现代东亚研究的重要工具。

The purpose of the research is to confirm the location and the condition of cadasters and cadastral maps made in former colonies of Japan before World War II., and to clarify detailed processes such as land use, land ownership, urban and rural development and various activities of Japanese immigrants.Results of the research are as follows.First, through the examination in Japan, including Okinawa, Taiwan, and Korea, it turned out that cadasters and cadastral maps generally were made according to the following orders: mainland Japan, Okinawa and Hokkaido, Taiwan, and Korea. As cadasters and cadastral maps got based on survey at the Meiji Era, accuracy of cadastral maps improved; especially Korean cadastral maps are accurate. These cadasters and cadastral maps are usually kept by local government; however some parts of materials are damaged or destroyed by the fires of war.Second, as to the spatial change, Shibuya and Todoroki reconstructed landscape in details based on cadastral maps (especially its original maps). Yamamoto, Naito, and Kawahara showed people's activities at that time, by using names appearing on cadasters and cadastral maps. These results of our research suggest that cadasters and cadastral maps would become an important tool in modern East Asian research.
