日本帝国内の建築に関する物・人・情報の流れ

二〇世紀アジア広域史の可能性

抄録

This article considers some relationship between the home country and some colonies of the Empire of Japan with the viewpoint of the flow of Portland cement, Japanese architects and architectural information within the territory ruled by Japan in the first half of the twentieth century. I have mainly two reasons why I focus on the flow of them. The first one is that all of buildings by Japanese on any cities ruled or occupied by the Empire of Japan had been necessary for colonization. The second one is that I have already recognized a lot of Japanese architects to move into Japanese colonies and to work in the first half of twentieth century.
On chapter 1 I try to analyze two matters, the one is to research some history of Portland cement factories in Japan and the Japanese colonies. In the Japanese colonies the first Portland cement factory is the Dairen branch factory of Onoda Portland Cement Co. Ltd., established in 1909 in Dalny, in the Kwantung Leased Territory, in the Manchuria. Not only it had supplied any Portland cement to the Kwantung Government General and the South Manchuria Railway Company, but also it had shipped to the Japanese colony Chosen until 1916 and exported to China. The other is to make analysis some statistics of output of Portland cement, to make it clear that a lot of Portland cement made in Japan and the Japanese colonies had been exported to China, Hong Kong, Java, Philippine, Malaya, Indo-China, Thailand and India, etc.
On chapter 2 I research each transfer of some Japanese colonial architects who were the first chief architect of each architectural office on colonial government or the South Manchuria Railway Company Limited. All of them had experienced building activity on the Japanese colony before becoming a chief architect of architectural office. Then transfers of them were not via Japan, but they moved directly one colony to another.
On chapter 3, I try to analyze some architectural magazines published in the Japanese colonies from 1920's to 1930's. I find out that all of them had carried any information on new buildings not on each Japanese colony, but on other territory in the East Asia or whole of the world. By reading them, Japanese architects on the Japanese colonial territory had gained latest design and theory of architecture in the world, and they had put the information to their building activity.
In conclusion, the territory ruled by the Empire of Japan was the place where Japanese architects had experience to get some new information and to product new works.
