江戸会所地の沽券地化に関する研究  [in Japanese] A STUDY ON THE PROCESS OF "KAISHOCHI" CHANGING TO THE HOUSING LOT  [in Japanese]

This study is to consider how "Kaishochi" (the open space in the block), which was planned in initial Edo town, transformed into the housing lot, emphasizing on Nihonbashi area. To understand the changing process of "Kaishochi" I based my analysis from three historical maps and historical records of "Machibure". The analysis of this paper consists of four contents; (1)the formation process of "newly developed alley" when "Kaishochi" became the housing lot (2)how to build "newly developed alley" from the view point of "Machibure" (3)several types of "newly developed alley" when "Kaishochi" is built on the housing lot (4)several types of "Kaishochi" when its incorporated into certain surrounding city later on. Due to peculiar land formation process of Edo called "Kaishochi", the urban space of Edo town changed by mutual adjustments between townspeople and the image of the mature society is evident.
