This paper deals with the formation process of a rectangle block in Kyoto of Edo period.
This consideration about the center gutter and neighboring boundary was premised on that the form of boundary line is equipped with objects corresponding to it. Generally, there were not any buildings in the inner part of the block, before neighboring boundary construction. Therefore, the land division was demarcated after neighboring boundary construction, in a rectangle block. However, partially, there were buildings in the inner part of the block, before bordering construction.
That is, it was generally formed in order of the buildings, the neighboring boundary, and the land division.
