Public housing has been established to provide decent and safe rental housing for the eligible low income families and the elderly. Presently, there are approximately 2.18 million houses managed by municipalities in Japan, public housing reproduction projects have been stagnant. The reasons are as follows: there are numerous houses that require rebuilding or renewal, economy is in recession etc. In consideration of the situation, the plan to utilize the public housing stock has been introduced and has been adopted by municipalities. And when making this plan, municipalities must create the flowchart how to utilize each public housing conforming themselves to conditions. This research surveyed the opinions of municipalities, and analyzed each municipality’s flowchart. As a result, this paper will contribute to better reproduction projects of public housing.
