Abstract
This study discusses on problems of quantity and types of public housing, which is expected to occur with increase of aged inhabitants and one-person households. Firstly, the necessary number of units of public housing in Kanazawa is estimated. Secondly, based on the results of the estimation, we run a simulation to explain how long and how many units we need when the percentage of the units for one-person households is raised to 80% in Kanazawa municipal housing. As a result, the necessary number of units increases until 2025 and subsequent policy development needs to reconsideration later. On the other hand, it takes about 45 years until the number of units for single person accounts for 80% by rebuilding. Moreover, municipality should address quickly the problem of an increase of old buildings.
