Abstract
Elderly housing and living conditions are as follows: elderly (+65 years) house owners'ratio is very high, 83.9%, but their houses are almost old and not barrier-free, elderly house owners remain their old house and don't move. The main reason which Japanese elderly households don't move is that the housing market underestimates their property. We need to build up the new housing systems for elderly, for example the continuous living system in their existing houses, the relocation system which they move to safe and comfortable houses or apartments, and the social support system for the poor and the weak.
