Chief Director’s Message

Since it’s establishment in 1955, Public Corporation for Housing Improvement and Development has been working on housing and dwelling environment improvement according to the economic and social conditions.

The theme of housing has changed from “quantity “to “quality”, and the content of “quality”has changed from the number of rooms / size to efficiency and environment, but recently “use” has been focused on.

Originally, housing was just “used” for some purpose. And considering that, it may be natural that it is important to “use” housing as a space to utilize in their own way of living and working etc.

There is a great possibility that the tendency to choose a house from this point of view will accelerate further.

While accurately grasping the trends, we will utilize the specialized knowledge on rental housing management that we have accumulated so far, to develop our business and contribute to the stability and improvement of life.
