Abstract
The aim of this research is to make clear the acceptance condition and evaluation of housing developers for Housing Performance Indication System (Apartment houses) in Housing Quality Assurance Act. The research was made for 21 major developers in Japan, and it was found that many developers positively have started to use the system and more will use it in the near future. But their main intention is to not kindly give information to the users, but to get users' reliance on the company itself now.
