The Japan 2X4 Home Builders Association has set up the “Association Format” for handling the “Housing Performance Indication System” that is part of the Housing Quality Assurance Act.

The Japan 2X4 Home Builders Association is designated a special group in the Organization for Housing Warranty system so that it can handle the obligations incurred under responsibility for ten year collateral. The Japan 2X4 Home Builders Association also provides a support system for member industries so that they can deal with the new age of competition in housing performance.
