Company Information


We would like to take this opportunity to extend our greetings and hopes for your good health and prosperity. In addition, we offer our warmest gratitude to you for your exceptional support and patronage to our business.
Since our establishment in 1977, we have expanded our business by continued our founding spirit of “contributing to society by providing the highest quality and more affordable homes” along with a strong management policy of “being a company that can foresee and always quickly adapt to any change in the times”.
In fact, we have been working earnestly to address the issue of improving the "quality" of housing in Japanese society that has moved toward stable growth, and developed our original I.D.S. construction method, pioneered the introduction of Housing Performance Indication System and Earthquake Resistance Testing. As a result, we were listed on the First Section of the Tokyo Stock Exchange in 2002.
In 2013 Iida Group Holdings Co., Ltd., the number one single-family home builder in Japan, was established and now we are its core operating company.
The achievement we have made so far is just a passing phase. Always looking ahead, we are accelerating our efforts in various new business fields, such as hotel, healthcare and overseas business, with single-family home business as our foundation. In the healthcare field, in particular, we are committed to creating new value for future homes and realizing future healthcare homes.
In the future, based on our long-standing achievements and accumulated know-how, we will continue to fulfill our social responsibility by pursuing "the highest quality and more affordable homes" and by "maintaining the company that can foresee and adapt to any changes of times quickly”, while keeping an eye on the state of affairs and making a turnabout".
Finally, we determine to continue our efforts to enhance our corporate value, and we appreciate to your continued support and patronage.
