By precisely integrating the outer walls, roof and floor framing with structural plywood, the group has recently obtained the highest grade in Japan’s housing performance indication system for resistance to earthquake and wind. Likewise, the T Lock II system patented by one of IGHD’s subsidiaries can hold down pillars approximately twice as strong as regular fitting fixtures. In terms of comfort, another subsidiary has invented Air Lean II, which automatically controls air-flow rates through rooms, inside of walls and attics to check CO₂ concentration and expel tobacco smoke, solar-radiation heat and humidity.

Created by the merger of six leading Japanese real estate developers, IGHD can build a home in a very short time compared to competitors. At the same time, prices are very reasonable – monthly amortisations are lower than renting a house.

With such advantages, the group will be expanding overseas, beginning in China. To this end, one of IGHD’s subsidiaries has established a company on the mainland, and has conducted roadshow presentations in Hong Kong to attract potential investors. Moreover, the group has accepted many junior trainees from foreign countries such as China, Vietnam, Indonesia and Thailand. Many of them are expected to be the future bridgeheads for the group when they return home after the training.

“We supply about 40,000 houses yearly in Japan, so you can imagine how big we are in this business, with the No 2 company producing only about 3,000 units,” Nishikawa says. “With new partners and investors, we dream of becoming the world’s No 1 housing company.”
