Hajime Kensetsu Co., Ltd. (Headquarters: Toshima-ku, Tokyo; President: Tadami Horiguchi; hereinafter 'Hajime Kensetsu'), a core company of the Iida Group Holdings, has renewed its special page 'Hajime no Gijutsu' and launched it on Wednesday, April 1, 2026.

Special Page URL: https://www.hajime-kensetsu.co.jp/commitment/06/

In this renewal, we have expanded the content and reviewed the structure with the aim of conveying the proprietary technologies developed by Hajime Kensetsu more clearly to customers considering purchasing a home.

We have organized and refined the presentation of technologies that support the safety and quality of housing, such as our proprietary load-bearing wall 'HW5.0Σ' and the 'HT Base' foundation construction method, making the site visually easier to understand.

Background of the Renewal In recent years, the performance required for housing, such as earthquake resistance, wind resistance, and thermal insulation, has become diversified and sophisticated, and customer interest is increasing. On the other hand, these technologies and performances are highly specialized, making it difficult to understand their differences and value.

Hajime Kensetsu has carried out this renewal of the special page with the aim of solving these issues and helping customers 'understand the safety and quality of their homes more correctly.' We aim to provide information that allows customers to proceed with their home selection with peace of mind by carefully conveying not only technical introductions but also the development background and features.

Main Renewal Points 1. Expansion of Information on Proprietary Technologies We have expanded information on Hajime Kensetsu's proprietary structural technologies. The structure is designed to deepen the understanding of housing performance by clearly introducing the role and features of each technology.

2. Easy-to-understand Visualization of Technology We have revamped the content to allow intuitive understanding of structures and mechanisms by utilizing construction photos and conceptual diagrams. Even those without specialized knowledge can easily imagine the strength and mechanisms of the housing.

3. Concrete Introduction of Design and Construction Ingenuity We clearly introduce the development background and ingenuity born from on-site challenges, such as 'HW5.0Σ,' the first minister-certified load-bearing wall with a wall ratio of 5.0 using wooden braces, and the 'HT Base' foundation construction method that achieves both construction efficiency and quality improvement.

Hajime Kensetsu will continue to promote technological development that balances the improvement of housing performance with cost optimization, and will work to create an environment where customers can choose their homes with peace of mind through easy-to-understand information dissemination.
