ou2 Co., Ltd. (O2 Corporation: Koto-ku, Tokyo), which promotes homebuilding under the concept of 'No 10cm WastedⓇ' and operates businesses such as Cleverly Home Shoto and Shinjuku Stores, and OU2HAUS, has been awarded the 'Outstanding Contribution Award' by the Japan Wood Housing Industry Association (a general incorporated association) in May 2026. This recognition honors the company's significant contributions to improving the quality and promoting the development of wooden-frame construction homes. Moving forward, ou2 will continue to advance fire-resistant multi-story wooden housing technologies in urban areas and enhance its unique on-site management system—already recognized with hall of fame status in national competitions—to further contribute to the growth and popularization of Japan's wooden housing industry.

Background of the Award: Contributions to Quality Improvement and Development of Wooden Housing

This award is presented to companies and individuals who have made notable achievements in the healthy development of the wooden housing industry and the improvement of residential living standards. The core reasons for ou2's industry recognition lie in its concrete initiatives and their ripple effects as detailed below.

Promotion of Fire-Resistant Multi-Story Wooden Housing (MokuyonⓇ) on Urban Infill Sites

In central urban areas, where housing affordability is declining due to rising prices, the promotion of wooden homes—especially in fire-resistant zones—is an urgent priority for the housing industry from a carbon neutrality perspective. ou2 develops multi-story homes, including fire-resistant 4-story wooden houses, on extremely small and irregularly shaped plots in central Tokyo, often limited to around 30 square meters. Through advanced structural calculations and proprietary construction techniques, ou2 continues to offer 'wooden construction' as a viable option in urban areas where steel or reinforced concrete (RC) structures have traditionally dominated. This directly contributes to expanding market share and advancing the adoption of traditional wooden post-and-beam construction methods.

Enhancing Trust in Wooden Housing through Hall of Fame-Quality On-Site Management

Furthermore, ou2 has won the Grand Prix in the 'Model Site Contest,' a nationwide competition where builders and contractors vie for excellence in on-site quality and safety management, achieving hall of fame status. As issues such as craftsmanship succession, on-site safety and hygiene, and neighbor consideration remain industry-wide challenges in wooden construction, ou2's rigorous on-site management know-how serves as a model for improving overall industry standards. It ensures consistent construction quality and strengthens customer trust, setting a benchmark for the entire wooden housing sector.

For over a quarter of a century, ou2 has been engaged in the design and construction of wooden homes, primarily within Tokyo. The company was an early adopter in recognizing that Tokyo's many fire-resistant zones, combined with regulatory changes allowing 'fire-resistant buildings,' now permit wooden home construction even within these zones.

Generally, fire-resistant buildings in fire zones are still widely perceived as being limited to steel or RC construction, and the very existence of fire-resistant wooden buildings remains under-recognized. In this context, ou2 has actively promoted and supplied fire-resistant wooden homes.

Currently, approximately 30–40% of the wooden homes ou2 receives annually are classified as fire-resistant buildings. The company has focused on expanding awareness and orders for 'fire-resistant wooden housing,' and this award acknowledges those achievements.
