Since fiscal year 2024, the Obayashi Group has been holding ESG briefings to introduce its sustainability initiatives to institutional investors and securities analysts. On March 19, 2026, the Obayashi Group held an ESG briefing and site tour at a construction site in Yokohama, Kanagawa Prefecture, with 17 institutional investors and securities analysts in attendance.
This second ESG briefing was designed to allow participants to experience the Obayashi Group’s initiatives firsthand by touring a construction site—the front lines of our efforts to capture growth opportunity generated from social demand for “carbon neutrality and well-being” into business opportunities, as outlined in our Medium-Term Business Plan 2022.
During the briefing, Takayuki Tomioka, Managing Executive Officer, and representatives from the Carbon Neutral & Timber Construction Solution Department of the Marketing Division presented the Obayashi Group’s initiatives, such as domestic and international case studies of wooden structures and interiors, a roadmap for renewable energy adoption, and global human resource development. Additionally, during the tour of a construction site using domestically produced CLT (*1) and a visit to a wooden site office, we introduced construction management utilizing insights from full-scale mockups, the use of DX technologies such as 3D printers and Mixed Reality (MR) technology, safety initiatives, and efforts to foster employee well-being.
- The raw CLT (※1) panels used in construction are manufactured by Cypress Sunadaya, a company in which Obayashi Corporation has a capital alliance. Visitors observed areas where connections using LSBs (lug screw bolts) and connector hardware—also used at the Osaka-Kansai Expo—are managed with millimeter-level precision.
- Using the construction management application holonica, which utilizes MR technology, participants viewed a completed rendering of the construction project on a tablet.
- At the wooden site office, developed in collaboration with a leasing company for pre-fabricated offices, the construction site manager explained the positive effects created by the presence of wood and greenery, as well as various measures designed to create a comfortable workplace.
Participants asked questions regarding how the market environment and needs for wooden structures and interiors have changed in the approximately four years since the completion of Obayashi Corporation’s next-generation training facility “Port Plus®”—Japan’s first fully wooden fire-resistant high-rise structure building, which was introduced during the 2022 tour—as well as challenges in technological development for environmentally conscious architecture and the benefits of wooden structures and interiors. In response, we explained how we are contributing to market development driven by the government’s carbon neutrality initiatives through technological development that leverages the Obayashi Group’s strengths and proposals to our clients.
The Obayashi Group will continue to strive for the sustainable enhancement of corporate value by addressing various ESG challenges, including “carbon neutrality and well-being“, while responding to the needs of our clients and society and turning them into business opportunities.
We will also strive to engage in constructive dialogue with all stakeholders, including our shareholders and investors, and to enhance our disclosure practices.
