TOYOTA ARENA TOKYO Achieves Japan's First "LEED® BD+C Gold" for an Arena Facility

Toyota Fudosan Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; President: Tomohide Yamamura) announced that "TOYOTA ARENA TOKYO," which it owns, has achieved "Gold" certification under LEED® BD+C: New Construction (LEED® for Building Design and Construction: New Construction) v4, an international green building standard. This marks the first instance of an arena facility in Japan obtaining LEED® BD+C certification*. Von Elph Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; Representative Director: Hiroki Hiramatsu) was responsible for supporting the certification acquisition for this project. *Among projects published in the LEED Project Directory ■ Toyota Fudosan Co., Ltd.'s Initiatives This arena, a next-generation sports arena, is scheduled to open in October 2025 in Aomi, Odaiba area, Tokyo. Under the concept of "Let's bet on possibilities," it aims to be a place that accumulates and unleashes diverse values such as sports, mobility, and sustainability. Among these, environmental consideration is one of the important pillars, pursuing sustainability in both design and operation. Optimize Energy Performance ・Introduced highly efficient equipment and district heating/cooling, reducing energy costs by 32.3% compared to the standard (ASHRAE 90.1-2010 Appendix G) based on building-wide energy simulations. Renewable Energy Production ・Installed 300kW solar power generation panels, the largest class for an arena facility in Japan, to substitute over 5% of the annual total energy consumption. Expected to generate approximately 310 MWh annually. Indoor Water Use Reduction ・Contributed to water conservation and water resource circulation by combining recycled regional water and rainwater utilization. Achieved a high reduction rate of 77.6% in indoor water use, combined with the adoption of water-saving sanitary fixtures. Open Space / Sustainable Sites ・Secured 44% of the site as open space, providing an area that promotes interaction among people. ・In rainwater management, controlled runoff outside the site and utilized rainwater or recycled water for irrigation of plantings. In addition, this arena has already obtained "ZEB Ready" certification*1, achieving a BEI value of 0.45*2, the highest rating for an arena in Japan. It has received top-class evaluations in major domestic and international environmental performance certifications. *1: Certification obtained based on evaluation under BELS (Building-Housing Energy-efficiency Labeling System), a domestic environmental labeling system. *2: Value obtained by reducing the facility's design primary energy consumption by 55%.
