Gakken Cocofun Co., Ltd. (Shinagawa, Tokyo / President and COO: Takeshi Mori), a group company of Gakken Holdings Co., Ltd. (Shinagawa, Tokyo / President and CEO: Hiroaki Miyahara / hereinafter referred to as 'the Company'), which operates the serviced housing for the elderly 'Cocofun Fujisawa SST', has been certified as a building with extremely excellent 'environmental and social considerations' under the DBJ Green Building Certification (Healthcare Version). The certification was awarded on December 17, 2025, as a landmark first project. Following this, a certificate awarding ceremony was held on March 11, 2026.

■About the DBJ Green Building Certification
The DBJ Green Building Certification (hereinafter referred to as 'GB Certification') is a system for evaluating real estate ('Green Building') that incorporates environmental and social considerations. Based on a comprehensive evaluation that includes not only the environmental performance of the property but also responses to various stakeholders, such as disaster prevention and community considerations, it evaluates and certifies real estate that meets social and economic demands, and supports these initiatives.
The 'Healthcare Version' of the GB Certification, launched on April 1, 2025, aims to visualize the evaluation of real estate sustainability, including comfortable services and promotion of well-being in paid nursing homes and serviced housing for the elderly, as well as environmental considerations. It also serves as a dialogue tool for a wide range of stakeholders, promoting further sustainability improvements and engagement in the industry.
■Background and Significance of Initiatives for This Project
The Gakken Group promotes sustainability management towards the realization of a sustainable society. With a focus on reducing environmental impact and improving well-being, the group has set a goal to reduce greenhouse gas (GHG) emissions by 50% by 2030 compared to fiscal year 2022, and is promoting the development of ZEB-spec senior housing and the use of renewable energy.
In line with this group policy, 'Cocofun Fujisawa SST' has received high evaluations for its building's environmental performance, user comfort, and connection with the community, leading to the acquisition of GB Certification.
■Evaluation Points
The GB Certification evaluates based on ESG perspectives, visualizing ESG initiatives through assessment across five categories: Energy & Resources, Well-being, Resilience, Community & Diversity, and Partnership.
For Cocofun Fujisawa SST, in addition to the building's environmental performance, its advanced initiatives in user comfort, and community and diversity were highly evaluated, resulting in the acquisition of '4 Stars', a certification rank equivalent to approximately the top 10% of the domestic real estate market, signifying extremely excellent environmental and social considerations.
Through this certification, further enhancement of the property's competitiveness and brand value is expected.
Key points are as follows:
● In the Energy & Resources category, the facility contributes to reducing greenhouse gas emissions through the daily use of a cogeneration system and power supply to the facility from an on-site solar power generation system. Furthermore, the adoption of LED lighting throughout the facility, water-saving fixtures, and water-saving toilets promotes energy and resource conservation.
● In the Well-being category, the company strives to improve services by conducting user satisfaction surveys targeting relatives and residents themselves. It also enhances resident convenience through free internet access in all rooms and the attraction of mobile vendors. Additionally, the installation of monitoring sensors in all rooms and a dedicated rest area for employees contribute to reducing employee burden and improving the work environment.
● In the Community & Diversity category, the facility fosters interaction between residents and users of the on-site nursery school and cram school by providing a communal hall. It also creates communication with local residents by hosting community events. Furthermore, rooftop greening, wall greening, and parking lot floor greening contribute to mitigating the heat island effect within the premises.
