Akasaka Intercity AIR Achieves Prestigious TSUNAG Certification

Akasaka Intercity AIR, a flagship building under the management of Nippon Steel Kowa Real Estate and Akasaka Intercity Management, has achieved the highest rating of "★★★ (Triple Star)" in the TSUNAG certification program. This certification, granted during a ceremony on April 25, 2025, by the Ministry of Land, Infrastructure, Transport and Tourism, marks a significant milestone for the facility as it is the first to receive this distinction.

The TSUNAG certification program evaluates the quality and quantity of green spaces maintained by private entities, focusing on climate change countermeasures, biodiversity preservation, and enhancing well-being. Akasaka Intercity AIR's commitment to sustainable practices has been recognized in these areas, reflecting a comprehensive approach to fostering environmental stewardship.

Building a Bridge Between Environment and People

Akasaka Intercity AIR emphasizes a harmonious coexistence with nature, implementing several initiatives to achieve this goal:

• - Climate Change Measures: Energy-efficient designs, the introduction of renewable energy sources, and greening strategies to combat urban heat islands.
• - Biodiversity Preservation: Conservation of native species in onsite green areas and utilizing pruning residues effectively.
• - Well-being Enhancement: Organizing participatory events in green spaces to support the mental and physical health of workers and local residents.

Engaging Community Events Focused on Well-Being

The facility's well-being initiatives have gained attention for fostering connections within the community. Here are some notable examples:

• - Distribution of Pruned Branches: Each month, branches from pruning activities are distributed to community residents and office workers, encouraging reuse in their homes.
• - Garden Tours: Regularly scheduled tours invite participants to learn about the concept of the green spaces, types of plants, and their maintenance, creating opportunities for engagement with nature.
• - Greenway Festivals: Utilization of greenways for community exchange events, featuring food stalls and a festive atmosphere, enhancing the interaction between people and nature.
• - Tug of War on the Greenway: An intergenerational activity that invites local residents and office workers to participate, fostering a sense of community.
• - Lunchtime on the Greenway: Encouraging people to enjoy their packed lunches outdoors amidst new foliage, enhancing relaxation and social interaction. Note: the lunchtime event started after the TSUNAG certification.
