Initiatives: Donate stored emergency food supplies to food banks.
TEKKO BUILDING always maintains a 3-day supply of emergency food sufficient for 2,000 people in case of a disaster. We regularly donate part of this stockpiled food to food banks that provide food and other assistance to welfare facilities and people in need. Through this measure, TEKKO BUILDING supports the building of food safety nets, and endeavors to mitigate corporate food waste.

Initiatives: Equip buildings with "All Gender”, barrier-free toilets and infant care/nursing stations
With the aim of promoting the principle of gender equality, “All Gender”, barrier-free toilets clearly indicated by the rainbow mark,have been installed and located near the limousine bus waiting lounge on 1F of the South Building and near the TEKKO AVENUE restaurant zone on B1F.
In cooperation with the policies of the local Chiyoda Ward government, this "All Gender”, barrier-free toilet is open to everyone who visits the building for sightseeing or shopping and has been designated a "Chiyoda Safe Toilet". In addition, an infant care/nursing station equipped with an infant formula heater and a diaper-changing table is available near the limousine bus waiting lounge.

Initiatives: Create a safe, comfortable environment by establishing the Tenant Service Center and providing business support services.
The Tenant Service Center on 2F ensures round-the-clock safety and comfort for tenants backed by attentive services based on the experience and know-how accrued since the founding of TEKKO BUILDING. The limousine bus station on 1F of the South Building with its direct connection to both Haneda and Narita airports combined with its next-door access to the megahub Tokyo Station and 22 JR and subway lines makes the building a base that connects tenants with cities nationwide and worldwide.
Boasting liberating spaciousness, relaxation booths and shower rooms, "Tekko Executive Lounge & Conference Room" facility on 4F of the South Building enhances tenant convenience with rental conference rooms with capacity up to 300 people, while a fitness club on 5F of the same building provides refreshing workout space.
People with disabilities have been requested to actually experience internal building flow lines and express their views and safety concerns which have been subsequently reflected in improvements. For example, free-standing signage in aisles which may pose an obstruction has been replaced with signage suspended from the ceiling and mounted on walls. In addition, all floors are equipped with "All Gender" barrier-free toilets that accommodate the needs of people with disabilities and ostomates.
All these facilities, services, and attention to detail create an environment that is safe to use, and comfortable for all workers and visitors.

Initiatives: Adopt high-efficiency building systems and shift to electricity from 100% renewable energy sources.
From 2021, the TEKKO BUILDING complex has been powered by 100% renewable energy-derived electricity*. This is just one facet of our initiative to contribute to achievement of zero greenhouse gas emissions and a "carbon free" society by 2050.
Other measures aimed at improving the building environment while mitigating any adverse impact on the urban environment include optimized CO2 sensor-controlled external air ventilation mix, carbon monoxide monitored parking lot ventilation, heated/chilled water supply system, and supply of water heated by electric room exhaust heat, In addition, the building boasts a natural ventilation system which exploits height differentials and the building’s outer wall sleeve, high-efficiency LED lighting, automatic motion sensor-controlled lighting, and low-e window glass and sun-tracking smart blinds. for improved heat insulation.
*This excludes emergency power generation and tenant businesses (e.g., restaurant kitchens) that use natural gas or other fossil fuels on their premises for the pursuit of their business.

Initiative: "Hai Duong Garden" serviced apartment project in the Socialist Republic of Vietnam
Hai Duong, an eastern district in the capital city of Hanoi, is an area dotted with large industrial parks and the focus of ongoing overseas investment.
Since launching operations in 2013, "Hai Duong Garden" with its offering of short- and long-term accommodations and offices has provided a quality work and living environment for expats from Japan and other countries.
The TEKKO BUILDING GROUP subsidiary responsible for project development and its operation is the first Japanese company in Vietnam to engage in licensed restaurant investment, to conclude land use contracts, and to acquire permits and engage in construction. Hai Duong Garden local staff include the elderly and people with disabilities, and the business continues to recruit locally and create local employment opportunities.

Initiatives: Intermediate seismic isolation structure and other measures to support Business Continuity Planning (BCP).
TEKKO BUILDING incorporates the district’s first intermediate seismic isolation structure capable of withstanding a “Great Kanto Earthquake”-scale event. The building is also equipped with an emergency power generation system capable of supplying emergency power for up to 10 days. Emergency electrical power is generated by dual-fuel gas turbines fueled by heavy fuel oil or natural gas supplied by seismic-resistant medium-pressure pipelines. In addition, flood barrier plates are ready to protect life and property from flooding. Also support for tenant disaster-related BCP includes enough emergency food and water supplies for 2,000 people for 3 days, thermal foil heat insulation blankets for 2,000 people, first aid kits, and power generators. TEKKO BUILDING is also improving systems and support for people who are unable to return home and are stranded in the building due to disasters.

Initiatives: Reduce environmental load, reuse resources, and minimize waste in every step from construction to operation.
In the construction of TEKKO BUILDING, recycled steel frames, recycled crushed stone, and other recycled materials were proactively used. Waste materials generated during construction were also separated and processed, resulting in a recycling rate of higher than 90%. After opening, rainwater and wastewater from building equipment and facilities, restaurant kitchens, etc., are collected and processed in an underground water treatment facility, and then reused. In order to raise the waste recycling rate, all trash and waste is thoroughly separated for recycling. Twice annually, TEKKO BUILDING holds "Environmental Enhancement Month", during which all tenants contribute to reducing the environmental burden through energy saving, promotion of resource reuse by waste separation and other activities.

Initiatives: Pursue greening using natural flora and promote ecosystem conservation through biotope creation.
Along the walking path on the west side of TEKKO BUILDING, efforts to restore and conserve nature seek to create a greenscape that would be authentically natural and native to the site. Drawing on research of the flora in the Imperial Palace grounds and the Institute for Nature Study in Shirokanedai, the TEKKO BUILDING site is planted with shirakashi (bamboo leaf oak), tabunoki (Japanese bay tree) and other trees and vegetation native to the Musashino region. In Kure City, Hiroshima Prefecture, a collaboration with affiliated companies has resulted in the creation of a vast biotope on78,000m2 of land owned by our company. Here environmental research on the relationship between vegetation and the ecosystem, and other studies related to the impact of surrounding environs on the site are being conducted. In addition, the endangered black medaka Japanese rice fish, which are indigenous to this biotope, serve as the focus of company-supported"medaka exchange meetings" with elementary and junior high schools around the world, and put the spotlight on the importance of nature and preserving the environment for the future.

Initiatives: Contribute to the creation of a sustainable society through active participation in regional organizations and corporate groups.
Through participation in the OMY (Otemachi-Marunouchi-Yurakucho) District Area Management Association and its affiliated organizations, and in the Japan Climate Leaders Partnership (JCLP) – a coalition of Japanese companies who hold the firm belief that economic prosperity and sustainability go hand in hand, TEKKO BUILDING is proactively participating in urgent efforts to revitalize the region, improve the environment, and realize a carbon-free society.
