A Green Energy Supply Service developed by Mitsui Fudosan for tenants engaged in decarbonization was introduced at the same time to provide green power in a manner that flexibly accommodates tenant needs.
Moreover, in parallel with this, the Company is currently applying for “Top-Level” Facilities certification for outstanding global warming countermeasure efforts under the Tokyo Cap-and-Trade Program, which looks at management and operations related to energy efficiency and carbon dioxide reduction since a property’s completion and opening. When acquired, it will be Mitsui Fudosan’s tenth property to earn the certification.
The Company intends to continue providing spaces, environments and services to meet diversifying work styles and promote environmentally friendly urban development that is safe, secure and pleasant in order to achieve a sustainable society.

（2）) Environmental considerations and safety/security initiatives that help raise BCP performance
a. Energy and resource measures (initiatives for realizing a decarbonized society)
i. Adoption of technologies for reducing environmental impact
- Efficient energy use through installation of gas co-generation facilities
- Building of district heating and cooling (DHC) sub-plant
- Thermal load reduction via high-performance glass (low-e glass, etc.)
ii. Introduction of green power
- Mitsui Fudosan, through its partnership with TEPCO Energy Partner, began providing green power (electricity with non-fossil fuel certificates with renewable energy tracking) from April 1, 2021 at Tokyo Midtown Hibiya ahead of other properties. Along with green power for common areas within buildings, the Company also developed a green power supply service for tenant-only areas to flexibly provide green power in line with tenant needs, actively supporting the efforts of companies to realize a decarbonized society.
As of April 1, green power is now being provided to EY Japan, a tenant of the property. Tokyo Midtown Hibiya is Mitsui Fudosan’s first building to provide green power for both common areas and tenant areas.
b. Safety and resilience measures
- Control equipment boasting the world’s highest level of vibration control efficiency is used to ensure earthquake safety, and electricity can be supplied during disasters via dual-fuel emergency generators, which can run on either fuel oil or city gas. As countermeasures for water damage, key facilities are located on aboveground floors, and for belowground machinery, safety has been enhanced by, for instance, installing watertight doors.
- In building maintenance and management, appropriate management and operations are performed based on an established medium-term plan. A business continuity planning manual for emergencies has also been created and drills are conducted multiple times a year, including drills involving the entire building, in preparation of a possible large-scale disaster.
(3) Diversity and area environment considerations
- Tokyo Midtown Hibiya is used by a diverse group of people and it provides multilingual services not only in normal times but when circumstances make it difficult for people to return home. There are also universal access restrooms with entrances on both the men’s and women’s sides on standard office floors.
- Staff members keep barrier-free maps to Tokyo Midtown Hibiya with them at all times in both Japanese and English. The maps indicate steps and other potential barriers from nearby subway stations and other points in order to initiate smooth access to the property for visitors.
- Regarding considerations for the area environment, the building’s imposing nature was lessened through the design of the façade and exterior features, which give off a soft impression, vegetation was planted to blend the building in with Hibiya Park, and a large-scale green wall was established in Park View Garden on 6F, which is open to everyone.

(4) Collaboration with stakeholders
a. High level of management and operations from a united Mitsui Fudosan Group

Based on this track record, Mitsui Fudosan will apply this fiscal year for “Top-Level” Facilities certification for outstanding global warming countermeasure efforts under the Tokyo Cap-and-Trade Program.
b. Harmony with local communities
- Honoring relationships and connections with the local area, community events are held multiple times each year together with local community members.
