SocialDiversity & Inclusion
Work-Life BalanceReal estate development is intrinsically interlinked with local
ecosystems and natural environments. We must grasp and reflect
upon how we impact our surroundings, both directly and indirectly.
Tokyo Tatemono Group is working toward a vision ofcreating a pleasant city and living with greenery, a commitmentthat is included in our Group Environmental Policy. We arestriving to create a rich and comfortable environment thattakes biodiversity into consideration, by maximizing the powerof greenery, surveying local vegetation and the distribution oforganisms, and selecting tree species to plant. Our efforts
have been evaluated by impartial third parties, including
ABINC, a third-party certification system for biodiversity
conservation, and SEGES, a third-party certification system forgreen space creation.

New Initiatives to Restore Urban Biodiversity
The Otemachi Forest in Otemachi Tower (Chiyoda-ku, Tokyo) isa genuine forest that covers about one-third of the entire site(about 3,600m2). To develop it, we secured an experimental
pre-forest facility of woodland covering 1,300m2 in Kimitsu City,Chiba Prefecture. Over a three-year period, construction
methods, plant growth, and appropriate management methods
were verified in the same kind of growth environment as theplanned site. After the soil and plants had been cultivated inKimitsu, they were transplanted to the building site.
About 100 species of trees and ground cover plants wereinitially planted. A biodiversity monitoring survey conducted
about a year and a half later revealed that this number had
increased to some 300 species of plants. Many of thesespecies are thought to have grown from seeds contained in thesoil. Among them are rare species included on the national andmetropolitan governments Red List.
While the surrounding area is an office district densely
packed with tall buildings, the nearby Imperial Palace is home
to a large number of birds and insects. This serves to increase
diversity every year and contribute to the local ecosystemthrough a network with the surrounding green spaces. Several
bird species have already taken root and migratory birds havebeen confirmed. Insects include many dragonflies, whichappear to have flown in fromthe Imperial Palace.
The Otemachi Tower hasreceived ABINC certification
for biodiversity conservationand SEGES (Social andEnvironmental Green Evaluation
Otemachi ForestSystem) certification as anurban oasis.

Maintaining and Preserving Ecosystems through theCreation of Urban Greenery
To provide greenery at scale in urban areas where it is scarcerequires a stance not of preserving green space, but of creating it.
Tokyo Square Garden (Chuo-ku, Tokyo) is a newenvironmentally friendly building complex that features a
3,000m2 multi-story green space called Kyobashi-no-oka,along with solar power generation and high-efficiency heatsource equipment. The Tokyo Square Garden has received
ABINC certification for biodiversity conservation and SEGES(Social and Environmental Green Evaluation System)
certification as an urban oasis.
This initiative is not limited to our Commercial Properties
Business; we are also actively working on advancing it in ourResidential Business. Based on the concept of creating a forest
in front of the station, Brillia Towers Meguro (Shinagawa Ward,Tokyo) features a forested space on the property, withapproximately 900 trees planted and a dredged waterway. In
cooperation with the nearby Nature Study of the National
Museum of Nature and Science, we aim to contribute to thepreservation and growth of the local ecosystem.

Status of Implementation of Risk Assessment forBiodiversity
When developing real estate, we conduct environmental
assessment evaluations of flora, fauna, and ecosystems inaccordance with laws and ordinances related to environmental
impact assessments and nature conservation. Based on theseevaluations, we preserve, transplant, and conserve trees andforests as necessary.
