Preserving Biodiversity

Biodiversity-Related Approaches and Implementation Systems

The Mitsubishi Estate Group's Corporate Vision for 2050 involves the creation of an attractive society in harmony with nature through its business activities. All Group companies consider biodiversity in the course of their business activities and cooperate with NPOs and other organizations on biodiversity-friendly initiatives. The number of properties with ABINC certification is also an important CSR KPI and the company recommends properties with a certain amount of green space in one area for certifications.
The biodiversity initiatives carried out by the whole Group fall under the oversight of the company's CSR & Environmental Sustainability Department.

Improving the Waterfront Environment and Preserving the Ecosystem of the Imperial Palace Moat

The Mitsubishi Estate Group undertakes a lot of projects meant to protect biodiversity and improve the environment in the Marunouchi area. One example is the building of Hotoria Square, an environmentally symbiotic green space encompassing about 3,000 m² in front of the Imperial Palace moat. In May 2018, we started a Moat Project intended to improve the waterfront environment and revive the ecosystem in the moat. This began with collecting and observing the few water plants and animals living the water. The collected plants and animals were moved to Hotoria Square and a rooftop container biotope owned by Mitsubishi Estate where they will be monitored with the aim of preserving rare species and restoring the water environment.

Otemon Tower-JX Building Equipped with Water Purification Facility for Imperial Palace Moat

In recent years, the quality of the water in the Imperial Palace moat has deteriorated significantly as a result of a lack of fresh water. The Otemon Tower-JX Building, which was completed in November 2015, is the first private-sector project to introduce a rapid water purification facility capable of purifying up to 500,000 m³ of water a year to improve the water quality in the Imperial Palace moat. Additionally, to prevent water from stagnating as a result of low water levels in the moat, the facility is also equipped with a massive water reservoir with reserves equivalent to about six 25 m swimming pools to release water into the moat. Since the completion of the project, the rapid water purification facility has been slowly but surely helping improve the quality of the water in the moat.

Mitsubishi Jisho Residence Wins ABINC Award for Biodiversity Program

Mitsubishi Jisho Residence has expanded the BIO NET INITIATIVE, The Parkhouse's biodiversity preservation program for all condominiums, originally launched in February 2015, to over 130 condominiums under The Parkhouse brand nationwide as of February 2018. The company plans the trees and plants for each property in a manner that will help to preserve biodiversity, regardless of the property's size and land area. In addition, in 2015 Mitsubishi Estate renovated the inner courtyard of Setagaya House, a condominium it owns for employee housing, transforming it into a biodiversity-promoting environment. This “experimental garden” is also used for monitoring and communication programs involving residents.
In October 2016, Setagaya House won the Award for Excellence at the First ABINC Awards, given to ABINC-certified properties that make particularly impressive contributions to educating about the Association for Business Innovation in harmony with Nature and Community (ABINC) and bringing biodiversity into the mainstream. The Parkhouse Nishi Shinjuku Tower 60 also won a special award.

Biodiversity Preservation Initiatives at The Parkhouse BIO NET INITIATIVE Expanded to 100 Properties

Mitsubishi Jisho Residence has expanded the BIO NET INITIATIVE, a biodiversity preservation program originally launched in February 2015, to over 130 condominiums nationwide as of February 2018. Under this initiative, the company plans the trees and plants for all properties under its The Parkhouse brand in a manner that will help to preserve biodiversity, regardless of the property's size and land area. This creates a green space that serves as a stopover for plants and animals by linking the surrounding green space with the street's greenery with the aim of creating an ecological network in these areas.
Furthermore, The Parkhouse Wako and three other properties owned were awarded the Association for Business Innovation in harmony with Nature and Community's ABINC certification (condominium category) for 2017 in a follow up from their win in fiscal 2016. This is their fourth consecutive year of getting the award since the system began and makes Mitsubishi Jisho Residence the business with the largest number of certified properties at a total of 17.
Mitsubishi Jisho Residence will continue to promote this initiative of planning trees and plans to protect biodiversity in all The Parkhouse properties regardless of property size or area. For properties that make exceptional contributions in this endeavor, the company will aim to fulfill the various certification standards required to receive ABINC certification and thereby continue to work on environmentally-friendly urban development.

Expanding the Use of Japan-grown Timber and Using Certified Forest Products
- Using Some Domestic FSC-Certified Timber as Standard Construction Material -

Mitsubishi Estate Home proactively uses forest thinnings and small diameter trees for its 2x4 structural materials, aiming to expand the use of Japan-grown timber in wood-frame homes overall. The percentage of Japan-grown timber used in structural materials by the company now exceeds 50%, one of the highest percentages among builders of 2x4 homes in Japan.
The Mitsubishi Estate Group is also effectively utilizing and expanding its use of timber grown in Yamanashi Prefecture as part of the Project to Raise the Value of Japan-Grown Timber (Japanese only). The project works in affiliation with the "Experience Nature" Project (Japanese only), an activity that promotes interaction between urban and rural residents in Hokuto City in Yamanashi Prefecture. From April 2018, it began to use Domestic FSC-certified timber as standard material for plywood floors. By promoting the use of economically-sustainable responsible timber, the company is helping to build a recycle-oriented society in harmony with nature.
In addition to this, Mitsubishi Estate Housing Components promotes the use of Japan-grown timber in structural materials for single-family homes, and in August 2010 the company obtained FSC-CoC certification, an international standard for distinguishing sustainably-grown timber from other timber during the processing and distribution stages.

Biomonitoring in the Marunouchi District

The Marunouchi District is bordered by the Imperial Palace and moat, Hibiya Park and other beautiful natural spots, so it is a good location to observe various kinds of living things throughout the year. Mitsubishi Estate has been running a biomonitoring survey in the Marunouchi district since 2009. It compiled the results and published the Marunouchi Living Things Handbook in June 2013. The Handbook provides information about the abundance of nature in the district and also suggests ways in which individuals can help protect biodiversity in their own areas. By doing so, the Handbook aims to function as a PDCA tool for ecosystem management in the district.
This initiative received positive feedback and won the Japan Committee for UNDB Award in the Tokyo Region Biodiversity Contest held at the GTF Green Challenge Awards 2013 organized by the GTF Greater Tokyo Festival Executive Committee.
The company will press on with its efforts to preserve biodiversity in the future.
