HIGH LIGHT 03 Biodiversity Conservation Green Townscape Proposal Combining the Strengths of the Group

Our society is built upon various bounties of nature. Despite of this, biodiversity and the ecosystem has been impaired by the rapid development and modernization. As such, there are expectations for companies to engage in urbanization that consider biodiversity in line with the Aichi Targets set out in the 10th meeting of the Conference of the Parties to the Convention on Biological Diversity (COP10) in 2010.

The Sumitomo Forestry Group engages in business activities considering biodiversity based on the Group Environmental Policy and strives to conserve biodiversity of the region through property development and greening business.


Example: SDG targets 11.3

By 2030, enhance inclusive and sustainable urbanization and capacity for participatory, integrated and sustainable human settlement planning and management in all countries.

Sumitomo Forestry's contribution in achieving the goal

  • Promotion of eco cities through greening business
  • Utilization of Harmonic Plants®
  • Promotion of biodiversity initiatives

Acquired first ABINC certification for detached housing complex
Sustainable Property Development Considering Biodiversity Forest Garden Hadano

Forest Garden Hadano, a detached housing complex in Hadano City, Kanagawa, is an example of the result of the combined efforts of the Sumitomo Forestry Group companies to realize sustainable property development. It received the first ABINC*1 (Association for Business Innovation in harmony with Nature and Community) certification under the detached housing complex and city area category.

The complex made full use of spring pond which is a local symbol with a property development concept of "Water, Wind, Light, and Greenery." It is also designed with consideration to biodiversity. Specifically, Property Design Guideline is distributed and complied by all households to maintain its design to create one large green area by connecting the greenery of each housing. The guideline also includes detailed rules on garden vegetation to maintain set amount of greenery. Households can choose from our unique Harmonic Plants®*2 to plant and preserve the local tree species. Furthermore, lawn and gravel are used extensively to create more unpaved areas in consideration of circulation of water in the region. Each housing is installed with rainwater tanks and rain garden (water infiltration green zone) as part of the design to preserve rainwater from flowing out of the region (for sold housing lots ).

These consideration to environment, circulation of water and materials that contribute to biodiversity and management system for greenery received high praise.

In the design and construction, Residential Property Development Department, Sumitomo Forestry Landscaping Co., Ltd., and other departments and related group companies joined the housing and construction departments to share their knowledge and ideas. This truly was a property development plan actualized by the combined strength of the Group.

On the other hand, understanding and support of the residents are essential to realize and maintain the meticulous concept of the Forest Garden Hadano. Continued communication with the residents even after their purchase is indispensable. We plan to hold study sessions and monitor over 30 species living in the region as part of the three-year maintenance plan. These community activities is part of the sustainable property development considering biodiversity and will lead to further increase the asset value.

*1 ABINC: Certification system that recognizes the development of green zones, maintenance, and use that consider biodiversity by companies.

*2 To utilize plants considering biodiversity for effects on the ecosystem and genetic strains according to the location of gardens.

Promoting Sustainable Property Development for the Residents

Countless thoughts and wishes have been incorporated in the Forest Garden Hadano from its planning stage. One example is landowners’ wish to utilize spring pond, the symbol of the region. This lead to the concept of "Water, Wind, Light, and Greenery."

Being responsible for the exteriors of the property development, we relentlessly studied ways to connect the greenery of each housing to create one large greenery and ways to connect pavement and materials to express an unconstrained property that flows like wind and water and create a unified look of the property. We formulated the Property Design Guideline to create greenery and were able to create a living environment and landscape of property that was connected and with rich greenery.

After the completion of the sale, gentle wind and sounds of the stream, songs of birds, and voices of children all resonate every time I visit. With the continued support of the residents, we were able to acquire the first ABINC certificate as detached housing complex. I would like to continue engaging with passion in sustainable property development valuing communication.
