Biodiversity Conservation

Contributions to Eco Cities Through Greening

Basic Policy

The use of as many plants as possible which are native to the region in property development is a growing trend as society shifts toward a goal to co-exist with nature.

In the midst of these trends, Sumitomo Forestry Landscaping has defined Harmonic Plants® guidelines for selecting plants species based on greening areas with the concept that using indigenous and local species in greening plans is in the best interest of natural revitalization. The Company has been promoting this model up until now.

There are plants that have grown in Japan since long ago (native plants) and plants that have come to Japan from abroad (migration plants) for trees. Among these migration plants, there are species that will overrun areas where native plants live due to their characteristics, which endanger the biodiversity of the region (invasive plants*).

Garden vegetation plans are separated into four areas that take into account the conservation level (protected areas, conservation areas, satoyama areas, urban areas) to select plant species based on these areas. For example, in urban areas when building gardens for residences, the colorfulness is represented by selecting a balance of greening plants from non-invasive migration plants around a main selection of native plants, including garden variety plants. In addition, the Group has in place a policy of not using invasive plants that clearly have an adverse impact on local ecosystems and a division responsible for coordinating technology at Sumitomo Forestry Landscaping Co., Ltd. checks that such species are not used.

* Specified alien species and alien species requiring caution as stipulated by the Invasive Alien Species Act

Forest Garden Hadano Receives the First ABINC Certification As a Detached Housing Complex

Sumitomo Forestry strives in the residential property development business by providing roughly 350 high-quality single-family spec homes each year through technical expertise accumulated in new custom-built housing and landscaping businesses. We develop long-lasting properties by taking advantage of nature with the goal of realizing a sustainable and prosperous society.

Forest Garden Hadano, a detached housing complex in Hadano City, Kanagawa Prefecture, received the first ABINC (Association for Business Innovation in harmony with Nature and Community) certification under the detached housing complex and city area category in 2018. The ABINC certification system certifies results of biodiversity preservation activities of companies to promote coexistence of nature and people. The certification began the certification of office buildings and commercial facilities from 2014 and has expanded its scope to include housing complexes and factories. Furthermore, detached housing complex and city area category and logistic facilities have been newly added.

The property design of Forest Garden Hadano is green property that coexists with life. It realizes rich greenery through the use of local tree species and Harmonic Plants®. Consideration toward sustainable circulation of water utilizing spring water was one of the major factors of receiving the certification.

A High-Rise Japanese Garden That Conveys the Beauty of Nature and Harmony

Hotel Yaenomidori Tokyo opened in the Yaesu Hatchobori area of Tokyo in 2020. The hotel's concept is to present the multiple aspects of Japan's beauty. On the very top floor is a Japanese garden for guests to experience a spiritual, Japanese-style, sophisticated calm despite being in the middle of the Tokyo business district. By using Shishiodoshi (water-filled bamboo tubes that clack against stones when emptied to frighten the wild) away, water basins and other waterscape devices, by planting trees that respond to the change in seasons, Sumitomo Forestry Landscaping carefully designed and constructed a space that conveyed the beauty of nature and Japanese culture through the five senses.

It harnessed its experience and technology to secure trees both below and above ground, to consider load limits of high-rise buildings, and to commit to planting native species.

UR Urban Renaissance Agency Tokiwadaira Danchi with SEGES First Accreditation for 'Sodateru-Green'

The SEGES (Social and Environmental Green Evaluation System) (Sponsored by: Organization for Landscape and Urban Green Infastruction) has certified the green space in the UR Tokiwadaira Urban Renaissance Agency's Tokiwadaira Danchi as an Excellent Stage 2 green space in the category of "Sodateru-green", which evaluates green spaces that contribute to society and the environment. This is the first green certification for residential areas.

In August 2020, the independent administrative Urban Renaissance Agency and Sumitomo Forestry signed a "Research Agreement on Effective Utilization of Residential Outdoor Space with Environmental Certification System", and have been conducting research on effective outdoor space utilization in apartment complexes. Tokiwadaira Danchi's green space was certified as Excellent Stage 2 in the SEGES "Sodateru-green" category in April 2021.

UR and Sumitomo Forestry are studying methods to utilize the rich green space that has been fostered over the years and has become a natural asset for the community, using the SEGES evaluation.

We aim to accomplish a town development in harmony with nature, where diverse generations can continue to live actively and safely, by utilizing the results of the research and supporting local activities and communication among residents of the complex.

Minister of Land, Infrastructure, Transport and Tourism Award at the National Urban Greenery Fair Hokkaido

In the garden exhibition contest held within the 39th National Urban Greenery Fair Hokkaido in 2022, a work exhibited by Sumitomo Forestry and designed and supervised by Sumitomo Forestry Landscaping, the "Glamping Garden for Living with the Comfort of the Forest", received the highest award, Minister of Land, Infrastructure, Transport and Tourism Award and the Gold Award.

The award-winning entry was recognized for its ability to design the spaces and its high level of technical skill in utilizing wood and plants. The work also takes the local community and the environment into consideration through local production for local consumption and decarbonization, such as the use of Abies sachalinensis from Hokkaido for the post and beam of the framework, as well as the transportation of major trees by rail. In particular, rail transport of trees has reduced CO2 emissions by about 80 % compared to transport by truck. Modal shift, which is a shift to a transport method with a smaller environmental impact, is expected not only to realize a decarbonized society, but also to address various social issues, such as the shortage of driver personnel.

Received the Minister of Land, Infrastructure, Transport and Tourism Award in the Housing Townscape Contest

Sumitomo Forestry Landscaping's Forest Garden Hadano and Queen Forest Nagareyama Ootakanomori won the Minister of Land, Infrastructure, Transport and Tourism Award and the Townscape Award, respectively, in the 16th Housing Townscape Contest in FY 2020.

The Foundation for Promotion of Housing Production's "Housing Townscape Contest" aims to promote districts and groups that have achieved a desirable townscape via the efforts of local inhabitants, especially residents, in maintaining and managing their homes. One project got the Minister of Land, Infrastructure, Transport and Tourism Award, and four projects obtained the Residential Townscape Award, two of which were awarded to Sumitomo Forestry Landscaping-constructed properties, out of the many entries received in the competition this year.

This is a result of Sumitomo Forestry Landscaping's contribution to attractive town planning that takes advantages of local characteristics. Sumitomo Forestry Landscaping will continue to expand its business to realize the goal of "Creation of a complete town."

* Sumitomo Forestry Landscaping did not receive the award directly, but applied through the local community association or the management association

Education for Biodiversity Conservation

Publish of an Illustrated Guide to Home Trees Revised Edition

A total of 46,000 copies of Sumitomo Forestry Landscaping's “An Illustrated Guide to Home Trees” have been printed since the first edition published in 2013, with two revisions afterwards.
The revised edition I was published in March 2017, following the establishment of the Invasive Alien Species List by the Ministry of the Environment and the Ministry of Agriculture, Forestry and Fisheries, and taking into account further impacts on the ecosystem. We also restructured Sumitomo Forestry Landscaping's own criteria for invasive species.
The revised edition II was published in March 2021 with partially altered content in response to the modification to the Plant Variety Protection and Seed Act and the addition of original varieties, and contains 508 species, including six original varieties.

(1) Revision of descriptions in response to the revision of the Plant Variety Protection and Seedling Law
The "Variety Registration Number" and other information were added to the original trees for sale and the trees registered as varieties in the illustrated book in compliance with the modification of the Seed and Seedling Law, as registered varieties are now obliged to be labeled.

(2) SDGs (Sustainable Development Goals) initiatives were added
Through its green business, Sumitomo Forestry Landscaping Co., Ltd. is implementing initiatives in line with the SDGs, such as protecting biodiversity through the concept of "Harmonic Plants" in the consideration of sustainability, and creating comfort, enjoyment, and beauty in society by constructing homes and communities that harness the "Power of Greenery". We are putting these initiatives into action. These initiatives have been included in this revision.

Recognition of Contributions to Environmental Consciousness

Sumitomo Forestry Landscaping has begun assessing carbon storage by trees in residential gardens as part of its efforts towards a decarbonized society. Trees play an important role towards a decarbonized society as they can absorb CO2 during their growth and continue to fix it as carbon.
Combined with Harmonic Plants®, a guiding principle of Sumitomo Forestry Landscaping, the aim is to create gardens that take into account local biodiversity, while also looking at the environment of the entire planet.
At Sumitomo Forestry's model house in Yonago, plantings were mainly of native species in accordance with the Harmonic Plants® guidelines. As a model case for LCCM housing, carbon storage in gardening was also assessed.
The amount of carbon storage was calculated for trees, wooden decks and wooden fences as materials that can be used for carbon fixation in gardening. The garden at the Yonago model house fixes approximately 6.2 tonnes of CO2 equivalent (equivalent to the carbon storage of about 21 trees of 40-year-old cedars in an planted forest).
In the future, the system will be developed to enable simpler assessment, and preparations will also be made to enable recognition of the fixed volume that increases as properly managed trees grow.

Overseas Landscaping Businesses

Expansion into the Landscape Business in Australia

In 2022, Sumitomo Forestry acquired Regal Innovations, a landscape business* in Australia, as a subsidiary. The company is also involved in leading development and construction projects in urban Sydney, and accelerates efforts to address environmental issues through the creation of landscapes in harmony with nature in the design and construction of commercial areas, public facility housing exteriors, green zones and parks. When creating spaces, not only are plants, wood, stone and soil used, but also rainwater circulation and techniques for restoring and preserving vegetation are incorporated. Technological exchange between Japan and Australia has also begun, including the sharing of garden vegetation and green space management know-how by Sumitomo Forestry Landscaping, and design proposals for landscape design. In the future, we will combine this with our housing, construction and real estate business to promote more environmentally sound development in Australia and other countries.

Design Collaboration in Australian Subdivisions

In North Melbourne, Australia, we are leveraging our expertise in a design partnership with Tract Landscape, a local landscape design firm, for the Annadale estate project (1,087 total lots for sale), which is a joint residential development project between Sumitomo Forestry and NTT Urban Development.

In this design partnership that began in 2017, Sumitomo Forestry Group proposed a concept, Growing Wellness Life & The Five Sense, for the basic design of Tract. Tract highly evaluated this proposal as a fantastic reference because a story is not usually incorporated into standard design plans in Australia and playground equipment using natural stone and logs was employed to better the motor skills of the children as well as the vegetation plans. The Sumitomo Forestry Group proposed basic concepts even in the second stage of park planning conducted thereafter and completed the basic design founded upon this idea in November 2020. In 2021, Sumitomo Forestry also collaborated on concept proposals and drafting work for a local government public park project in Sydney.

Green zones in Australia are imperative to raise the value of the estate development and pursue the creation of efficiently green open spaces. The Sumitomo Forestry Group has just begun our efforts in the overseas landscaping business, but will continue to further these businesses in the future with the aim of creating beautiful and comfortable spaces loved by residents overseas.
