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

Contributions to Property Development

Project to cultivate leaders to form an ecological network for corporate green zones along the coastal area of the Chita Peninsula received a special jury prize at the Environmental Awards 2019

In the industrial zone along the northern coast of the Chita Peninsula in Aichi Prefecture, this conservation initiative brings together corporation green zones as regional ecological sites to unify students, companies, NPOs, and government agencies.

In June 2019, these Chita Peninsula ecological conservation efforts provided an excellent example of an initiative to conserve the ecosystem through a consortium honored with a special jury prize in the 46th Environmental Awards (held by the National Institute for Environmental Studies, Japan and Nikkan Kogyo Shimbun with the support of the Ministry of the Environment).

Sumitomo Forestry Landscaping joined this project as an advisor and consultant with MS&AD InterRisk Research & Consulting, Inc. and Regional Environmental Planning, Inc. We cooperated broadly by providing advice such as methods for greening renovations that increase biodiversity and methods to monitor life with the participation of students and employees.

As the recovery of biodiversity becomes of major interest today, Sumitomo Forestry will not only further deepen but also broaden its consulting capabilities related to biodiversity conservation.

Assisting Nakashinden Green Area of Aichi Steel Corporation and the Central Negishi Refinery Garden of the ENEOS Corporation to Receive ABINC Certification

The Nakashinden Green Area of Aichi Steel Corporation (Aichi Prefecture) that Sumitomo Forestry assisted in obtaining the ABINC certification* is a roughly 2 ha corporate green zone adjacent to the plant in the head office district of the company. The area had originally been used for a plant, but this plan set out to open the zone as a local ecological site. The project was able to take advantage of the marshy and grassy environment to create a natural ecological garden. Employees, local citizens, student volunteers, and many others are helping build this green area to nurture even greater biodiversity.

In the same way, the central garden at the ENEOS Corporation refinery (Kanagawa Prefecture) that Sumitomo Forestry assisted in obtaining the ABINC certification* is a large-scale green space 100 meters wide and 800 meters long with three biotope ponds. In recent years, the initiative has been aiming to create green areas friendly to biodiversity by linking to nearby lush natural areas, such as the Sankeien Garden. Undeveloped woodlands on plant premises are expanding diverse environments, such as the water lands attracting kingfishers and grasslands filled with common bluebottle butterflies.

As shown by these two examples, efforts to try and transition production plant gardens into green areas where biodiversity flourishes are booming. In the future, Sumitomo Forestry will emphasize consulting related to the biodiversity conservation even more.

* This system certifies results of biodiversity preservation activities of companies to promote coexistence of nature and people.

Exhibited a Garden at the 36th National Urban Greenery Fair in Shinshu

The “Gift from the North Alps” Shinshu Flower Festival 2019 at the 36th National Urban Greenery Fair in Shinshu (Hosted by: Nagano Prefecture, Matsumoto City, Omachi City, Shiojiri City, Azumino City, and the Organization for Landscape and Urban green Infrastructure; Proposed by: Ministry of Land, Infrastructure, Transport and Tourism) was held over 53 days from April 25 to June 16, 2019 using the Nagano Matsumoto Daira Park (Shinshu Sky Park) as the main venue.

The National Urban Greenery Fair is a festival of flowers and nature that has been held every year throughout each region in Japan since 1983 as a project to raise awareness of property development that pursuit of comfortable, welcoming living filled with greenery.

Under a theme of connecting nature to forests, people, and the future, this fair advocate various greenery from original wall gardens to highly-durable wood decks and wood fencing, locally produced stone materials for local consumption, and vegetation suitable for different environmental conditions. In addition to native species such as Japanese white birch, Japanese dogwood, siebold maple, azalea, and Lily-of-the-Valley indigenous to Nagano and popular garden plants, this festival showcased how to cultivate a pleasantly refreshing garden unique to Shinshu that was then put on display.

Education for Biodiversity Conservation

Publish of Biodiversity Handbook Vol. 2: Local Vegetation

We are receiving a wide range of concerns for information about what the local vegetation is to the production, distribution and consumption of native plants and the cultivation plans for native plants in addition to future trend of local vegetation required for greening that consider biodiversity.

Sumitomo Forestry Landscaping has responded to these concerns by publishing the Biodiversity Handbook Vol. 2: Local Vegetation in January 2018.

This handbook offers explanations while interweaving cutting-edge examples that use locally cultivated plants to address primarily the information below.

  1. Reconstruction projects for the Great East Japan Earthquake using local plants
  2. The development of large-scale test driving course using local plants in
  3. Beach plant revitalization project using local plants
  4. Urban redevelopment using local plants from the Edo period
  5. Mixed tree revitalization using local plants cultivate on large-scale artificial grounds

Publish of an Illustrated Guide to Home Trees Revised Edition

The Ministry of the Environment and The Ministry of Agriculture, Forestry and Fisheries of Japan newly released a list of alien species which harm biodiversity of Japan (list of potentially harmful alien species for biodiversity) for the purpose of deepening interest and understanding about alien species to incite the appropriate action by various independent entities.

This list not only stipulates the specified alien species up until now but also selects alien species which have the potential to become highly invasive to the ecosystem or kill or harm people as well as damage agriculture, forestry and fisheries.

Sumitomo Forestry Landscaping has reorganized criteria for alien species unique to its business in accordance with the regulations on the list of harmful alien species for biodiversity with considerations to further impact on the ecosystem. The Illustrated Guide to Home Trees published based upon this criteria has released a revised edition in March 2017 which replaces some of the tree species included therein.

We will continue to advocate Harmonic Plants® and the use of these standards for alien species to include in proposals for plants to customers as well as in raising the awareness of our employees.

Overseas Greening Businesses

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 January 2017, Sumitomo Forestry 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. Even in the second stage of park planning conducted thereafter, we proposed basic concepts to further tasks to bring together the basic design founded upon this idea and moved forward with the construction set to be complete in September 2020.

Green zones in Australia and the U.S. is imperative to raise the value of the estate development and pursue the creation of efficiently green open spaces. Even in South East Asian regions where Sumitomo Forestry has been advancing housing and real estate businesses since 2019, initiatives to work in cooperation with local landscaping companies have started. We have just begun our efforts in the overseas greening business, but will continue to further these businesses in the future with the aim of creating beautiful and comfortable spaces loved by residents overseas.
