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.

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.

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.

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.

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.
