Biodiversity
Our Approach to Biodiversity
In accordance with the Group's environmental policy, we will strive to create urban environments that are in harmony with nature by taking biodiversity into consideration and working to conserve and green the natural environment. We will also actively participate in local volunteer activities to raise employee awareness of biodiversity conservation.
Efforts to Protect Urban Greenery
Efforts through Business
Promotion of Greening
In order to improve the landscape and reduce the environmental impact, we are working on greening existing real estate and development properties. Specifically, we are planting trees on the rooftops and walls of office buildings, grounds of condominiums and detached houses to create green spaces. We are also focusing on rooftop greening, with a total of 3,927 square meters of green space planted so far as of the end of November 2022. We are planning to introduce this system to commercial facilities and hotels under development.
Symbiosis with Plants
T's garden Nishiterao, a rental condominium that we revitalized, has a variety of plantings in the courtyard and other areas of the property, and QR codes are attached to tall trees to know tree species. Residents can interact with the plants in their daily lives and enjoy the seasonal changes.
Efforts around the Head Office
Green Space around the Head Office
Tamachi Tosei Building is a 30-year-old existing building that has been renovated and occupied by the Tosei Group as its headquarters building from 2021. Over 30% of the more than 1,300 m2 of open space is greened, with a diverse mix of tall trees, medium-sized trees, shrubs, and ground cover, allowing residents to enjoy the changes in the seasons. The canal that runs in front of the building is visited by wild birds, creating an environment where one can enjoy the richness of nature even in the heart of the city. The courtyards on the 5th and 13th floors of the head office building are designed to replicate a Japanese garden, with a pond in which carp are kept, and trees in the garden provide perches for wild birds so that one can hear them chirping.
On the rooftop of Toranomon Tosei Building, which was used as the head office building until March 2021, we operated a rooftop vegetable garden in order to mitigate the heat island effect, raise employee awareness of the environment, and revitalize group communication. We grew flowers and vegetables according to the season and held a "harvest festival" to raise the environmental awareness of employees through employee-participatory events.
Participation in the "Minato City Adopt-a-Program," a community cleanup activity
Since October 2022, we have been participating in the "Minato City Adopt-a-Program" and engaging in community cleanup activities. The "Minato City Adopt-a-Program" is an agreement between Minato City and organizations that live, work, or study in Minato City to collaborate in the maintenance and management of roads, parks, and other facilities. In principle, once a month, employees of our group pick up trash and remove weeds from the streets and parks around our head office. Through these activities, the Group will contribute to environmental preservation and beautification of the Minato City where the head office building is located.
Social Contribution Activities
Tree-planting Activities
For seven consecutive years from 2009 to 2015, we participated as volunteers in the "Umi-no-Mori (Sea Forest)" tree-planting event organized by the Tokyo Metropolitan Government. "Umi-no-Mori" is an initiative to plant saplings on the inner landfill of the central breakwater in Tokyo Bay, which was reclaimed with garbage and construction soil, and transform it into a beautiful forest to create a venue for the 2021 Tokyo Olympic and Paralympic Games. Umi-no-Mori is expected to serve as a starting point for winds blowing from the ocean to the city center, as well as to absorb CO2, thereby reducing global warming and the heat-island effect. It actually was used as a venue for rowing and canoeing competitions at the Tokyo Olympics and Paralympics.
The Green Feather Fundraising Activity
The purpose of this fundraising campaign is to support Tokyo's forest maintenance, training of forest volunteers, and forest and environmental education for children. We have been making donations every year since 2007.
Efforts to Protect Ecosystems
Volunteer seaside cleanup activities
We have participated in volunteer cleanup activities since 2009. In 2023, 46 employees of our group and their families participated in "Tokyo Satoumi Aid from Nishi-Nagisa," an event to clean up floating garbage in Kasai Marine Park.While Kasai Marine Park is a valuable area in Tokyo where one can experience biodiversity close at hand and was registered under the Ramsar Convention in 2018, it has long been plagued by debris drifting from the Kyu-Edo River and Arakawa River. The event also included a tally of the types and quantities of trash collected to help investigate the causes of the drifted trash. Through this activity, we aim to raise employee awareness of environmental and social issues such as trash reduction and ecosystem conservation.
Efforts in Development Properties
We are working to enhance the planting of trees in our urban development of condominiums and detached houses. In selecting tree species, we have taken steps to ensure that residents can enjoy seasonal changes, and we have taken biodiversity into consideration by including fruit trees. The company also emphasizes harmony with the surrounding natural environment, and at THE Palms Court Hibarigaoka, a detached house, rich plantings form a green network with the adjacent Nishi-Tokyo Ikoi-no-Mori Park, contributing to the preservation of the local ecosystem. In addition, at "THE Palms Yutenji Master Place," a condominium, existing trees have been transplanted to the plaza on the site to create a streetscape that blends in with the surrounding nature without spoiling the greenery of the land.
