The Seibu Group is engaged in various initiatives focused on protecting biodiversity and has signed onto the Declaration of Biodiversity by Keidanren (Japan Business Federation). The Group companies have been taking steps to reduce plastic waste due to its harmful effects on marine life and ecosystems. For example, they have banned plastic straws on their premises and are progressively shifting to paper straws. Disposable plastic bags have also been discontinued and we propose non-use of amenities in guestrooms at Prince Hotel.
Seibu Realty Solutions has hotel facilities in national parks across Japan, such as Fuji-Hakone-Izu National Park and Joshin’etsukogen National Park.
In 2018, the Group concluded a partnership contract with the Ministry of the Environment in the National Park Official Partnership Program. That has further promoted our engagement in business activities that take into consideration regional vitalization and nature/biodiversity environmental protection. In Furano, we also offer a former golf course to NPOs for tree-planting activities aiming to give back to nature. At Tokyo Garden Terrace Kioicho we preserved and transplanted about 200 trees which had been planted on the site during the period of the former Grand Prince Hotel Akasaka. We planted 340 new trees (over 3m) to form green urban spaces from the beginning of the building completion. Additionally, by planting more than 200 species of plants, the green area ratio for the site is approximately 45%. We aim to develop a community that will contribute to building an ecological network (green corridor) aligning with valuable urban green spaces in the Imperial Palace and Akasaka Goyochi Palace grounds, etc. At the center of the site, there is a road surrounded by greenery which we call a "green axis" that runs from the adjacent Benkei moat to Shimizudani Park. We also create a biotope in the area called “Forest of Lights” in the north side of the site.
In addition, each group company is taking various initiatives to preserve biodiversity.

• Yokohama Hakkeijima and Taiwan Yokohama Hakkeijima breed rare species and rescue and conserve injured wildlife.
