Shin‐Daibiru Building
The Shin-Daibiru Building Dojima-no-mori Garden (lit. “Dojima Forest”) carries on the spirit of the rooftop tree garden of the former Shin-Daibiru Building. In addition to transplanting some of the 50-year-old trees from the old rooftop tree garden, hich included Japanese maples and elms, we created a 3,300 m² green space, roughly the same size as the previous garden, using mainly native species. Biodiversity monitoring surveys conducted by external agencies in fiscal 2016, 2020, and 2024, after the completion of the Shin-Daibiru Building Dojima-no-mori Garden, confirmed that a stable food chain had been established within the forest. A habitat in the urban area like this is precious for birds and insects, and its contribution to the ecosystem was highly evaluated.

Promotion of Conclusion of Green Lease Agreements
"Green lease" refers to the voluntary agreement on the cooperative promotion of environmentally friendly initiatives such as the reduction of energy consumption and waste and the acquisition of environmental certifications by building
owners and tenants reached by concluding lease contracts, etc., and the implementation of such initiatives.
GOR promotes the incorporation of green lease clauses into lease contracts as an endeavor on conservation of energy and CO₂ emissions reduction in cooperation with tenants.
-
The KPI for the conclusion of green lease agreements was changed from “Implementation rate in new contracts” to “Implementation rate in all contracts” in fiscal 2022.
In fiscal 2025, the implementation rate in new contracts was 100% (excluding master lease agreements) and the implementation rate in all contracts was 55.8%.
Cooperation with Business Partners
