The Mitsui Fudosan Group owns roughly 5,000 hectares of forest (equivalent to 1,063 Tokyo Domes*) in 31 cities, towns and villages in Hokkaido. Over 60% of these forests consist of planted Sakhalin fir, and we are conducting planned planting and appropriate management and cultivation. Thinned and regular timber from these forests is used as material for construction, furniture, and other purposes, encouraging forest renewal and "never-ending forests."
The remaining nearly 40% of trees are natural Mongolian oak and other species. These trees are managed minimally to preserve them as much as possible in their natural state.
*Calculation based on Tokyo Dome covering 4.7 hectares.
In July 2017, Mitsui Fudosan and Minato Estate Co., Ltd., which cultivates and manages forest land, concluded an agreement with Shimokawa Town, Hokkaido, to engage in comprehensive coordination to create a sustainable regional society based on never-ending forests.
To preserve the upper reaches of the Tama River for the future, the Tokyo Metropolitan Government Bureau of Waterworks has formulated a plan to involve average citizens in creating water conservation forests. Creating forests with citizens, enterprises, and many others promotes understanding of the importance of preserving water resources. Mitsui Fudosan agrees with the goals of this plan. In June 2017, it acquired naming rights for one part of Tokyo Waterworks: Enterprise Forest from the Bureau of Waterworks, and in collaboration with the bureau, implemented a forest preservation work experience program for Group employees. Through this and other program features, the Mitsui Fudosan Group is working to preserve water conservation forests.
In 2017 and 2018, at the Mitsui Fudosan & EARTH FOREST TOKYO in Koshu City, Yamanashi Prefecture, we gave Group employees first-hand experience in forest preservation.
As preparation for tree planting, six Group employees participated in ground clearing activities in November 2017, collecting fallen branches, underbrush and other forest detritus. In June 2018, 11 employees participated in planting seedlings in the same location.
Working with personnel from the Tokyo Metropolitan Government Bureau of Waterworks, participants gathered fallen branches and timber.
Healthy forests absorb and store water and help prevent flooding and landslides. They also have other benefits, such as mitigating global warming and preserving the biosphere. In collaboration with the Tokyo Metropolitan Government Bureau of Waterworks, we visited the forest and experienced work activities relating to water supply and the sense of mission that comes with such work. This experience reminded me of the importance of water resource-promoting forests. As a water user, I felt motivated personally to do more than simply use less water to protect water resources. I hope to continue my research and planning to share this outlook with as many employees as possible.
