Tree Planting and Pruning Volunteer Program Conducted at Mitsui's Forest (Sando Forest)
On November 12-13, 2025, 18 Mitsui & Co. employees participated in a tree planting and pruning volunteer program at Sando Forest in Kitamuro District, Mie Prefecture, with the aim of deepening their understanding of natural capital.
Mitsui & Co. owns forests in 76 locations across Japan, covering a total area of approximately 45,000 hectares—equivalent to about 0.1% of the country's land area. Among these forests, the Sando Forest is the largest and oldest company-owned forest in Honshu.
On the first day, participants were divided into three groups and worked on steep slopes, carefully leveling the ground with hoes around tree stumps and rocks before planting seedlings one by one. Under the guidance of employees and officer of Mitsui Bussan Forest., which manages Mitsui's Forest, participants worked diligently and successfully achieved the target of planting 1,200 trees.
On the second day, participants again worked in three groups to carry out pruning activities. After identifying the appropriate trees for pruning and working collaboratively, they successfully completed the planned work area.
We recognize natural capital as one of the key sustainability issues in our management strategy. Through this program, participants deepened their understanding of natural capital, including the importance of forest conservation and the preservation and enhancement of biodiversity, while also strengthening relationships with colleagues from different departments and employees and officer of Mitsui Bussan Forest. The experience provided an opportunity to gain firsthand insight into both the importance and challenges of addressing environmental and social issues.

Vietnam: Clean-up Initiative


On October 14, 2023, Mitsui Vietnam participated in the "Collect & Connect" beach cleanup initiative at Dinh Cau Beach on Phu Quoc Island as part of its environmental conservation activities.

All participants were pleased that they were able to contribute to the local community, as the initiative also helped to improve beach safety, protect coastal ecosystems, and support the local tourism industry. Mitsui Vietnam will continue to contribute to local communities in Vietnam, both through its business and through activities involving employee participation.
Taiwan: Mountain Clean-up Initiative

Taiwan, characterized by its predominantly hilly and mountainous terrain, is home to 268 mountains over 3000 meters. In a bid to foster greater appreciation for the beauty of Taiwan's mountains, restrictions on access to mountain forests were lifted in October 2019, and a multitude of initiatives are underway to preserve the mountain environment, including in the areas of education and infrastructural development. Mitsui Taiwan's headquarters is located in Taipei, which is a basin surrounded by many mountains. Every year, newly recruited employees of Mitsui Taiwan organize a mountain clean-up initiative as a way to promote employee well-being and unity within the company. Accompanied by their family members, employees embark on a hike up the mountains, collecting litter along the way. In 2023, 28 people, including CEO, employees, and employees' families, attended the event. Mitsui Taiwan will continue to actively engage in community contribution initiatives.
