Decarbonization, transitioning to a circular economy, and co-existence with nature are among the goals which the Marubeni Group pursues through its business activities. The Marubeni Group will also strive to achieve these goals through our social contribution activities.
On Saturday, November 22, 2025, Marubeni’s Kyushu Branch and Karatsu City co-hosted a volunteer beach cleanup event at Hamasaki Beach. Twenty-nine employees and family members from the Kyushu Branch and six Marubeni Group companies, along with approximately 20 representatives from Karatsu City and local NPOs, participated in collecting and sorting beach litter. Following the cleanup, a report on the results of a biological and water quality survey for Hamasaki Beach was presented. This provided participants with an opportunity to understand the current state of the beach’s water and heightened their awareness of issues local waterfront areas face.During the cleanup, participants came across many plastic items and empty cans, helping them to recognize the severity of problems caused by beach litter and microplastics. Many expressed a desire to continue these cleanup activities, having gained a tangible sense of contributing to the community through collaboration with the city government and local NPOs. Marubeni’s Kyushu Branch will continue its ongoing environmental conservation activities in partnership with the local community.
In August 2024, the planted garden area surrounding the first floor of the Marubeni Building (the Tokyo Head Office), called Kurenai Grove,* was certified as an “Excellent Green Space” and registered in the “EDO-MIDORI Registered Green Spaces,” a native species planting registration system implemented by the Tokyo Metropolitan Government.The “EDO-MIDORI Registered Green Spaces” is a system in which the government registers and publicizes green spaces where native species are actively planted along with the efforts being made to conserve biodiversity. Green spaces that are particularly excellent in terms of being considerate of the habitats of native fauna are registered as “Excellent Green Spaces.”Kurenai Grove is a green space that was created to harmonize and connect with similar spaces in surrounding areas, such as the paths around the Imperial Palace and the Nihonbashi district. The space is a combination of high, overlapping tree canopies, which create a large foliage cover, with mid- to low-height shrubs and ground-level plants beneath them. Most of the plants are native Japanese species, such as the mochi tree (a species of holly) and the Japanese camellia, in consideration to native biodiversity. This layout aims to contribute to the formation of an ecological network connecting the Imperial Palace and surrounding green spaces.

Marubeni Osaka Branch joined Osaka Prefecture’s Adopt-a-Forest, an afforestation and forest maintenance initiative, in 2006, and has participated in forest maintenance activities in Kounoyama since then, including signing a “Marubeni’s Forest” declaration in December 2011 together with Osaka Prefecture, Kishiwada City and Kounoyama Conservation Club. In December 2017, Marubeni received a letter of appreciation from Osaka Prefecture, in recognition of its long-term commitment to this initiative.
