Editorial Policy

The Sumitomo Forestry Group publishes the Sustainability Report as an important tool for communicating with various stakeholders about its activities aimed to contribute to the creation of a sustainable and prosperous society.

Based on the principle to promote sustainable management, we are enhancing our information disclosure systems using the ESG (environmental, social and governance) framework, while striving for further integration of business and ESG strategies according to the basic policies of our medium-term managemnt plan "Mission TREEING 2030 Phase 2" started in 2025 following "Mission TREEING 2030 Phase 1."
This report describes the fiscal 2025 results of our "Mid-Term Sustainability Targets Phase 2 (2025–2027)," along with the related sustainability activities.

Our sustainability website is updated with the latest information on an as-needed basis, and the Sustainability Report (PDF) is published once a year. In addition to this, we issue a pamphlet carrying highlights of our unique sustainability initiatives. We hope each reader will choose any of these options according to their interest as stakeholders.

Furthermore, we publish the Integrated Report to present our annual performance and efforts to improve corporate value in a medium to long term.
