Tokyo Seimitsu publishes its Sustainability Report on its website to help all stakeholders understand the Group’s sustainability initiatives and ensure better communication with them.Since 2025, we have quit providing the “Sustainability Report” in paper form. The report is now available only in the Sustainability section of our website.The Sustainability page is updated not only on an annual basis (in September) but also as needed in order to disclose information in a timely manner.The latest update information is posted on the “News” page of the Sustainability section as the information is updated.
We publish the “Sustainability Report” every year based on the information posted on the Sustainability section of our website as of November of that year.The previous Sustainability Reports can be viewed from “Sustainability Library.”
In addition to the Sustainability section of our website, our annual reports include the Integrated Report that mainly covers short-, medium-, and long-term strategies and the direction in which management intends to go, and the securities report that mainly provides financial reports. These reports are complemented by the corporate site containing the most up-to-date information.
