This report is designed to inform our stakeholders—all those with a vested interest in Mitsubishi Materials and the Mitsubishi Materials Group—about the corporate social responsibility (CSR) activities undertaken by the Mitsubishi Materials Group in an easy-to-understand format so as to promote a greater awareness and appreciation of the Group’s efforts.
The articles featured in this report focus primarily on the nine areas selected as part of the process of identifying material issues in fiscal 2008. Other areas covered in this report include our new Medium-Term Management Plan, which came into effect in August 2011, and initiatives aimed at rebuilding following the Great East Japan Earthquake.

Rather than merely reporting on our activities, we regard the disclosure of CSR-related information to be an important process in terms of the evolution of our CSR activities, not least through the monitoring and performance reviews of our individual initiatives. We therefore make every effort to improve the information that we disclose in order to ensure that our reports are as reliable as possible in accordance with Global Reporting Initiative (GRI) Guidelines, as part of our disclosure activities as a member of the International Council on Mining and Metals (ICMM). Ever since the 2010 edition, we have also had our CSR Reports independently assured by KPMG AZSA Sustainability Co., Ltd.
Full details of activities undertaken by our Metals Company, which is directly responsible for ICMM activities such as these, are available online via the Metals Company Supplementary Data Book, which should be referred to in combination with this report.
