Our Approach to Material Issues

Identifying and Reviewing Materiality (Material Issues)

We recognize that the sustainability of society as a whole will always have a significant impact on our corporate activities in the future. That is why we identify high priority issues from the point of view of management. Once we have identified these material issues, we incorporate them into our business activities, and disclosed details and the results of our initiatives in our Sustainability report.
Initially, in fiscal 2008, we identified nine material issues of the Group by conducting a material issue assessment based on the framework of the GRI Guidelines, a set of international guidelines that address sustainability reporting. In fiscal 2016, we reorganized them into seven issues. Later, in response to changes in the external environment, we updated the Group's material issues in the Medium-term Management Strategy for the period until fiscal 2023, which we announced in March 2020. As a result, the Group now has ten material issues.
In addition, in the Medium-term Management Strategy FY2031 that was announced in February 2022, we employed the following selection process to identify key factors from various perspectives and arranged these elements along two axes, in terms of their importance for each stakeholder, and their degree of importance in relation to Our Commitment. Following extensive discussion on the importance of each key factor undertaken by the Strategic Management Committee and the Board of Directors, an order of priority was established. As a result, we set ten material issues that include four key material issues regarded as being of particularly high importance.

Selection Process
STEP1.
Identification of issues
Extracted key factors from among those identified from the perspectives of ESG and sustainability in 2015 in light of information such as GRI indicators, the OECD Guidelines for Multinational Enterprises and SRI categories. We identified social issues from the perspective of social, environmental and economic trends, trends in markets related to the Company, and initiatives undertaken by the Group to increase our corporate value in the medium-to long-term. We also considered international guidelines and principles when selecting elements of these issues.
STEP2.
Organization and assessment of issues
In addition to these elements of social issues, we set two axes on which to rank our material issues, including those established in fiscal 2021: the importance to our various stakeholders, and the importance in light of Our Commitment.
After all of our Executive Officers and Directors have organized the issues and key themes, they are discussed from the perspective of their importance to our stakeholders and the Company.
STEP3.
Selection of issues
The material issues and key themes established in fiscal 2021 are revised and redefined, with priority given to issues that are ranked as “very high” or “high” on both axes.
We have designated four key material issues that are of particular importance.
STEP4.
Establishment of nature and objectives of initiatives
The nature and objectives of initiatives to address the redefined material issues and key themes are established.
The progress and results of these initiatives are regularly disclosed.
