HOYA’s ESG Approach
ESG and Sustainability Governance Framework
Governance
HOYA is organized as a company with Nomination Committee, etc. As such, the Board of Directors functions as a monitoring board, supervising the executive side and deliberating and deciding on materialities in management policy Group-wide. To secure management supervisory functions and ensure their objectivity, in fiscal 2024 the Company established a framework in which five of seven directors are outside directors. We appoint outside directors with extensive executive experience and a global perspective, who also possess deep knowledge of sustainability and ESG-related fields, as well as a clear understanding of emerging trends—including climate change, talent development, and leadership development—and practical experience in these areas.
The Group's basic sustainability policies, including climate change countermeasures, materiality, and important measures such as TCFD and RE100 are disclosed through deliberation and decision-making procedures by the Board of Directors. In addition, the Board of Directors receives regular reports on issues related to sustainability, including responses to climate change, from the Chief Sustainability Officer (twice a year in fiscal 2024), and monitors progress. The Board of Directors' receives reports on climate change responses in each business division during business reviews at Board of Directors meetings and provides advice from multiple perspectives. Similarly, the Group CHRO reports regularly to the Board of Directors regarding personnel measures across the HOYA Group, and the Group CCO reports regularly to the Board of Directors on compliance (once a year in fiscal 2024).
At HOYA, we conduct business operations through a divisional management approach facilitated by portfolio management. As such, each business division’s specific policies on responding to sustainability-related issues, including climate change and human capital, are reflected in the management strategy, management plan and annual budget of each business, to be approved and decided by the Board of Directors. Additionally, each business division’s head (division president) appoints a sustainability/ESG team within their division. Under the direction of the division head, the division’s KPIs, aligned with the Group’s goals, are set in consultation with the CSO. The division then implements measures to achieve these established KPIs.
In fiscal 2022, ESG indicators were incorporated into the Performance Share Unit (PSU), serving as a medium- to long-term incentive in executive officers’ remuneration. Targets are set according to evaluations by outside organizations and the status of efforts on key ESG themes, including climate change and human capital. In fiscal 2023, to enhance the effectiveness of these indicators, important KPIs among the key ESG-related targets set by each business division, such as renewable-energy usage rate, were added to the criteria for annual incentives of the presidents of each business division.
Risk management
At the HOYA Group’s head office, we appoint persons responsible for functions considered to pose significant risks, including compliance, pharmaceutical regulations affairs, cybersecurity, and occupational safety and health. Each business division identifies and mitigates risks through the persons responsible for these respective functions.
The responsible persons at the HOYA Group’s head office regularly monitor the activities of the business divisions concerning their respective areas and report to the executive officers on the identification and response status of significant risks. Based on these reports, the overall risk status of the Group is presented to and deliberated by the Board of Directors.
Each business division formulates response policies for significant risks that could have a serious impact on its operations, tailored to its specific business environment and characteristics. Preventive measures for these risks are incorporated into the division’s strategies, business plans, and annual budgets, and are subject to regular oversight by the Board of Directors.
When business division heads present their operations to the Board of Directors, they receive multifaceted questions from outside directors regarding risks specific to their businesses, such as geopolitical and procurement risks. These discussions provide valuable opportunities to deepen risk awareness.
Each business division has an internal audit function that identifies risks through the audit process. In addition, the internal audit department at the Group’s head office develops a risk-based audit plan, which is approved by the Audit Committee. Audits are conducted accordingly, and the results are reported to the Audit Committee. The content of these audits is regularly reported from the Audit Committee to the Board of Directors, thereby ensuring objective risk management through an independent oversight body.

Material Issues
Having internally discussed and examined matters that contribute to the HOYA Group’s medium- to long-term growth (i.e., material issues), we identified four material issues with the approval of the Board of Directors in September 2021. In light of emerging disclosure standards such as the Corporate Sustainability Reporting Directive (CSRD), the International Sustainability Standards Board (ISSB), and the Sustainability Standards Board of Japan (SSBJ), the HOYA Group is currently reviewing its material issues. Going forward, we aim to further enhance the integration and transparency of our sustainability-related disclosures.
Process of Identifying Material Issues

Get a grasp of changes in society and issues related to HOYA’s businesses.
Analyze ESG rating agencies’ evaluation of HOYA and refer to international guidelines.*1
Interview the management of business divisions.
Use the industry-by-industry Materiality Map*2 by SASB*3 that matches HOYA’s businesses and select the candidate issues based on evaluation on two axes, i.e., by mapping stakeholders’ interest on the vertical axis and the impact on HOYA’s businesses on the horizontal axis.
Conduct an evaluation comprehensively by deepening internal discussions while referring to opinions and feedback obtained from investors in and outside Japan who are key stakeholders.
Obtain approval for the identified four material issues at the Board of Directors’ meeting.
*1. SASB, GRI, IIRC, ISO26000, TCFD, RBA, CDP
*2. Industries: Medical Equipment & Supplies, Hardware, Semiconductors
*3. Sustainability Accounting Standards Board
