Respecting Human Rights

Respecting human rights

Basic approach
The HOYA Group respects the human rights of all officers and employees of the HOYA Group and all stakeholders involved in the business activities of the Group. The Group advances efforts on human rights in accordance with the UN Guiding Principles on Business and Human Rights.

HOYA Global Code of Conduct
The HOYA Global Code of Conduct stipulates the basic guidelines to be complied with when performing operations based on the Corporate Mission and values of the HOYA Group. The Code of Conduct clarifies that basic human rights are to be respected and that all forms of discrimination and harassment in connection to race, nationality, gender, religion, belief, birthplace, age, or disabilities are to be eliminated in all corporate activities, and that child labor, forced labor and human trafficking are prohibited. We aim to create a safe and healthy workplace that allows employees to feel secure while they work. The Company will provide equipment, systems, and working conditions so that each and every employee respects and cooperates with each other as the Company strives to create a workplace that is easy to work in.

The HOYA Group takes rigorous measures to ensure Group-wide understanding of its stance on human rights. The Group translates the Code into 27 languages in view of the status of its global operations, conducts e-learning once a year for all Group employees and tests participants to ensure that they understand the content. We also conduct internal audits to confirm that the procedures described above are followed. Confirmation notices regarding strict compliance with the Code of Conduct for all Group employees were submitted with a 97% submission rate in fiscal 2022.

HOYA Group Human Rights Policy
In October 2022, with the approval of the Board of Directors, the HOYA Group established the HOYA Group Human Rights Policy, spelling out the Group’s stance on respect for human rights in accordance with the Group’s Corporate Mission and Management Principles. The policy includes in its scope all of its partnerships with stakeholders and commits the HOYA Group to complying with a number of international principles and guidelines, including the UN International Bill of Human Rights, the International Labor Organization (ILO)’s ILO Declaration on Fundamental Principles and Rights at Work, the UN Guiding Principles on Business & Human Rights (UNGPs), and the 10 Principles of the UN Global Compact.

Based on the Human Rights Policy, the Group puts its respect for human rights into practice by five means:
・Conducting due diligence on human rights
・Relief measures
・Dialogue with stakeholders
・Awareness-raising activities and education
The Policy on Human Rights is published on the HOYA Group website in Japanese and English and all stakeholders are made aware of it.

Framework for Promoting Response on Human Rights
Under the authority of the Chief Sustainability (ESG) Officer, the ESG Promotion Office at Group head office coordinates with the Compliance Department, Legal Department, Personnel Department, and other related departments in the head office, proposing policies and plans for the entire Group on human rights and confirming progress in a timely manner. In addition, the Chief Compliance Officer (CCO) oversees an organizational framework for managing compliance risk globally. The CCO responds to the full range of compliance issues, including labor-related compliance, human rights-related issues such as consumers’ (patients’) rights to be safe and informed, protection of privacy and management of personal information, corruption and bribery. On a regular basis, the CCO reports its activities and progress to the Board of Directors and reflects feedback from the Board of Directors in activities.

Due Diligence on Human Rights

Identifying Human Rights Issues (Negative Impacts)
To assess human rights risks in its value chain, the HOYA Group selected four divisions and obtained professional opinions from outside experts on each of them in fiscal 2022. Selected for the details of their operations and other factors, the four divisions are the Eyeglass Lens Division, the Medical Endoscope Division, Semiconductor Mask Blanks Division, and the HDD Glass Substrate Division. The Group also referred to outside data on international compacts and guidelines*1 related to human rights, industry attributes, country risks and so forth, as well as results of hearings with business divisions and other related departments in Group head office. Through these efforts, the Group discovered and categorized potential issues and risks on human rights for each stakeholder.

*1 These include the UN International Bill of Human Rights, the ILO Declaration on Fundamental Principles and Rights at Work, the 10 Principles of the UN Global Compact, and OECD Guidelines for Multinational Enterprises.

Identification of Human Rights Issues for Each Stakeholder
As a result of the human rights risk assessment, the Group identified potential human rights issues related to each stakeholder in our value chain. In addition to continuing efforts to enhance understanding of the Codes of Conduct and educational and training measures to prevent harassment, the Group is intensifying existing measures and augmenting them with additional approaches. Going forward, the Group intends to build and reinforce a framework for human rights due diligence extending to all stakeholders throughout the value chain, from those within the Group to suppliers, for example through the use of questionnaire surveys.

Corrective and Complaint Processing Mechanisms
As part of its internal control systems, in 2003, the HOYA Group launched the HOYA Help Line, a service for receiving Group-internal whistleblowing reports and requests for advice. With outside consultation services established in each country, the HOYA Help Line makes it easy for employees to seek advice. Inquiries are accepted online round-the-clock in multiple languages; employees can receive consultation in their local languages and report issues anonymously. The Group has drawn up rules of operation for the HOYA Help Line that are fully legally compliant, protects whistleblowers and prohibits retaliation against them, and maintains confidentiality to ensure anonymity. In fiscal 2022, there were 170 whistleblowing complaints made to the HOYA Help Line, of which 54% were related to the workplace environment and 25% were related to HOYA’s system. In fiscal 2022, there were no whistleblowing incidents inflicting a serious impact on HOYA’s businesses.

For business partners outside the HOYA Group, HOYA fields inquiries about the HOYA Supplier Code of Conduct, establishes contact points for whistleblowing, and conducts surveys and responses appropriately to protect whistleblowers and their information.

Employee Education and Training
Once a year, the HOYA Group conducts e-learning and tests all Group employees on their knowledge of the HOYA Global Code of Conduct, ensuring thorough circulation of information within the Group. On harassment, the Group has formulated the HOYA Group Policy and Guidelines on Measures to Prevent Harassment. This document discloses measures and policies to prevent harassment, protect respect for each employee as an individual, and prevent disruptions to workplace discipline and barriers to work. Based on these Guidelines and the laws and ordinances of each country, the Group provides all Group employees with education and training on measures to prevent harassment; in Japan, this training is tailored to each level of management. In fiscal 2021, 97% of employees in Japan underwent training on measures to prevent harassment and were tested on their knowledge of the subject.

Supply Chain Measures
The HOYA Group asks all of the business partners who supply it with products and services to maintain the same level of compliance and ethical conduct that the Group does. With this aim in mind, the Group prepared the HOYA Supplier Code of Conduct. All suppliers are required to accept, sign and comply with this Code of Conduct. The HOYA Supplier Code of Conduct calls on all suppliers to prohibit forced labor, child labor, discrimination, harassment, corruption and bribery, and to uphold the principles of freedom of association and right to collective bargaining and secure occupational health and safety. To ensure responsible mineral procurement, the Group conducts surveys on conflict minerals and sets targets for suppliers’ rate of response to the survey and the number and percentage of smelters that are compliant with the Responsible Minerals Assurance Process (RMAP). On the basis of these targets, the Group monitors results and promotes efforts to reduce risk associated with conflict minerals.

Measures to Ensure the Safety of Consumers (Including Patients)
o strengthen its product safety management system, the HOYA Group must ensure rigorous compliance with the standards required of healthcare products in Japan and overseas, laws and ordinances governing product quality and safety, and other norms. For this purpose, in fiscal 2022, the Group launched the Healthcare Compliance Committee, composed of independent directors. The Group obtains objective advice from these independent directors and, when needed, from experts versed in the laws and ordinances of particular countries, as it carries out activities to secure product safety, led by an officer responsible for regulatory compliance.

For details please see “Product Safety Assurance Policy and Structure.”

Protecting Privacy and Managing Personal Information
The HOYA Global Code of Conduct declares the Group’s respect for individuals’ right to protection of privacy and stipulates prudent management of personal information. To prevent information leaks by improving HOYA Group employees’ security mindset, the Group provides cybersecurity training on a regular basis, using e-learning. In 2022 the Group adopted a basic policy for the handling of personal numbers and specified personal information and made clear its stance of strict compliance with related laws and guidelines. In these ways the HOYA Group is working to prevent problems related to the handling of personal information.

Grappling with Bribery and Corruption
Based on the HOYA Global Code of Conduct, in 2021, the HOYA Group moved to strengthen measures to prevent bribery and corruption by instituting the Anti-Bribery and Anti-Corruption Policy. This policy establishes rules for preventing bribery and corruption and stipulates measures such as formation of an internal management framework and provision of training. The Group is also continuing to provide employees with education on these issues.
