Promotion Framework and Initiatives

The Yamaha Group promotes sustainability throughout the entire value chain in areas such as product and service development, raw material procurement, manufacturing, selling, and recycling. The Working Group for Procurement and Working Group for Human Rights, DE&I, both of which are chaired by an executive officer, have been established under the Sustainability Committee, which is chaired by the President and Representative Executive Officer. These working groups are responsible for matters related to environmental, human rights, and other supply chain sustainability issues including the establishment of internal frameworks, measures, targets, and action plans; the promotion of initiatives through coordination with the relevant divisions; and the monitoring of these initiatives.

Promotion of Sustainability in the Supply Chain

Yamaha’s Supply Chain

Yamaha produces and sells musical instruments, audio equipment, and a wide variety of other products and their components. These products are primarily manufactured and assembled by Yamaha Group companies with bases in Japan, China, Indonesia, Malaysia, and India, although we also employ the services of manufacturing contractors. The raw materials, components, and other items required to manufacture these products are procured from suppliers around the world.

Initiatives at Group Manufacturing Bases

The status of labor conditions, occupational health and safety, and environmental management at Yamaha Group companies that function as production sites is monitored by dedicated staff members from Yamaha Corporation based on Group regulations and standards. These staff members offer support for developing frameworks and advice for implementing improvements with regard to these matters.

Initiatives Targeting Suppliers

The Yamaha Group has defined policies concerning the procurement of raw materials and components. Suppliers are selected according to the standards set in the Yamaha Group Purchasing Philosophy as the Group seeks to practice procurement in a way that is responsible to the environment and society.

Moreover, Yamaha Corporation participates in the Procurement Committee of the Japan Electronics and Information Technology Industries Association as part of its efforts to promote sustainability in the supply chain through industry coordination.

Yamaha Policies Related to Procurement

Requests for Compliance with the Yamaha Supplier CSR Code of Conduct

Suppliers are asked to adhere to the Yamaha Supplier CSR Code of Conduct, which contains items pertaining to labor, human rights, the environment, and other sustainability considerations. Adherence to the code may be stipulated in basic transaction contracts. If not, documents confirming the consent of suppliers to adhere to the code will be collected. Suppliers of raw materials and parts, goods and services for sale purchased by service and sales companies, and items used and consumed by the Yamaha Group are asked to comply with the stipulations of the Yamaha Supplier CSR Code of Conduct. Consent to adhere to the code has been received from approximately 4,500 suppliers.

In November 2025, the code was revised in response to increasing social demand for respect for human rights and environmental conservation. These revisions strengthened required items by specifying concrete measures that include those that prohibit paying of recruitment fees by workers, expanding the scope of responsible mineral procurement, and setting targets for reducing greenhouse gas emissions.

Assessments of Suppliers

Suppliers are expected to adhere to the Yamaha Supplier CSR Code of Conduct. In addition, paper audits and on-site audits of suppliers of raw materials and components, among other suppliers, are conducted prior to commencing transactions with a new supplier and regularly thereafter. Under the medium-term management plan “Rebuild & Evolve,” Yamaha has adopted on-site supplier audits of 60 companies as a target.

Key Non-Conformance Issues Identified During Assessments

Paper Audits (SAQs)

No health and safety training; employment contracts written in language other than employees’ native language; payment of recruitment fees by workers; lack of confirmation of environmental regulations; lack of confirmation of occupational accidents involving subcontractors

Additional Paper Audits of Companies in Malaysia

Retention of passports or other identification documents; insufficient space in dormitories; lack of explanation regarding pay deductions

On-Site Audits

Retention of passports or other identification documents; expiration of business licenses; insufficient management of employment contracts, attendance records, or payment records; non-conformity with minimum wage or working hour regulations; lack of evacuation routes or disaster prevention equipment at dormitories or other facilities; inappropriate management of hazardous or chemical substances; insufficient grievance mechanisms

Response to Claims and Reports of Human Rights Violations in the Supply Chain (Grievance System)

The Yamaha Group is proactive in its response to consultations and reports regarding human rights violations across the supply chain. For example, we joined the Japan Center for Engagement and Remedy on Business and Human Rights (JaCER) in October 2022 and are accepting claims filed through its Engagement and Remedy Platform. As of March 31, 2026, the Company had received four reports of human rights violations (two through the JaCER platform) and took measures in response to these reports. Going forward, we will continue accepting reports through this platform while promoting understanding regarding the platform.

Training and Education

The Company is committed to education and training programs to promote responsible procurement practices that take into account environmental and social impacts. The Yamaha Group promotes internal training on topics that include the Act on Ensuring Proper Transactions Involving Specified Entrusted Business Operators (the “Proper Transactions Act”), laws related to contracts, and various regulations related to trade and procured goods. In addition, the Group provides training on preventing and reducing the negative impact in the supply chain on human rights and the environment. In fiscal 2026, under the Procurement CSR Training program, 500 employees in procurement-related divisions across domestic and overseas Group companies completed e-learning courses, while 220 practitioners and other relevant employees attended seminars covering practical content. Briefings related to sustainable timber procurement, which include confirmations of timber legality, are held each year for employees involved in procurement of timber. In addition, e-learning modules on the theme of business and human rights were made available to employees via the Company’s intranet. More than 1,000 employees deepened their understanding of human rights and environmental risks across the supply chain, as well as trends in relevant laws and regulations.

Meanwhile, suppliers are requested to demonstrate environmental and social responsibility by adhering to the Yamaha Supplier CSR Code of Conduct and SAQs. In fiscal 2025, external instructors were invited to conduct workers’ human rights seminars for suppliers in Japan focused on the measures that can be taken in relation to business and human rights. Going forward, Yamaha plans to roll out other e-learning materials with specialist topics related to responsible procurement, including overseas suppliers.

Responsible Raw Material Procurement

In the procurement of natural resources and other raw materials, it is important to practice responsible procurement out of consideration of the potential impacts on the environment and society. The Yamaha Group is focused on themes that include green procurement and the sustainable procurement of timber, an important material for instruments and other products.

Responsible Mineral Procurement

The Yamaha Group works to procure minerals that play no part in the violation of human rights or environmental destruction. We respond to customer requests to conduct due diligence activities, and also ask suppliers to take similar steps based on the Yamaha Supplier CSR Code of Conduct.

Policies were revised in fiscal 2026 and the scope was expanded to cover additional minerals beyond tin, tantalum, tungsten, and gold. The Yamaha Group has been working together with suppliers to conduct surveys using the Conflict Minerals Reporting Template (CMRT) and Extended Minerals Reporting Template (EMRT) of the Responsible Minerals Initiative (RMI). The Group is currently aggregating and analyzing the results of these surveys.

Communication with Business Partners

The Yamaha Group promotes communication with business partners and subcontractors. In Japan, we share information about management, production, and sales trends to suppliers that provide us with raw materials, parts, and equipment and to subcontractors that supply distribution, construction, and other services. We also work together with these partners to contribute to worker safety and environmental conservation while striving to foster an atmosphere in which it is easy to share thoughts through relationship-building activities. Furthermore, we confirm the status of compliance and CSR measures at the waste treatment subcontractors used by domestic production sites through site visits and other measures. We have also joined the Shizuoka Industrial Waste Association of Shizuoka Prefecture, where we have production sites, as a waste producer. As a member of this organization, we engage in communication through exchanges of waste treatment information and support for facility tours and other events.

Partnership Declaration

Yamaha Corporation has announced its Partnership Declaration, which details its commitment to building harmonious partnerships with suppliers to heighten value across the supply chain.
