Environmental Pollution Prevention Frameworks

To prevent environmental pollution during the course of its business activities, the Yamaha Group has implemented management standards and monitoring and auditing frameworks. We also enact risk countermeasures and conduct drills to prepare for natural disasters, accidents, and other emergency circumstances.

Management Standards and Monitoring

With the goal of reducing the environmental impact of its business activities and ensuring compliance with environmental laws, the Yamaha Group regularly monitors gas, wastewater, noise, odor, and other emissions to confirm the status of the management of these emissions and to assess compliance in accordance with the annual plans created by the Environmental Division of Yamaha Corporation and the management divisions of individual business sites. In monitoring environmental impacts, we employ our own standards, which are stricter than existing legal standards. In the event that measurements exceed standards or are unusual in some way, we take immediate emergency and corrective measures.

In addition, we have systems in place to facilitate quick responses to revisions to laws and regulations. The Yamaha Group collects the latest information on regulatory reforms, and the Environmental Division of Yamaha Corporation compiles, checks, and communicates this information to business sites to ensure consistent compliance on a Groupwide basis. Furthermore, the Group has established working groups at business sites comprised of members of the management and production divisions of the respective sites to advance risk reduction measures. Legal compliance frameworks are developed through coordination with overseas Group companies. Particularly strong coordination is being practiced with companies in China, where environmental laws tend to be amended frequently.

Establishment and Compliance with Environmental Equipment Standards

The Yamaha Group has established the Yamaha Group Environmental Equipment Standards, which contain provisions regarding the installation, management, and operation of environmental facilities. Compliance with these standards is being pursued in a systematic matter based on road maps set on an individual production site basis. In fiscal 2024, we achieved full compliance with these standards for equipment featuring high environmental risks at all domestic and overseas production sites. Going forward, we aim to maintain compliance with these standards in order to keep the number of accidents resulting in environmental pollution at zero.

Environmental Audits

The Yamaha Group conducts internal environmental audits according to the ISO 14001 integrated management system standard in order to prevent environmental accidents and violations of law. In addition, we conduct environmental audits calling on the expert knowledge of the Environmental Division of Yamaha Corporation and in accordance with the Yamaha Group Environmental Equipment Standards. Yamaha auditing staff acquire internal environmental auditor certification based on ISO 14001 standards as well as official qualifications related to environmental preservation, such as Pollution Control Manager and Working Environment Measurement Expert certifications.

Shared Groupwide checklists are used to score compliance with equipment standards at business sites and environmental risks. By clarifying priorities and items requiring a response, the Company is pursuing efficient improvements to mitigate risks.

In addition, the frequency of audits is determined based on risk levels, and audits are conducted regularly. In fiscal 2025, we conducted environmental audits at five sites.

Furthermore, we began conducting voluntary environmental audits of business sites in fiscal 2025. These audits are aimed at ensuring compliance with equipment standards and raising environmental pollution prevention awareness among employees.

Emergency Preparedness

The Yamaha Group implements frameworks and conducts training sessions to prevent environmental pollution caused by leaks of hazardous substances or oils from business sites as part of its efforts to ensure preparedness for emergency situations, such as natural disasters or accidents. The Yamaha Group identifies risks using uniform Groupwide evaluation standards and implements improvement measures and refines procedures pertaining to emergency response measures at business sites deemed to face significant risks through these evaluations. Additionally, business sites have prepared procedures, equipment, and stockpiles to respond to such emergency situations and are conducting emergency response training.

Pollution and Hazardous Substance Response Measures

The Yamaha Group constantly monitors wastewater to prevent wastewater from business sites from negatively impacting the environment through pollution of public waterways, soil, or underground water. Furthermore, we conduct regular surveys on the impact of wastewater on life-forms and the water quality in waterways to which wastewater is discharged. In the past, the Group has conducted cleanup measures at two sites where soil and groundwater contamination occurred due to chlorine-based organic solvents. We have already completed groundwater cleanup activities at the Toyooka Factory. In addition, conditions at Yamaha headquarters have been restored to near-standard levels, and we continue to advance cleanup activities today. We have completed soil contamination cleanup activities at both sites.

At the Toyooka Factory, the Company upgraded wastewater processing equipment in 2018 in order to improve earthquake resistance and processing capabilities. This new equipment can process twice as much wastewater as the previous equipment and has been designed to withstand an earthquake with an intensity of 6 upper to 7 on the Japanese seismic scale.

Waste Disposal Initiatives

• Reduction of specified controlled industrial waste through introduction of waste acid and alkali treatment processes and liquid waste reduction equipment (CD dryers, etc.)
• Augmentation of ability to internally process wastewater containing adhesive agents to reduce waste

Chemical Substance Management and Emission Reduction

Based on the Yamaha Group Chemical Substances Management Standard, the Yamaha Group practices exhaustive management of chemical substances regulated under the Act on Confirmation, etc. of Release Amounts of Specific Chemical Substances in the Environment and Promotion of Improvements to the Management Thereof (the “PRTR Act”) and takes steps to reduce use and emissions of these substances. These precautions are part of our efforts to minimize the negative impact on people and the environment from chemical substance use. At domestic Group companies, safety data sheets^*1 pertaining to materials containing chemical substances are managed in an integrated manner via a database, evaluations of the dangers of these substances and their potential impacts on the environment are performed, and the necessary steps are taken to mitigate risks.

At present, the chemical emissions that occur in the course of production processes at Yamaha Group companies mainly consist of volatile organic compounds (VOCs)^*2 from product coating and adhesive processes. The Group constantly monitors VOC emissions and is working to reduce such emissions by installing treatment equipment and using alternative substances.

Factories in China have completed the introduction of VOC treatment equipment, resulting in a reduction of approximately 90% in emissions of such substances. Meanwhile, PT. Yamaha Music Manufacturing Asia is implementing thinning agent recycling initiatives and has been able to achieve a reduction in emissions of these substances of approximately 70%.

• 1 Safety data sheets are used to record information on the potential dangers and handling methods for chemical substances and products containing chemical substances regulated under the Industrial Safety and Health Act, the Poisonous and Deleterious Substances Control Act, and the PRTR Act.
• 2 VOCs are substances used in thinning agents as coatings and adhesives thought to be one factor in the release of photochemical oxidants and suspended particulate matter.

Reduction of Chemical Substance Emissions in Coating Processes

Coating processes are performed to give musical instruments and automotive interior components their beautiful appearance and durability. In these processes, the Yamaha Group continues to research and introduce coating methods that lower environmental impacts by reducing the use of coating agents and the emission of organic solvents. To date, we have developed applications for electrostatic coating, powder coating, and flow coating matched to our products.

The Yamaha Group has been replacing the coating agents containing organic solvents used for parts with water-based coating agents in the piano manufacturing process. The water-based coating agents are also anticipated to have the positive effect of improving the work environment.

Protection of the Ozone Layer

The Yamaha Group has historically worked to reduce usage of fluorocarbons to protect the ozone layer. We have eliminated the use of all specified chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). After eliminating the use of all specified CFCs in manufacturing processes in fiscal 1994, we began using HCFCs, which have a lower ozone depletion potential compared to specified CFCs, in the degreasing process for metal materials. However, we also eliminated the use of all HCFCs in fiscal 2006 because of its large contribution to global warming.

Environmental Accidents and Litigation

In fiscal 2025, the Yamaha Group did not conduct any serious violations of any laws, receive fines, pay fees, or be named in any lawsuits with respect to environmental concerns. The Group did not experience any accidents having an effect on the outside environment, nor did we receive any significant complaints.
