Thorough compliance policies

All Mie Plant employees are issued with “compliance cards” and are familiarized with the Yokohama Rubber Group compliance guidelines, and with the availability of contact points for discussing compliance-related issues.
Compliance and Labor Union Representative committee meetings made up of managers are held monthly to report workplace inspection results, share information, and consider and implement stratified training.

Organizational self-corrective functions

We established a suggestions box in the plant’s cafeteria, enabling us to receive feedback from employees. In addition, as we continue to operate the employees' web-based consultation service, which was established independently by the Mie Branch of the labor union, we carefully handle the opinions and requests we receive and continue to work with the Mie Branch of the labor union to make the service useful for the sound management of the organization.
In addition, we conducted compliance training for managers and supervisors twice a year.

Education on respect for human rights

We distribute compliance cards to employees and promote the importance of respecting human rights.

The basics of safety and health

In 2006, the Mie Factory acquired OSHMS (Occupational Safety and Health Management System) certification based on the JISHA (Japan Industrial Accident Prevention Association) method and has been promoting activities. Aiming to be a company with high.
We became the first domestic factory to obtain JISQ45100 certification in July 2024. We will promote this with the aim of improving social credibility, improving employee satisfaction, and strengthening market competitiveness. The factory's safety and health policy states, ``Ensuring the safety and health of workers is the basis of everything, and in order to prevent industrial accidents and create a workplace that is healthy and comfortable for both mind and body, we strive to improve occupational safety through consultation and participation of workers. We will implement and operate the hygiene management system appropriately and effectively, and build a workplace culture in which everyone prioritizes safety and health above all else.

Creating safe equipment

Using risk assessment methods, we are promoting the identification, evaluation and improvement of potential danger sources; we are also implementing measures that include the isolation of sources for danger from work areas and promoting the creation of people-friendly facilities.

Safety awareness

We pursue safety as a top priority under all circumstances. Specifically, we have shifted from collective guidance to individual guidance, and we conduct one-on-one safety education, dedicated safety time activities, and reviews of work procedures in open work observation.
In addition, we view successor development as a priority issue, and we are working to improve skills through various types of training.
We conduct activities suitable for the mind of each and every individual through thorough decluttering and organizing and the revitalization of communication.

Creating energetic workplaces

We publicly recognize and reward employees for positive contributions, regardless of their position or employment status, through various forms of recognition, even for small achievements. We also encourage employees to take risks and embrace challenges, which has led to numerous proposals and improvements originating from the field.
The Mie Plant slogan, "Returning Home with a Smile Every Day," emphasizes that the "health of mind and body" of each employee is fundamental. To promote health, we utilize a health app. Labor and management jointly plan and participate in "walking events" linked to the app, allowing employees to enjoyably improve their health awareness and address lifestyle-related diseases.
As part of our efforts to reduce smoking rates, we designate a Smoke-Free Day on company premises each month.
Additionally, we offer programs to support those who wish to quit smoking and conduct seminars by external organizations to promote smoking cessation.
To address employee mental health, we conduct and improve various workplace environment assessments. Labor and management jointly verify the effectiveness of these measures and work towards further improving the workplace environment. Furthermore, we collaborate with external organizations such as the Ise City Health Department and the Japan Industrial Safety and Health Association to provide mental health care education, promoting a workplace where all employees at the Mie Plant can work "brightly, happily, and energetically."

Employment of people with disabilities

To expand employment opportunities for people with disabilities, we are strengthening our relationships with special needs schools and other related organizations. In 2024, we conducted six internships, with four students participating. As of the end of December 2024, we employed 22 people with disabilities, representing an employment rate of 2.53%. We will continue to work towards expanding employment opportunities for people with disabilities.

Reporting on chemical substance management status

For all substances handled at our plant (raw materials, auxiliary materials, and supplies), we verify the presence of applicable chemical substances using Safety Data Sheets (SDS). For substances handled in quantities specified by the PRTR Law, we conduct annual reporting to the national and prefectural governments, as well as a safety impact assessment. Please refer to the Safety Assessment List for Domestic Production Sites for information on substances handled under the PRTR Law. Please refer to the Safety Evaluation Table of Domestic Production Bases.
In addition, to enhance the overall level of chemical substance management, we conduct compliance verification by implementing chemical substance assessment that covers risk of adverse impact on employee health, risk of explosion or fire in relation to equipment and machinery, and environmental risk.

Efforts for Biodiversity Conservation Activities

The Mie Plant draws its water from the Miyagawa River system, which is renowned as one of Japan's clearest rivers, and discharges it into the Hinokijiri River. To minimize the impact on these two rivers and the surrounding ecosystem, we have divided the area around the plant into three locations, with three teams dedicated to environmental stewardship activities at each location.

Team 1 focuses on the retention basin within the plant premises, which is primarily fed by equipment cooling water and rainwater. To replicate the original aquatic environment of the Miyagawa River system, we conduct wildlife surveys and conservation activities. We also provide this area as a venue for environmental education, such as the "Millennium Forest" tree planting experience and biodiversity conservation activities, for local children.
Team 2 conducts water quality surveys in the midstream of the Hinokijiri River, as well as observing southern Japanese rice fish and dragonfly species.
Team 3 focuses on Ominato Beach, which is a nesting site for loggerhead sea turtles (Caretta caretta), a species designated as endangered II in Mie Prefecture. We conduct beach cleanup activities and remove invasive species to conserve native coastal vegetation and assess the condition of the shoreline.
In addition, we conduct environmental outreach classes led by our employees for fourth-grade students at Minato Elementary School every year, and 2024 marks the 11th time we have held this program.

Noise, vibration and odor

Noise

Noise management is implemented at the boundary of the premises of the plant (18 points) and autonomous measurement is conducted once a month.
In addition, measurements are conducted by an outside company twice a year at the boundaries of the factory premises (at four locations).

Vibration

Vibration management is implemented at the boundary of the premises of the plant (14 points) and autonomous measurement is conducted once a month.

Odor

Twice a year, external contractors conduct measurements at the factory site boundaries (4 locations).
Our response involves the installation of deodorizing vaporizers in building ducting.

Comments and information from local residents from the past and our response

Once a year, we hold a community meeting for local residents and environmental monitors near the factory to gather feedback and implement improvements.
We address information received from residents promptly and prioritize open communication.

Certification of new business partners

We have established guidelines covering human rights, compliance with all applicable laws and regulations, and our commitment to safety and environmental activities. These guidelines form the basis for our new supplier approval process, which includes interviews to ensure that we select suitable business partners.

Communication with business partners

As the secretariat for the Isuzu-kai, an organization of our suppliers, we hold meetings to explain our factory's safety and environmental policies and conduct study sessions to foster communication.
The Isuzu-kai also participates in local volunteer activities, such as the Seta River Tanabata Cleanup.

Safety and quality of our products and services

Using as a pillar the principle of “creating quality through the eyes of the customer,” at the Mie Plant we promote the continuous improvement of products and services by leveraging the quality management system ISO/TS 16949 (moved to ISO 9001 and IATF 16949 from June 2018) as our operational basis. We regularly confirm the effectiveness of this system through internal systems audits and external reviews that are conducted every six months.
In addition, by using “Quality Maintenance Activities” to ensure effective self-directed quality management throughout the entire production process, etc., we position quality as customer safety while working to ensure that all employees are conscious of the “eyes of the customer” being on them.
To provide our customers with environmentally friendly products, we are actively developing and producing tires with reduced rolling resistance, improved wear life, and superior retreadability. We are also increasing the production ratio of ultra-wide base tires, which contribute to reduced raw material and waste, as well as improved loading efficiency, to further minimize our environmental impact.
