Human Rights Management
Our position
The Yokohama Rubber Group places great importance on respecting human rights throughout its supply chain, in order to respect the human rights of all individuals involved in its business. As our business expands globally, the potential to impact human rights violations increases. We believe it is essential to fulfill our responsibilities, considering the scope of our influence.
The "Yokohama Rubber Group Action Guidelines" clearly states that we respect human rights, both internally and externally, and clarifies the code of conduct for our employees.
Furthermore, based on the UN Guiding Principles on Business and Human Rights※, we have formulated the "Yokohama Rubber Group Human Rights Policy", aiming to respect the human rights of all individuals involved in our business activities.
Human rights are fundamental rights granted to all individuals. As a company trusted by society at large, we will practice human rights initiatives throughout the Group to contribute to the realization of a sustainable society.
- The UN Guiding Principles on Business and Human Rights were endorsed by the UN Human Rights Council in 2011 as a framework for respecting human rights that applies to all states and all businesses. The Guiding Principles emphasize "the State's duty to protect human rights" alongside "the corporate responsibility to respect human rights" as key pillars.

The Yokohama Rubber Group Human Rights Policy
The Yokohama Rubber Group Human Rights Policy (established in April 2022)The Yokohama Rubber Group Human Rights Policy serves as the basis for all of the Group's business activities as its top human rights policy, based on the Corporate Philosophy and the Yokohama Rubber Group Action Guidelines.
Our Human Rights Policy applies to all officers and employees of the Yokohama Rubber Group (directors, auditors, executive officers, other persons associated with business execution in relation to management, and those in employment contracts with Yokohama Rubber Group companies, employees accepted on seconded and temporary employees). To ensure that our commitments to human rights can be realized in our business activities, we expect that all of our business partners including suppliers and distributors will also understand and support this policy.
CSR Procurement Guidelines
CSR Procurement GuidelinesThe "CSR Procurement Guidelines" have been revised to reflect changes in social conditions and the expansion of our activities. In line with the formulation of the Yokohama Rubber Group Human Rights Policy, the October 2022 revision reflected the contents of the Human Rights Policy, which strongly requests our business partners to protect human rights in the supply chain and prohibit discrimination and harassment. Furthermore, in May 2025, we implemented revisions to expand the descriptions related to human rights.
Sustainable Natural Rubber Procurement Policy
Sustainable Natural Rubber Procurement PolicyThis policy includes specific guidelines regarding respect for human rights, such as "Respect for Human Rights," "Fair and Equal Treatment," "Prohibition of Harassment," "Prohibition of Child Labor," "Prohibition of Forced Labor," and "Ensuring Appropriate Working Conditions," and we are implementing initiatives to uphold these guidelines.
Promotion system and governance
The Group reports and discusses human rights issues at the Compliance Committee, held four times a year (Chairman: Director in charge of Compliance), and the CSR Meeting, held twice a year (chaired by the Representative Director, Chairman and CEO). These discussions are also regularly reported to the Board of Directors and the Audit Committee. For significant risks and their response policies that could impact management, the Officer in charge of Risk Management discusses and deliberates them at the Management Meeting and Board of Directors. Based on the approved policies, relevant departments collaborate to implement countermeasures.
The "Yokohama Rubber Group Human Rights Policy" is disseminated to all group companies, including those overseas, through training and other initiatives, and serves as the top-level policy on human rights for directors and employees of each company. This policy forms the foundation for all business activities of the Yokohama Rubber Group.
Message from a manager
Under the slogan of "Caring for the Future" in its sustainability management, the Yokohama Rubber Group will implement efforts for the respect of human rights as the basis of its business activities based on our "Corporate Philosophy.", "Yokohama Rubber Group Action Guidelines" and "Yokohama Rubber Group Human Rights Policy" in order to contribute to the realization of a sustainable society as a company that is widely trusted by society.
As one specific initiative, we participate in the Global Platform for Sustainable Natural Rubber (GPSNR), which was launched primarily by the Tire Industry Project (TIP) of the World Business Council for Sustainable Development (WBCSD). Regarding the procurement of natural rubber, which involves various risks such as human rights and labor issues, we aim to achieve sustainable procurement by establishing traceability and providing support that addresses the problems faced by local communities and plantations.
By December 2024, we had visited and conducted interviews at 861 farms in the Suratthani province in Thailand, where our natural rubber processing factory is located.
Going forward, we plan to work with third-party organizations to re-examine human rights issues and consider corresponding countermeasures.
For procurement items other than natural rubber, we will more strongly request our suppliers to protect human rights and prohibit discrimination and harassment in the supply chain based on the CSR Procurement Guidelines.
The Yokohama Rubber Group will share these principles throughout its relevant supply chains, respect the human rights of all individuals involved in its business activities, and strive for continuous improvement.

Priority measures
Human Rights Due Diligence
Identification of Key Human Rights Themes / Issues
- We conducted a research investigation, including on-site interviews with rightsholders, to identify specific human rights issues and rightsholders (individuals potentially impacted by our business activities). This research aimed to confirm who and which human rights are actually being affected or not affected.
<Key Human Rights Themes / Issues>
- Working conditions of foreign workers in Japan
- Working conditions of workers and environmental impact on nearby residents at rubber raw material suppliers (Thailand, Indonesia, etc.)
- Workplace environment of workers at contracted companies (manufacturing, logistics, sales, disposal)
Initiatives for 2024
1. Implementation of Impact Assessments
In 2024, we conducted an impact assessment on theme 2: "Working conditions of workers and environmental impact on nearby residents at rubber raw material suppliers (Thailand, Indonesia, etc.)."
<Impact Assessment in Suratthani Province, Southern Thailand>
Suratthani Province is a major natural rubber producing region and the location of our Group's natural rubber processing plant, Y.T. RUBBER CO., LTD. (YT Rubber). Since 2019, we have been conducting "Farm Surveys" to voluntarily check for problems such as illegal deforestation and human rights violations at natural rubber plantations in the region, and we have conducted approximately 750 surveys by May 2024.
In this impact assessment, a third-party organization provided its perspective to evaluate our past activities and analyze/assess potential human rights infringement risks.
<Target Groups and Implementation Methods for Hearings>
It is worth noting that representatives from our Group did not attend the hearings, and only the third-party organization conducted them. This was done to encourage rights holders/stakeholders to express their opinions candidly.
Hearings with Farm Owners
Hearings with Farm Workers
Hearings with Raw Rubber Brokers
Hearings with Drivers
Hearings with Village Chiefs
Hearings with Hospital Directors
<Results of the Impact Assessment and Response Policy>
Based on these results, in the self-inspection following the impact assessment, we are focusing on investigating farms employing Myanmar workers and striving to understand and improve their working conditions. In addition, we are distributing Myanmar-language labor contract templates, created by YTRC under the advice of the Thai Department of Labor, to farm owners and encouraging them to conclude labor contracts.

Moving forward, we will continue to expand and accelerate our human rights due diligence initiatives and other efforts in Yokohama Rubber Group business locations and supply chains, in accordance with the UN Guiding Principles on Business and Human Rights (UNGP).
Human Rights Complaint Handling System
1. Complaint Handling System for Employees of the Yokohama Rubber Group in Japan
Within Japan, the Compliance Promotion Office has established two dedicated channels: the "Compliance Hotline" and the "General Consultation Room," where employees can directly report concerns or seek advice via phone or email. These channels prioritize the privacy of the reporter/consultant, ensuring confidentiality regarding the fact of reporting/consultation and its content. Furthermore, unless for false or fraudulent purposes, reporters/consultants are protected from any unfavorable treatment due to their reporting/consultation.
Furthermore, we have designated "Compliance Promotion Office Staff" in all departments and "Compliance Promotion Leaders" in affiliated companies to establish a network that connects employees' complaints and consultations to the Compliance Promotion Office.
For human rights complaints, the Compliance Promotion Office collaborates with internal departments such as Human Resources and CSR to work towards a resolution.
<Scope of Application for the Grievance Handling System>
<Methods for Communicating the Grievance Handling System>
Additionally, "Compliance Cards" are distributed to all eligible individuals, outlining the reporting process and other relevant information, to ensure awareness of the available channels for reporting concerns.
<Resolution Process for Grievances>
- The Compliance Promotion Office will verify the facts of the consultation received from the consultant.
- The Compliance Promotion Office will consult with relevant internal departments to determine and implement necessary actions.
- If the reporter has disclosed their identity, they will be informed directly of the outcome. If the report was anonymous, appropriate measures will be taken to raise awareness within the company as needed.
