In order to respond effectively to the increase in risk that has accompanied globalization, in July 2017 the Yokohama Rubber Group Competition Law Compliance Policy and Yokohama Rubber Group Anti-corruption Policy were approved by the Board of Directors and came into effect. By announcing these new policies both in Japan and overseas, and by formulating rules and guidelines that embody the policies in concrete form and familiarizing stakeholders with them, we aim to prevent violations of competition law and criminal offences involving bribery.
By integrating these policies with our Global Whistleblower System, adoption of which began in February 2018, and implementing them in our subsidiaries throughout the world, we believe we can raise the overall level of compliance in the Yokohama Rubber Group to an even higher level.

Our mission is to achieve corporate prosperity and contribute to society by not only satisfying customers but also winning their confidence and securing an appropriate level of profits. In order to achieve this, we must continually provide quality products that customers around the world will feel secure in buying and that will satisfy customers. In accordance with the Yokohama Rubber Action Guidelines, "We shall listen to the views of our customers, accurately ascertain their needs, and develop, design, manufacture, and sell products of genuine use to society."

Yokohama Rubber has established a Corporate Compliance Committee with the director in charge of the Corporate Administration Division as the Committee Chair and the Corporate Compliance Department as the implementation department. The Corporate Compliance Committee is held four times per year to continually implement various measures related to compliance at the Yokohama Rubber Group and report the state of these activities to the Board of Directors and Audit Committee members. The Corporate Philosophy and Action Guidelines of the Yokohama Rubber Group are made known and presented to Group companies, including overseas companies, to serve as the guidelines for the execution of duties by Directors and employees at each company. Every division in the Yokohama Rubber Group is assigned personnel who belong to the Corporate Compliance Department as well, to continue to share the progress of the activities in internal education and related information in the workplace. In our domestic and overseas group companies, we have appointed a compliance promotion manager to facilitate the development of the same level of activities in each company.

In the event of any quality problems or complaints in the market related to products provided to customers, we will respond promptly in an attempt to resolve such problems and implement recurrence prevention activities. As part of recurrence prevention measures, we regularly conduct quality audits to confirm the implementation status of corrective action and verify its effectiveness.

The Corporate Compliance Hotline refers to the system of accepting even anonymous whistle-blowing in accordance with the Whistleblower Protection Act. The telephone number and email address are stated on the Corporate Compliance Card that is distributed to all domestic Yokohama Rubber Group’s employees. There are two hotlines, an internal hotline and an external hotline. As the external hotline has been established at an external law firm, independence has been secured for this hotline. The General Counseling Room is the contact point which any members can utilize regarding any doubt or anxieties at work that are related to corporate compliance, and requires name registration as a general rule.In fiscal 2022, the total of the hotline and the General Consultation Room received 142 calls and consultations.
Yokohama Rubber has introduced a "Global Whistleblower System" at its overseas subsidiaries that allows the Yokohama Rubber Compliance Department to directly identify any violations of competition laws, bribery-related activities, and violations by local subsidiary executives through an external contact point. In February 2018, adoption of the new System began in China at the company responsible for overall supervision of our China-based operations and at our tire sales company in China.
By 2022, the introduction of the system in China, the Philippines, Thailand, Vietnam, and North America has been completed with the exception of some offices.
Beginning in 2023, we will begin studying the introduction of the system at our production facilities in Indonesia.
In Europe, our European headquarters signed a contract with a company that provides a whistleblowing system, and it implemented a joint whistleblowing system that it uses along with its eight subsidiaries. In addition to serving as a whistleblowing system for these nine companies, including the controlling company, the system also functions as a global whistleblowing system in which the Corporate Compliance Dept. directly receives reports from local employees depending on the content of the report.
This system has been in operation since January 2021.

In November 2022, a tire production company in Vietnam began operating an internal reporting system. In operating the system, we provided employees with introductory training. A new natural rubber processing company in Thailand also began operating the system in May.

Being able to appropriately monitor the state of compliance at overseas subsidiaries is an important issue. By making effective use of the periodic reporting system that is already being implemented, and of the global whistle-blowing system that we have begun to adopt, we are approaching the stage where we will be able to effectively monitor compliance issues at each overseas business location.
