NSK’s Approach

The NSK Group has positioned compliance as one of its core values. For NSK, compliance goes beyond adherence to laws and regulations. It also entails acting in accordance with internal rules, social norms and the Corporate Philosophy in a sincere and fair manner. Moreover, compliance means earning the trust of society and contributing to the development of the economy and society in Japan and around the world.

Compliance Promotion System

The Legal and Compliance HQ formulates policies to strengthen the compliance structure of the NSK Group, implements various measure based on these policies, and continuously monitors the implementation status. Activities of the Legal and Compliance HQ are reported to the Core Values Committee on a regular basis. Through the discussion of policies for promoting and strengthening compliance, which is one of our core values, and sharing of relevant risks, the Core Value Committee makes recommendations and monitors progress toward resolving company-wide compliance issues.

The NSK Group has appointed persons responsible for compliance at each department, site, and NSK Group company in Japan as well as each headquarters outside Japan to serve as key contact points who regularly report on compliance and conduct risk management.

For more information on the Core Values Committee, please visit NSK Corporate Governance Structure.

Global Legal and Compliance Meetings

In order to strengthen the global compliance system, global legal and compliance meetings are held twice a year. At these meetings, members responsible for compliance from the Americas, Europe, China, ASEAN, India, and South Korea gather to report on and discuss compliance activities in their respective regions and countries. This includes compliance training implementation methods and compliance hotline operation. They also share information on relevant laws and regulations in each country, helping one another to identify ways to improve future performance.

Creating Internal Regulations, Training and Awareness Raising Activities

Distribution of Compliance Guidebook

NSK distributed the NSK Compliance Guidebook, which explains the 16 items of the NSK Code of Conduct Concerning Compliance in the NSK Code of Corporate Ethics, to officers and employees of the NSK Group to raise awareness about compliance. We have prepared additional localized versions of the guidebook when needed, based on relevant national laws. Employees who receive the Guidebook pledge to abide by its content.

NSK Compliance Guidebook

Preventing Violations of the Competition Law

The NSK Group has established Rules for Compliance with Competition Law. We prohibit officers and employees from exchanging information or making arrangements with competitors regarding product prices or customers, or from making efforts to restrict sales price setting by retail stores. Moreover, contact with competitors is prohibited in principle. Whenever officers or employees need to participate in a business meeting where there is a chance for interaction with competitors, they must submit an application in advance followed by a report afterwards.
We also conduct training worldwide, focusing on sales departments annually. The training covers competition law and other compliance-related themes. The training includes the review of past cases of cartel behavior, in order to keep the applicable lessons fresh in employee minds.


The NSK Group’s Anti-Bribery Standards prohibit officers and employees not only from engaging in bribery, but also giving or receiving entertainment or gifts that deviate from publicly accepted norms. In principle, the provision of entertainment or gifts to any officer or employee of a public institution is prohibited.
Based on the Anti-Bribery Standards, localized internal regulations have been established for Group companies worldwide, based on relevant anti-bribery laws. The NSK Group regularly conducts training and e-learning programs to prevent bribery.

Preventing Insider Trading

The Internal Regulation for Preventing Insider Trading applies to all officers and employees of the NSK Group. This regulation prohibits officers and employees from buying or selling company stock while in possession of insider knowledge of related undisclosed information. Personnel in this situation are also not allowed to encourage others including family members to buy or sell company stock. It also prohibits NSK Group officers and employees from purchasing NSK shares on the stock market. When selling NSK shares, they must apply for permission in advance using a special system. We are working to ensure thorough awareness of insider training across the Group. We provide e-learning modules and other training, posters, and internal communication materials such as the Compliance Newsletter.

Security Export Control

The NSK Group has strengthened its system for controls for preventing products and technology from being exported for the aims of the development, manufacture, and use of weapons, based on Japan’s Foreign Exchange and Foreign Trade Act. A basic policy and system of controls related to security export have been set forth in the Standards on Security Export Control, and we are working to maintain and improve the reliability of the NSK Group’s export-related operations and to reduce the risk of legal violations.

Protecting Personal Information

The NSK Group maintains a basic policy concerning the acquisition, management and protection of personal information. Internal control systems have been set up for the protection of personal information based on the actual business situation. These enable the Group to collect, use, and provide personal information appropriately in accordance with its prescribed rules. We continually strive to prevent unauthorized access to personal information, as well as its leakage, loss, destruction, or falsification. This includes carefully supervising Group employees who process data containing personal information and any external provider contracted to do so.

No Association with Organized Crime

The NSK Group is fulfilling its corporate social responsibilities with a basic policy for completely blocking any association with organized crime, including transactional relationships. Furthermore, this policy is spelled out clearly in the NSK Code of Corporate Ethics and awareness of it is continually promoted to ensure a systematic response across the Group. We have also strengthened cooperation with the police and other external organizations. In Japan, the Group adds special clauses to its contracts with business partners to enable cancellation if the business partner is later found to be connected with organized crime.

Tax Compliance

As the globalization of business advances, the NSK Group believes that the proper payment of taxes in the countries and regions where it operates is one of the most fundamental and important social responsibilities that it should undertake. In March 2018, we established the NSK Group Tax Policy. We are striving to ensure appropriate tax treatment, including refraining from forming organizations that are inconsistent with business purposes and actual conditions for the purpose of tax avoidance.

Initiatives to Reduce Compliance Risks in Each Division

With the aim of reducing compliance risks in each division, the NSK Group conducts compliance training by department. In sales departments, we have been conducting training on the themes of competition laws and keeping the cartel incident fresh in our memories since FY2012. In FY2022, training was held on the themes of the Antimonopoly Act and mismanagement of expenses. Looking back on the response to the cartel incident, we continued to implement the storytelling activities that began in FY2020 to pass on the facts and lessons learned. Employees from all sales divisions in Japan attended the course. In production departments, training is conducted on the theme of preventing quality fraud such as data falsification. In FY2022, we conducted operator-level employee training at three production sites in Japan, and all employees attended the course. In engineering departments, we conducted training on the themes of fostering engineering ethics and preventing quality fraud such as data falsification. In FY2022, employees from all technical departments in Japan attended the course. The NSK Group also disseminates information via internal communication materials such as the Compliance Newsletter, otherwise known as the “Compliance Kawaraban,” with the aim of further raising compliance awareness among officers and employees.

NSK Corporate Philosophy Day

To revisit the lessons learned from past incidents, reconfirm the resolve of all NSK Group employees that no anticompetitive incident will ever occur again, and ensure that all employees review the Corporate Philosophy and make it their own code of conduct, July 26, the date of our on-site inspection by the Japan Fair Trade Commission, has been designated as “NSK Corporate Philosophy Day.”

In FY2022, employees at our domestic and overseas bases watched videos titled “Message from the President,” “Understanding Our Corporate Philosophy,” and “A Look Back at the Cartel Incident.” Thereafter, in Japan, a presentation in animated form was given on the importance of each individual communicating and listening to their thoughts and feelings in order to act in accordance with the Corporate Philosophy. Taking advantage of NSK Corporate Philosophy Day, group discussions were held at each workplace on the themes of “things that bother me” and “things I want to change,” as an initiative to share their own thoughts. Overseas, after a message from the management of local bases, each site held its own events that included lectures by outside experts and discussions on compliance.

Employee Engagement Surveys (Compliance Awareness Surveys)

An employee engagement survey is conducted with the Human Resources Department. The objective is to assess the level of compliance awareness and the condition of work environments, in terms of motivation and opportunities for growth for each employee. We are working to address issues identified based on employee engagement surveys. These activities include raising compliance awareness in the manufacturing division, while further improving the compliance hotline’s reliability.

Auditing and Inspection

Since FY2013, the Compliance Enhancement Office in NSK’s Legal Department has been conducting annual audits to assess the extent of compliance with competition law. We also use self-inspections to check for risks relating to specific compliance topics.

Compliance Hotline (Whistleblowing System)

The NSK Group has made explicit in its internal rules that employees who learn of acts that violate or might violate the NSK Code of Corporate Ethics or compliance are to contact the compliance hotline made available in their regions and countries. The Group makes sure that employees are well informed about these hotlines. In some countries and regions, the hotline is available to suppliers, as well.
In Japan, we established hotline operational rules to ensure that the functioning of our system is in full compliance with Japan’s Whistleblower Protection Act. We have also set up internal and external hotlines, which accept reports 24 hours a day. The system allows hotline users to remain anonymous, and rules are established to ensure they are protected from disadvantageous repercussions. Reported incidents are investigated by the Legal and Compliance Division Headquarters in Japan and by the local legal department outside Japan with the help of relevant departments as needed. If a compliance violation becomes apparent, corrective actions and recurrence prevention measures are quickly taken where needed.
We are distributing business card-sized cards containing the hotline contact information to make the system well known to employees. In addition, we disclose the number of reports and the status of measures taken in response to reported incidents via internal corporate communication tools, helping to form a corporate culture that ensures employees can use the system with peace of mind. In FY2022, 143 reports were received globally.
