THK Group Structures

The THK Group has established the following structures related to human rights.

  • THK's Compliance Structure
    In Japan, we have established a Compliance Committee chaired by the CEO, and compliance subcommittees consisting of representatives from all offices, departments, and Group companies report to this committee.
    In addition, each Group company around the world has designated a person in charge of human rights and coordinates with the Compliance Committee and compliance subcommittees to ensure smooth communication.
  • THK Group Helpline
    The THK Group provides a helpline for employees to consult about or report matters concerning wrongful acts, legal violations, and unethical behavior, including issues related to human rights. A separate, dedicated point of contact is also available for incidents of harassment.

Human Rights Efforts


Using a variety of methods, including a web conference system, in-person training conducted by internal or external instructors, e-learning materials, the company intranet, and internal information boards, the THK Group regularly disseminates valuable information and conducts training about human rights topics.

In 2022, we conducted the following human rights training.

  • Held a seminar on human rights
    In April 2022, a voluntary internal seminar on human rights was held for compliance subcommittee members and human rights personnel in Japan.
    This seminar was an opportunity for participants to reflect on human rights, as it focused on defining human rights and explaining what related activities society expects from corporations, all while providing real-life examples.

  • Shared materials on human rights within the THK Group
    Training materials about human rights, primarily those that were used for the seminar conducted in Japan, were translated into English and shared throughout the global THK Group.

  • Displayed informational posters about human rights
    Informational posters on human rights were created and displayed at THK's business locations throughout Japan.

  • Conducted the Compliance Subcommittee Seminar
    An annual Compliance Subcommittee Seminar is held for compliance subcommittee members. The seminar this year was conducted virtually through a web conference system, and the theme was how to have effective internal communication in order to prevent or correct compliance violations.
    Participants learned about the importance of mutual respect, which is a fundamental part of respecting human rights.

  • Trained employees with "Compliance Tips"
    "Compliance Tips" is an internal publication issued quarterly for employees in Japan in order to improve employee awareness and knowledge of compliance.
    This year, this publication was used to provide internal training on bribery from an anti-corruption perspective.
    "Compliance Tips" is published to the company intranet and posted on each floor's information board. Compliance subcommittee members also distribute PDF copies to employees.

    Training and Activities to Raise Awareness

Supply Chain Transparency

In order to achieve supply chain transparency, the THK Group has distributed its CSR Procurement Guidelines to suppliers and conducts surveys or interviews as appropriate to confirm compliance with those guidelines.

CSR Procurement Guidelines

In 2022, THK conducted a survey of its Japanese and overseas Group companies and its direct domestic suppliers in order to examine each company's human rights efforts.

  • Survey of THK Group Companies
    Scope: 24 THK Group companies (Response rate: 100%)

    The THK Group works to respect human rights based on the THK Group Human Rights Policy and the Fundamentals for the THK Group Employees.
    In addition, because each Group company implements its own activities, a survey was conducted at both domestic and global locations in order to confirm the current status of these efforts.
    The survey found that there was no problem with regard to the fundamentals of prohibiting discrimination, forced labor, and other human rights infringements related to employment, but there were varying levels of involvement with human rights issues involving the supply chain, such as conflict minerals and anti-corruption. Moving forward, the THK Group will share information and work on human rights efforts together as a cohesive whole.

  • Survey of Direct Suppliers in Japan
    Scope: 501 direct suppliers (Response rate: 76%)

    THK asks its suppliers to work on human rights efforts in accordance with the THK Group Human Rights Policy and the CSR Procurement Guidelines.
    In addition, a survey of select suppliers was conducted in order to identify the human rights challenges in THK's supply chain that require special focus.
    The results indicate that all of the suppliers have a high level of awareness with regard to human rights. However, it became clear that there were different levels of activity among suppliers, so THK will put more effort into informational campaigns and strive for improvement.
  • THK Group Challenges

    Among its various human rights initiatives, the THK Group recognizes the following matters as especially critical challenges.

    • Eliminating Discrimination
      The THK Group respects the basic human rights, individuality, and diversity of individuals. Furthermore, we do not discriminate, harass, or otherwise treat individuals inhumanely based on race, gender, language, religion, nationality, sexual orientation, gender identity, or disability.

    • Improving the Labor Environment
      The THK Group respects labor agreements and does not engage in any forced or child labor. By maintaining a dialogue with workers and striving to create a vibrant corporate culture in which all people respect each other for their diverse individual characteristics, we create a working environment where employees can work safely and with peace of mind, in a manner that is healthy both mentally and physically.
      In order to engage with this issue, we regularly conduct internal surveys to identify issues and consider improvements.

    • Ethical Material Procurement
      The THK Group aims for ethical procurement in its purchasing of components and materials used in its manufacturing processes. We strive to ensure that our procured goods do not contribute to human rights violations, and if we become aware of any such involvement, we will respond appropriately.

    Education Efforts in the Supply Chain

    The THK Group strives to ensure our suppliers are made aware of our human rights activities, and we request that our suppliers make similar human rights efforts.
