Our Philosophy

We strive to maintain solid corporate governance in order to maximize our corporate value by sustaining growth through appropriate cooperation with our shareholders and other stakeholders.

In conjunction with our establishment of an Audit and Supervisory Committee, THK instituted a non-mandatory Nomination Advisory Committee and a Remuneration Advisory Committee, each with an outside director majority, to ensure further transparency and fairness in management personnel and remuneration.
In addition, through our executive officer system, we have strengthened the auditing functions of the Board of Directors in addition to bringing greater speed and efficiency to management-related decision-making and the management of corporate affairs.

Board of Directors

THK’s Board of Directors comprises a total of eight directors—including two outside directors—who are not members of the Audit and Supervisory Committee in addition to three outside directors who are Audit and Supervisory Committee members. The Board of Directors makes decisions on important matters of general management and carries out the oversight of directors and executive officers in the execution of their duties.
THK's five outside directors, whose independence meets the evaluation criteria stipulated by the Tokyo Stock Exchange and THK, possess specialized professional knowledge and qualifications related to corporate accounting, management, and other relevant skills. Accounting for over a third of our directors overall, they have further enhanced management neutrality, independence, and validity while improving the board's management oversight function.

Director Composition

Director Composition

Audit and Supervisory Committee

Comprising three outside directors who are Audit and Supervisory Committee members, the Audit and Supervisory Committee utilizes the internal control system to audit and supervise directors and executive officers with regard to the current status of the execution of their duties. The committee enhances the effectiveness of audits through its partnerships with an accounting auditor, the Internal Audit Department, and the Risk Management Department, which maintains and implements internal controls.
Additionally, an Audit and Supervisory Committee Secretariat has been established to assist in the smooth functioning of the committee by supporting its members and their work. The secretariat follows the instructions of the Audit and Supervisory Committee, coordinates with each department, and conveys instructions to the Internal Audit Department and the Risk Management Department.

Nomination Advisory Committee and Remuneration Advisory Committee

The Nomination Advisory Committee and Remuneration Advisory Committee are each composed of three directors, two of which are outside directors. This is in accordance with the rules for both committees, which stipulate that outside directors must make up more than half of the members and that each must also be chaired by an outside director.
As advisory bodies to the Board of Directors, both committees review and deliberate on director candidates and remuneration proposals, and they propose the content and outcomes of those deliberations to the Board of Directors. The Board of Directors conducts its own deliberations based on their proposals before deciding on a resolution.

Executive Officer System

By introducing the executive officer system, we have endeavored to accelerate decision-making and operational execution in addition to improving the management oversight function of the Board of Directors and clarifying roles and responsibilities relating to the management of corporate affairs.
THK has established both a Board of Executive Officers, attended by directors and executive officers, and a Global Management Strategy Meeting, attended by members of the Board of Executive Officers in addition to those in charge of each division, department, and affiliate company. These serve as forums for directors, executive officers, and other members of management to collaborate to share information across the Group and improve our corporate governance.
To clarify the roles and responsibilities of executive officers relating to the management of corporate affairs, an executive officer’s term in office is deemed to be one year.

We conduct an annual survey on the capabilities of the Board of Directors in order to ensure its effectiveness and improve its performance.
In 2025, as in 2024, this survey and interviews with each director were conducted through a third-party organization.

Purpose of the 2025 Third-Party Evaluation

At the time of the 2024 evaluation of the effectiveness of the Board of Directors (the previous year’s evaluation), THK determined that developing our corporate governance to promote management that emphasized profitability and capital efficiency required specialized, objective evaluation of the effectiveness of activities undertaken to enhance our corporate value. As a result, a third-party organization was enlisted to perform such an evaluation of the effectiveness of the Board of Directors.

2025 Results and Policy Responses
Overview

In order to ensure business continuity and enhance medium- to long-term corporate value, THK has established and maintains a succession plan for the position of Chief Executive Officer (CEO). This succession plan is intended to support our continual growth as a company focused on creation and development while reflecting THK’s philosophy and values, and it is promoted within the context of a governance structure that prioritizes transparency and accountability.

■ Goals of succession
・Ensure business continuity and continual growth of corporate value
・Maintain transparency and accountability toward stakeholders

Process

THK’s succession plan uses the following process to develop the next-generation of leaders.
1. Establishment of requirements
The capabilities, character, and values required of a CEO are clearly defined. These include leadership, embodiment of our corporate philosophy, management of human capital, diversity awareness, and global perspective.
2. Creation of a candidate pool
A list of candidates is made and program participants are selected.
3. Development planning
A plan is implemented for ensuring that candidates reach their full potential.
4. Evaluation and selection
Candidate evaluations involve the following.
■ Comprehensive quantitative and qualitative evaluations
■ Objectivity of evaluations ensured by the Nomination Advisory Committee and interviews with outside directors

Other: Emergency response (BCP response)

To minimize succession risks, THK has a clearly defined short-term structure to account for a CEO’s absence and maintains an emergency response framework to prevent gaps in executive leadership.

Future developments

THK will continue to develop next-generation leaders who embody our corporate philosophy and are capable of flexibly responding to a business environment defined by drastic change. We will refine our governance and the way we manage human capital to make our management structure an ever stronger driver of sustainable growth.

Basic Policy

It is our basic policy that the remuneration structure for directors (excluding directors who are Audit and Supervisory Committee members and outside directors) will be tied to shareholder interests in order to ensure that such compensation functions effectively as a continued incentive to improve corporate value, and decisions on remuneration for individual directors are based on an appropriate standard in consideration of their duties.

Base Salaries

The annual sum of all director base salaries is held at or below ¥1.2 billion, no more than ¥120 million of which may go to outside directors. These base salaries are determined by the Board of Directors using a ranking system they have created to account for the scope of each individual’s roles and responsibilities. These determinations reflect reviews and reporting from the Remuneration Advisory Committee and use the compensation structures of other manufacturing companies on the Prime Market with comparable operating incomes as a baseline.
The annual base salaries of outside directors must remain under ¥120 million, and the amount is determined based on compensation standards for companies of a similar size, industry, and type of business.

Performance-Based Incentives

Performance-based compensation is determined by business performance and individual KPI evaluations. Compensation tied to business performance corresponds to THK’s ROE, starting at zero and scaling linearly with benchmark ROE values. Personal KPI evaluations take both quantitative and qualitative metrics into account. Performance-based incentives are not provided to outside directors.

Restricted Stocks

As an incentive to continuously improve THK’s corporate value, restricted stocks are provided to directors (excluding directors who are Audit and Supervisory Committee members and outside directors). In order to align the interests of directors with those of shareholders, these stocks may not be transferred except under specific circumstances, and when such conditions are met, they will be allocated as common stocks, which are subject to restrictions such as being allotted without contribution.
Furthermore, based on a resolution by THK’s Board of Directors, the annual sum when combined with the base salary shall not exceed ¥1.2 billion (no more than ¥120 million of which may go to outside directors), and no more than 270,000 common shares may be allocated to directors (excluding directors who are Audit and Supervisory Committee members and outside directors).

Compensation Structure Policy

The Board of Directors determines the proportion of each type of compensation based on each director's role and rank, taking into account reviews and reporting from the Remuneration Advisory Committee, more than half of whose members, including the chairperson, are outside directors.
