Basic View
Based on our Credo, The Analects and the Abacus, we strive to fulfill social responsibilities through our business activities, thereby earning a greater degree of trust from our shareholders and investors, and all other stakeholders, including clients, employees, and local communities. We also aim to manage the company in an expeditious, efficient, transparent, and lawful manner to achieve sustainable growth and increase corporate value over the medium to long term.
To achieve this, we have established a structure that enables the Board of Directors and Audit & Supervisory Board Members to appropriately supervise and audit the performance of duties, based on separation of the management strategy decision-making function from the execution of duties function. Concurrently, our basic policy on corporate governance is for our directors, executive officers, audit & supervisory board members, and employees to practice compliance management based on high ethical standards.
Structure
Corporate Governance Structure of Shimizu Corporation

Overview of the Corporate Governance Structure
We have adopted the structure of a company with an Audit & Supervisory Board. We have chosen this system based on the belief that we have established a system to supervise and oversee management from an objective and neutral perspective. This was achieved by limiting the number of directors and introducing an executive officer system to clearly separate the management strategy decision-making and oversight functions from the business execution function, by taking steps to encourage energetic debate at the Board of Directors, and by electing outside directors, other non-executive directors, and outside Audit & Supervisory Board members who maintain a high degree of independence. The concrete structure and implementation status are detailed below.
- One-third or more of the Board of Directors elected are outside directors to strengthen management supervision function, and to promote more energetic debate by the Board of Directors.
- Outside directors and other non-executive directors and outside Audit & Supervisory Board members use their extensive experience and sophisticated insight based on their individual career histories to oversee and supervise management and provide necessary advice as appropriate.
- We established a structure mainly consisting of the head office administrative departments to provide timely information and other materials to assist outside directors and other non-executive directors in performing their management supervisory duties (including tours of offices, job sites, etc.).
- The relevant divisions provide guidance on the Company in general, description of its businesses, and other relevant information to new outside directors and outside Audit & Supervisory Board members.
- Audit & Supervisory Board members audit all duties performed by directors from a fair and impartial perspective.
- The Audit & Supervisory Board Members Office was established as the dedicated organization to support Audit & Supervisory Board members. This office secures the necessary support staff to enable more effective audits by Audit & Supervisory Board members.
- Audit & Supervisory Board members improve the effectiveness of management supervision by attending important meetings and obtaining sufficient information from officers and employees without delay.
- When a Board of Directors meeting is held, the Board of Directors administrative office and other divisions provide explanations in advance to the outside directors, non-executive directors, and Audit & Supervisory Board members.
- Outside directors and other non-executive directors regularly exchange opinions with the chairman and president. They also exchange opinions with outside Audit & Supervisory Board members.
- Regular Outside Officers Meetings are held for outside directors and outside Audit & Supervisory Board members, and regular Outside Directors and Audit & Supervisory Board Members Meetings are held for outside directors and all Audit & Supervisory Board members to facilitate the exchange of opinions.

Criteria for Assessing Independence of Outside Directors and Outside Audit & Supervisory Board Members
Support Structure for Outside Directors and Outside Audit & Supervisory Board Members
We have established a system to provide information to facilitate supervision of management by outside directors and other non-executive directors in performing their duties. The administration departments in the head office play the main role in providing this information in a timely manner. The Corporate Auditor’s Office was established as a dedicated organization to support Audit & Supervisory Board members. A sufficient number of staff members have been secured to assist outside Audit & Supervisory Board members. When a Board of Directors meeting is held, materials are distributed in advance and the Board of Directors administrative office and other divisions provide explanations in advance to the outside directors and the outside Audit & Supervisory Board members.
Directors, Audit & Supervisory Board Members, and Executive Officers
Officer Compensation
Policy on Determining Officer Compensation
The remuneration of each Director of the Company, which consists of a fixed-amount monthly salary that is the base salary and performance-based compensation that comprises bonuses and compensation exclusively for purchasing shares of the Company, is decided through deliberations of the Nomination and Compensation Committee, which is made up of a majority of Outside Directors and is chaired by a Non-executive Director, and which was established to evaluate the performance of Directors and decide on their remuneration in a fair and transparent manner, based on a resolution passed at the Board of Directors.
Non-Executive Directors including Outside Directors and Audit & Supervisory Board Members are paid only fixed-amount monthly salary for the purpose of enhancing their supervisory function of management.
We, at a Board of Directors’ Meeting held on February 24, 2021, resolved regulations for executives' remuneration that set forth the policy for determining the remuneration of each Director. Its outline is provided below.
Policy on Base Salary
Of the remuneration, etc. of Directors of the Company, the fixed-amount monthly salary that is the base salary is a maximum total of 90 million yen a month (including a maximum of 10 million yen for Outside Directors) pursuant to a resolution passed at the 117th Annual General Meeting of Shareholders held on June 27, 2019. As of the closing of the 117th Annual General Meeting of Shareholders, the number of Directors was 12 (including 3 Outside Directors).
Remuneration for Audit & Supervisory Board Members is a maximum total of 13 million yen a month pursuant to a resolution passed at the 89th Annual General Meeting of Shareholders held on June 27, 1991 and is decided through discussions at Audit & Supervisory Board. As of the closing of the 89th Annual General Meeting of Shareholders, the number of Audit & Supervisory Board Members was 4.
Policy on Performance-based Compensation
Of the remuneration, etc. of Directors of the Company, bonuses that are performance-based compensation is a maximum total of 500 million yen a year based on a resolution at the 118th Annual General Meeting of Shareholders held on June 26, 2020, and the Nomination and Compensation Committee deliberates on whether or not a bonus shall be paid and on what amount shall be paid.
The bonus amount is calculated according to the following method based on consolidated net income, the final results of the Group’s business activities for a business year. The “performance coefficient” used to calculate the bonus amount has been updated at the Board of Directors’ Meeting held on January 31, 2025 considering a proposal for deliberation presented by the Nomination and Compensation Committee to make it more clearly defined and provide management more incentives. The new coefficient is applied from the fiscal year starting on April 1, 2025.
(Method of calculating individual performance-based compensation [bonuses])
Consolidated performance*1 x Performance coefficient*2 x Positional index*3 x Individual evaluation coefficient*4 = Individual bonus*5
- *1. Consolidated net income for the current fiscal year (Net income attributable to shareholders of the Company)
- *2. The Nomination and Compensation Committee determines the earnings coefficient using ordinary income which represents the result of basic business development of the Company and an achievement rate against the targets set for the fiscal year of awards profitability of the construction business, a leading indicator of the business results for coming fiscal years, as main evaluation items. Other items are selected from non-financial KPIs from the Mid-Term Business Plan and added by the Nomination and Compensation Committee based on priority in terms of enhancing mid-to-long term corporate value and objectivity of evaluation. The Nomination and Compensation Committee then considers whether or not there is any material violation of laws and decides the earnings coefficient based on the evaluation value derived by weighted average of each item.
- *3. An index determined for each Director’s position
- *4. The Nomination and Compensation Committee determines individual evaluation indices based on the results of evaluations of the level of achievement of targets set for each director based on interviews with Executive Directors at the beginning and end of the fiscal year. (Evaluation indices range from 65% to 135%)
The multifaceted evaluations cover the short-term performance of each director in addition to their level of contribution to achieving the targets of the Mid-Term Business Plan, their efforts to strengthen the management base, their contributions to sustainability, and their performance as directorships.
Notably, only the non-executive directors of the Nomination and Compensation Committee Members make decisions regarding executive director evaluations. - *5. To encourage the further sharing of values with shareholders and increase corporate value over the medium to long term, an amount corresponding to 20% of the bonus as performance-based compensation, shall be deemed to be compensation for purchasing the Company’s shares, and each Director shall contribute this remuneration to the Executives’ Shareholding Association, which shall acquire the Company’s shares. The Company’s shares that are acquired in this way shall continue to be held for the duration of the Director’s tenure and for a fixed period of time after resignation.
Matters concerning delegation of decisions on compensation, etc.
We have established a Nomination & Compensation Committee which consists of a majority of outside directors and is chaired by a non-executive director, to ensure fair and transparent evaluation and compensation of directors and officers through deliberation by the committee based on the resolution of the Board of Directors.
The Nomination & Compensation Committee reviewed compensation for last fiscal year ended March 31, 2025 and discussed the base monthly salary and the amount to be paid as bonuses for each director according to the evaluation of the performance of each director, based on the Rules on Officer Compensation. The committee determined the compensation to be in line with policy determined by the Board of Directors.

FY2024
Securities Holdings
Policy on Securities Holdings
When there is a necessity from the viewpoint of business development, we acquire and retain shares of clients and business partners to strengthen and maintain relationships. Acquisition of major securities is determined by the Board of Directors, taking comprehensive consideration of benefits to the Company, acquisition cost, risk of share price changes and other factors. The Board of Directors examines the necessity of securities holdings for individual stocks each year, taking into consideration its economic rationality, including cost and risk of holding them, and business development benefits. Based on such examination, shares that have become dilutive in terms of significance to our operations, are disposed while confirming relationships with business partners.
Status of Reduction of Securities Holdings
To effectively use our capital, we established a following goal: “to reduce the ratio of the outstanding amount of securities holdings to consolidated net assets to less than 20% by the end of March 2027”, and announced it to the public on April 26, 2023. Since then, we have been seeking to reduce the volume of securities holdings. At the Board of Directors Meeting held on November 12, 2024, we have decided to move up the target date of the existing reduction goal by one year to the end of March 2026, so that we can accelerate the implementation of “management that is conscious of cost of capital and stock price”. We have also established a new goal of reducing the ratio of the outstanding amount of securities holdings to consolidated net assets to less than 10% by the end of March 2027”.
We sold shares of 31 listed companies during fiscal 2024 (including shares of which part of the holdings were sold). The proceeds were ¥58.6 billion. From fiscal 2018 to fiscal 2024, the total number of listed companies of which we sold its holdings was 91 (including shares of which part of the holdings were sold). The proceeds were ¥208.6 billion.
As a result, the number of listed companies we held shares in decreased from 187 as of the end of March 2018 to 123 as of the end of March 2025.
As of the end of March 2025, the proportion of securities holdings in consolidated net assets is 27.0%.

Criteria for exercising voting rights pertaining to securities holdings
We exercise voting rights on securities holdings after comprehensively examining the contents of proposals, referring to the Policy on securities holdings above, and judging whether to vote for or against each proposal from the perspective of whether the corporate value of the Company and business partners may increase.
Policy in case the cross-shareholder has expressed their intention to sell the shares
In case the cross-shareholder has expressed their intention to sell the Company’s shares, we will not act to prevent the sale by, for example, suggesting that we will reduce transactions with the company concerned.
Internal Control System Establishment
We have established a Basic Policy on Establishing a System of Internal Controls based on the Companies Act.

Code of Corporate Ethics and Conduct and Internal Corporate Structure
Code of Corporate Ethics and Conduct
We have adopted The Analects and the Abacus, which contains the teachings of Eiichi Shibusawa, as our corporate credo. We base our business activities on the conviction that our company’s business will always prosper if we pursue ethics and economic gain simultaneously, or in other words, if we do good work that delights the community and our customers and is grounded in a strong sense of ethics. In this era of strong demand for corporate social responsibility, we have established the Code of Corporate Ethics and Conduct to ensure that all officers and employees thoroughly understand The Analects and the Abacus and demonstrate it in their daily actions. We are committed to enforcing corporate ethics, including compliance with laws and regulations.
Establishment of Internal Corporate Structure
We provide education and training to ensure strict implementation and practical operation of the Code of Corporate Ethics and Conduct by officers and employees. We have also appointed an officer in charge of corporate ethics, established a Committee on Corporate Ethics, the Corporate Ethics Office, the Corporate Ethics Help-Line Office, and an internal whistleblowing system.
Proper Management of Personal Information
In addition to establishing the Privacy Policy, we have appointed a Corporate Personal Information Protection Administrator to promote appropriate measures for the proper management of personal information, including individual numbers (the “My Number” system).
Internal Whistleblowing System
The Shimizu Group has established an internal whistleblowing system allowing officers and employees of Shimizu, subsidiaries, and subcontractors to consult about or report various compliance issues that may arise within the Group, anonymously or otherwise. This encompasses actions by officers and employees of the Group that may violate the Code of Corporate Ethics and Conduct (such as harassment and other human rights violations, accounting fraud, bribery, and other corrupt practices).
Under this system, a Corporate Ethics Help-line Office, a Harassment Consultation Desk, and an External Consultation Desk staffed by outside attorneys have been established as Consultation and Reporting Desks (Compliance Hotlines). Reports submitted to these desks are thoroughly investigated, and appropriate measures are taken as needed. We ensure that whistleblowers are not subjected to any adverse treatment.
Stakeholders outside of the Shimizu Group may consult with us via the contact information on our website.
Internal Whistleblowing System Diagram

Initiatives Aimed at Strengthening Compliance
We implement various measures that will help cultivate an ethical mindset and contribute to strict compliance among Group officers and employees, so that they put the spirit of our corporate credo, The Analects and the Abacus, into practice in their actions.
Top management will lead by example in cultivating an ethical mindset and strict compliance.
- Corporate ethics training for executive management (including management of Group companies)
- Compliance e-learning training (including Compliance with the Anti- monopoly Act)
Make sure that everyone understands the code of conduct on bidding for construction projects (mainly for Shimizu and construction-related subsidiaries)
We conduct training and interviews for officers and employees to ensure thorough awareness of the code of conduct as well as interviews by outside attorneys and other experts as necessary on a case-by-case basis.
