Corporate Governance

Whistle-blowing System


We have established a helpline to receive inquiries and reports from employees aimed at curtailing and preventing activities contrary to the spirit of the NGK Group Guidelines for Corporate Behavior and to facilitate the quick resolution when issues occur. Each overseas Group company has its own helpline. Those seeking advice or reporting issues are promised protection under corporate regulations.


We have established a hotline as an internal control system for responding to fraud and legal infractions committed by senior management, including Competition Law and Anti-Corruption laws and regulations violations. The hotline is operated by outside lawyers, with issues handled by the Business Ethics Committee, composed mainly of outside directors, who report directly to the Board of Directors.
We will push forward with the establishment of the hotline at overseas Group companies in light of the circumstances in each country.

Compliance Card

With the aim of increasing awareness of the internal reporting system, we created carry-size compliance cards and distributed them to all employees at NGK and all domestic Group companies.
