Corporate Governance

Whistleblowing 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 Code of Conduct and to facilitate the quick resolution when issues occur. Each Group company outside Japan has its own helpline.

We have established a hotline as a whistleblowing system for responding to fraud and legal infractions committed by senior management of NGK, and competition law and anti-corruption law-related 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 have been pushing forward with the establishment of the hotline at Group companies outside Japan in light of the circumstances in each country. We have, however, established contact points at all Group companies outside Japan for reporting competition law and anti-corruption law-related violations.

Whistleblowing System

A whistleblowing system is in place, which everyone who works for NGK and its Group companies (including executives, employees, employees temporarily assigned to outside companies, advisors, contract employees, temporary employees hired on a worker dispatch agreement, and subcontractor local employees) can utilize.
As a rule, actual names are used for consultations and reports, but outside contact points can be utilized for anonymous consultations. Those seeking advice or reporting issues are promised protection under corporate rules.

Organization of Whistleblowing System

Organization of the Whistleblower System. Via internal and external contact points, reports regarding violations of laws and regulations received from individuals seeking consultations reach the Board of Directors without being made known to their superiors.

Compliance Card

For thorough awareness of the whistleblowing system, we created a carry-size Compliance Card and distributed it to all employees at NGK and all Group companies in Japan.
