Quality assurance system at the corporate level

The Quality Assurance Headquarters has been established as a corporate quality assurance organization to strengthen the governance of quality throughout our group. The Quality Assurance Headquarters is headed by the executive in charge of quality assurance (Director) appointed by the Board of Directors. Members of the headquarters consist of the heads of quality-related business divisions and the presidents of affiliated companies, with Safety, Environment (HSSE) &Quality Assurance Department serving as its secretariat. The Quality Assurance Headquarters formulates policies for company-wide quality assurance activities and promotes initiatives to address such important issues as the maintenance, review and improvement of the quality assurance management system. Each business division operates its own PDCA cycle in accordance with these policies. As a general rule, the Quality Assurance Headquarters meets once a year to monitor progress in quality assurance activities and determine our basic policies for the next fiscal year. We also conduct regular quality audits to improve the activities of each division.
