Quality Management Based on ISO 9001
Since obtaining ISO 9001* certification at the Hachioji and Tsuchiura plants in 1994, we have established the Tokyo Seimitsu Quality Management System (QMS) and have been promoting quality improvement activities through the PDCA cycle based on quality policy and quality targets. In fiscal 2023, during an certification inspection conducted by a certification body, an inspection was carried out for certification renewal, including for the Hanno Plant which was completed in July 2023, confirming compliance with the requirements of ISO 9001: 2015 and that management effectiveness has been maintained. Furthermore, the charge/discharge testing business which we transferred in October 2023, maintains its certification status since a special inspection was conducted for the business by the same certification body.
* ISO 9001
An international standard concerning systems and mechanisms of management to achieve goals in response to the needs of an organization’s customers and markets, through quality assurance for products and services.
PDCA Cycle Based on Our Quality Policy and Quality Targets

The Quality Management Committee consists of 10 members: One Quality Officer, three officers in charge of business, three quality control managers, and three Sustainability Department members. The Quality Management Committee meets twice a year to review the performance, effectiveness, and appropriateness of the Quality Management System. The Quality Officer reports to the Board of Directors and receives instructions and supervision. In fiscal 2023, there were no quality management issues that required corrective actions to be taken.
Quality Control Structure
Internal Quality Audits
The internal audit team conducts Internal Quality Audits twice a year at the Company. Certified auditors conduct audits in accordance with the quality manual* under the direction of the Quality Control Managers of the Semiconductor Company and Metrology Company, who report the audit results and the effectiveness of the Quality Management System to the Quality Management Committee. During the Internal Quality Audits performed in fiscal 2023, the auditors did not indicate that corrective actions were needed to be taken.

Supplier Quality Audits
Suppliers who supply many of the parts and components required for our products cooperate in the quality audits that we conduct using our ISO 9001-compliant checklists. In fiscal 2023, supplier quality audits were conducted at 11 companies (cumulative total of 219 companies). There were no follow-up audits conducted as there were no cases of non-compliance with our quality control standards and/or quality requirements.
