Promotion System

In accordance with the ISO 9001 Quality Management System regulated by ISO (International Organization for Standardization), the pursuit of customer satisfaction is our fundamental policy and we guarantee the quality at every stage of planning, sales, design, manufacturing, installation and after-sales service.
We conduct quality management system initiatives based on top management reviews of the quality assurance system, which is linked with feedback from business operation management reviews that evaluate the achievements of each business operation and implement nonconformity corrective measures. In addition, as a company-wide management review, the CEO evaluates and makes judgments on the necessity for changes in the quality management system by reviewing the progress made in achieving our product quality goals with the aim to strive for continuous improvements.

Quality management system certification

We promote ISO 9001 certification, the international standard for quality management systems, at all major production sites in Japan and overseas. All three of our Japan production locations as well as 21 of our production locations outside of Japan have been ISO certified. 92% of our production facilities have obtained certification.

Major Initiatives

Response to quality issues

Should a major accident occur with our product, we carry out cross-company measures that incorporate other departments according to the need for detailed accident information by other operational departments and to register the corrective measures taken in a database. Reporting procedures are set out in the ISO Corrective Action and Preventive Measures Procedural Guide. We are thorough in preventing the recurrence of accidents and carrying out preventive measures, and regularly implement a management review through the CEO to verify the suitability of the quality management system.
