Quality Assurance Initiatives

The MCC Group established new rules and policies at the time of the merger that formed the new MCC in April 2017 and has since been working to ensure awareness of the basic policy throughout the company. We are building appropriate quality management systems (based on ISO 9001,^*1 GMP,^*2 etc.) at our manufacturing sites and working to strengthen our quality assurance framework. Furthermore, we hold regular quality assurance meetings to share and effectively utilize information about quality within the Group as part of continuous efforts to improve quality. At the same time, we are focusing on quality assurance training.
In FY2024, we held a lecture with outside instructors for executives and management, including Group companies inside and outside of Japan. A cumulative total of 2,000 people have attended, and this is increasing awareness of quality.
