Ensuring the Quality of Procured Products

To ensure effective business management, MIJI places great importance on the quality of our suppliers. We have implemented a quality assurance agreement with our key suppliers to uphold and enhance the standard of the products we procure. This agreement outlines our concept of quality assurance and specific requirements. Through collaboration between our procurement, quality, and engineering departments, we conduct regular audits on our suppliers based on the nature and significance of the products procured.These audits focus on various aspects such as the supplier’s quality control systems, manufacturing processes, quality testing, and adherence to industry standards and regulations.

In addition to audits, we also establish clear communication channels with our suppliers to ensure timely and accurate information exchange. This includes regular meetings to discuss any concerns, resolve issues, and provide feedback on product quality.
