Product quality and safety

Ever since our inception, we have maintained a customer-first quality assurance system based on the "quality gleaning"(*)concept of Hitachi, Ltd. Furthermore, in September 1995, we obtained ISO 9001 certification to clarify our quality policies. As the core function of our group, we established the Corporate Quality Assurance Div, and the Quality Assurance Center at the Tsuchiura Works leads actual guidance, instruction and enlightenment activities for the quality assurance divisions of each group company. In the system, we collected comments from customers and salespersons as well as information on trouble at the Quality Assurance Center via each quality assurance division and we identify and take countermeasures to prevent recurrences for all the products through the pursuit of internal and other causes during product improvement meetings held in the presence of our president.

* Quality Assurance policy
Our top priority is product quality, and we supply creative products which are pleased with and trusted by our customers.
