◆Tamura Group Quality Policy
Regarding quality, one of the essential factors for the future growth of the company, based on the Group's renewed conviction that it needs to foster a corporate culture where the quality-first philosophy is a matter of course, it revised its quality policy in January 2021. Under the new quality policy, the Group set “Creating Correct, Quality Products” as its compass in accordance with the “Biltrite Tamura” slogan, which was set forth during the start-up phase and has been handed down to the medium-term management plans. Furthermore, the Group translated what this quality policy means into specific action guidelines (Eight Articles of Manufacturing for production and 10 Rules of Design for development) with the aim of making Tamura's quality culture take root, transcending generations.
Chairperson Tamura delivered a message on the revision of the quality policy at the Group's annual quality promotion convention, and sent posters and explanatory materials in Japanese, English, and Chinese to all the bases in the Group. Moreover, the Group ran an article on this issue in the company newsletter to ensure that all employees are informed and that the revision becomes widespread.

Quality Assurance System
The Tamura Group has established the quality assurance system applicable to each business characteristic of electronic components, electronic chemicals/FA systems, and information equipment in order to respond to all needs of customers in various business fields. Furthermore, the Quality Control Committee holds meetings eight times per year, during which the quality assurance managers from all the Group’s businesses attend and share its quality information to work on preventive measures for quality-related problems.

◆Status of Acquisition of Quality Management System Certification
The Tamura Group has acquired ISO9001 certification at its factories and affiliated companies. ISO9001 is used for daily quality control, quality improvement, and prevention of quality issues. It is the key to our quality management activities that allow us to provide products that satisfy our customers.

Efforts in quality improvement

To uphold the policy of “Manufacturing excellent products,” the Tamura Group has been promoting various quality improvement activities to further increase customer satisfaction, while endeavoring to establish the optimal quality management system for each business segment.

◆Quality Training Program
By identifying human resource development, which is essential for quality improvement, as a priority issue, the Tamura Group redeveloped conventional quality-training programs in 2017 and started to implement them sequentially in order to improve employees’ capabilities and enhance the operational level of the company-wide quality management system. In FY2020, faced with an extraordinary environment on the back of the COVID-19 pandemic, the Group took thoroughgoing infection prevention measures including making use of remote work online, and carried out a series of programs, such as the Design Review Practice aimed at improving the product design process, a lecture on how to teach work to improve the manufacturing process, basic training for quality enhancement intended for young employees, and a program to help employees obtain QC qualification, as originally scheduled. The Group will continue to promote training and educational programs by job rank or type further, thereby undertaking its quality improvement initiative continuously.
