◆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.


In FY2022, we will continue to promote awareness and penetration activities using short explanatory videos, in-house newsletters, etc. Additionally, based on top management's quality review, we created and deployed a checklist and began activities to quantitatively judge and improve the level of penetration in each department. We will continue to work to further improve quality awareness throughout the group.

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.
To meet the needs of our customers who order products for automobiles, some facilities have also acquired IATF 16949 certification (a quality management system for the automobile industry).

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
Positioning human resource development, which is essential for quality improvement, as a priority issue, we established a quality education system in 2017 in order to improve the abilities of each employee and raise the operational level of the company-wide quality management system. We have reorganized the facility and gradually put it into operation. In fiscal 2022, we will continue to provide quality education, mainly through "work instruction courses" taught by in-house trainers. Additionally, we have started holding regular quality lectures specializing in the themes of "problem-solving methods" and "design methods." We will further enhance company-wide quality education and engage in continuous quality improvement activities.

◆Quality promotion conference
At Tamura Group, we have designated October 4th as ``Tamura Group Quality Day'' and hold the ``Tamura Group Quality Promotion Conference'' every year to maintain our awareness of working toward quality improvement.
Continuing from last year, in 2022, we held the event in an online format to allow as many people as possible, including those from overseas, to participate. In addition, we have expanded the program, which previously targeted quality department managers as the main participants, to include all participants. At the outset, the chairman once again asked for improvements in operational issues based on the quality policy of ``manufacturing correct and excellent products,'' and it was a meaningful opportunity to reaffirm the importance of quality through the will of top management.

Efforts to Enhance Customer Satisfaction

◆Supply Chain Management Activities (MAPS* system)
In order to meet the demand of customers to deliver “the necessary goods in the necessary quantities, at the necessary time,” we have introduced the “MAPS System” for the integrated management of key business operations at sales offices and factories, both in Japan and overseas. Assessment index management has been implemented to ensure stability of the activities. At the same time, we have expanded MAPS introduction to the main offices and factories over seas in an attempt to level business operations and strengthen supply chain management.

* MAPS is the name of Tamura Group's Enterprise Resource Planning (ERP) system and is the acronym for “Management Accounting Production Sales.

Participation in Exhibitions
Intending to provide products and services that give higher levels of satisfaction, the Tamura Group proactively participates in domestic and overseas exhibitions to strengthen communication with customers. In FY2022, we participated in various online and physical-world exhibitions in Japan and overseas, and promoted the technological capabilities of “One Tamura,” attracting many visitors.
