Basic Philosophy

NGK SPARK PLUG CO., LTD. regards all the value, expectations, and evaluations provided to customers through products and services, and all the people, goods, processes, and arrangements involved in producing them as "quality."
We are always conscious of making the best value for customers, and, aware that we are the ones who support quality, we continue to grow, ambitiously applying creativity and imagination to all operations.
We create value for customers in accordance with our Corporate Quality Rules and Corporate Quality Policy. We will continue to contribute to society with safe and trusted manufacturing, as well as the development of human resources who effectively and efficiently implement total quality management (TQM), which enables us to respond flexibly and promptly to the evolving internal and external business environment.

Quality Management System

NGK SPARK PLUG CO., LTD. strives under the main principles of our quality management activities (quality assurance, daily management, policy management, Small Group Improvement Activities, and quality management education), which are based on our Corporate Quality Rules.
We have obtained certification by the international standard ISO 9001 and sector standards such as ISO/TS16949 in order to meet the demands of customers and the various industries.
The “Quality Committee”, established as the company-wide quality assurance framework, is chaired by the Quality Control Officer and composed of the general managers. The Quality Committee directs and supervises total quality management (TQM) and quality risk.
In addition, QC Circle activities are positively conducted as Small Group Improvement Activities and play a role in promoting total quality management (TQM) activities. The “NQC* Central Committee”, which promotes QC Circle activities, continually works with QC Circle trainers and the expert advisors who support QC Circle activities to strengthen the development of human resources and organizations that continually support quality.
We also contribute to awareness of local quality activities through participation of outstanding QC Circles in many external QC Circle conferences to present their results.
* N stands for an initial letter of “Nittoku”.
