We have established the corporate philosophy of the Institute of Quality and Technology in the form of a company motto, and have clarified the company’s goals, policies, and attitudes toward work.

This is an action guideline as an employee of the Institute of Quality and Innovation.


We, Nagoya Quality Assurance Technology Co.,Ltd., define the symbol mark as shown on the left.

The symbol mark is a representative design that simply expresses the characteristics of our company.

To date, we have played the role of “inspection” and “quality assurance”, which are the last bastions at the manufacturing site, based on the aerospace industry.
Its role is a great responsibility that integrates “honesty, precision, and responsibility.”

The symbol mark expresses the “QAT” of our company name “Quality Assurance Technology”, and at the same time, it is an acute-angled design that goes upward, and the meaning of “Ken” that makes us our company is included.

It is our mission as a group of quality assurance specialists to set high goals and strive to improve our technology.
