Quality Assurance
Basic Approach
Quality Policy
Yokowo is committed to achieving quality that delivers customer satisfaction. To do that, we respond diligently to the development and improvement requirements of the world-class companies that are leading the global technological revolution, establish optimal quality standards for all products we produce, and make effectively use of our proprietary technology.
Quality Control Activities
Since its founding, Yokowo has been carrying out exhaustive quality assurance activities through quality management with the view to becoming a supplier of top-quality products. Yokowo was certified with the ISO 9001 in 1995 and, subsequently, with the QS-9000 in 1999. Yokowo shifted from its certification to the IATF16949 certification in 2018.
Additionally, Yokowo's principal production bases in Japan and overseas have obtained the ISO certification and the Yokowo Group as a whole implements quality assurance activities in an effort to boost customer satisfaction.

Major Initiatives
Exhibition Room for Past Troubles*
Our Quality Assurance H.Q. has set a slogan, "Create a quality culture that will not let past troubles be forgotten," under which it drives activities to raise the awareness of all employees.
It exhibits actual goods involved in past quality problems and explains them using videos and panels. The exhibits are revised twice a year. Each time they are revised, all employees are given time to see them.
* The term "past troubles" refers to a record of quality problems that occurred in the past.
QC Circle Activities
We are committed to QC circle activities. The improvement efforts are continued at each workplace and have proved effective. Moreover, we hold a biannual company-wide session for presentations by teams that have won block competitions, with the participation of senior management.
Reliability Test
Yokowo has introduced a large number of environmental composite testers and other testing equipment to its Reliability Laboratory and is constantly working to supply premium-quality products that are compatible with the latest technological innovations.
