Quality Control

Ohmura is unwavering in its commitment to quality


At Ohmura, we have always worked by a “quality first” policy. Our policy on quality is to achieve zero defects.

Our people struggle day and night throughout the production process to assure our customers that we can provide them with high-quality products with the aim of zero defects. And continuous kaizen improvement activities are a fundamental part of this commitment to quality.

One might think that it is virtually impossible to achieve the goal of zero defects. However, we will not hesitate to work toward zero defects even if it might generally be considered impossible. We will work with the short-term target, “How many days can we go with zero defects?” in order to try to achieve “zero defects for ever.”
