Once a year we have a big cleaning day. This year it took place on January 5 Every employee regardless of rank or position has to be involved in this activity As a result of our everyday 25 (Seiri & Seiton) work policy, it took only two hours to clean up the entire place-inside and outside the factory. Not only did it make our workplace clean, but this activity also promoted teamwork for taking care of things, and sharing space.
