・Cleanliness Class 1
Cleanliness Class 1 is the production area with the highest cleanliness. This is the area that a worker may come into direct contact with the product during the process such as measuring the weight of the materials.
・Cleanliness Class 2
Cleanliness Class 2 is the production area where the intermediate inspection for the outward appearance is done, and where the final product is completed by being packaged.

・Cleanliness Class 3
Cleanliness Class 3 is the area where the observation paths, offices, dining hall and meeting rooms are located.
Here, the visitors are permitted to move around in plain clothes.

・Air Pressure Control

The air pressure in the production area is controlled to be positive, higher than that of the area outside. It is controlled so that outside air or dust will not come in through the gaps between walls and ceilings. The air is also designed to flow from the area with higher cleanliness class to the lower, thus making contamination hard to occur.

There are changing rooms which are designated for each area of cleanliness classifications. Also, for the area of cleanliness class 1 and 2, the way of dressing and the entrance to the production area are different. To enter into the area of cleanliness class 1 with the highest hygiene, you must go through a primary changing room, primary hand washing room, secondary changing room, secondary hand washing room and an air shower.
