Plant Policy by the Plant Manager
With the motto of “Let’s advance production innovations, business innovations,and process innovations with the culture of ABC” (atarimae, bakashojiki, andchanto, or in English: to diligently and properly perform all routine but
necessary tasks), we are working to entrench this ABC culture at Mizushima
Plant and achieve these three types of innovations.
I believe that the basis for offering products of stable quality while placing thehighest priority on safety and environmental protection is employees’ full andCorporate Officer and Mizushima
Plant Manager
steadfast compliance with laws and regulations and adherence to theTomoyuki Kose
procedures, rules, and other matters that they have decided.
We have established the Monozukuri Training Center at Mizushima Plant to provide company-wide operator
education. The center accepts trainees from each plant and conducts basic education for working in achemical factory to ensure that Zeon operators can perform the routine but necessary tasks.
We are working to gain the trust of the local community and the wider public with a commitment to safe andstable operations achieved by entrenching the ABC culture and achieving the three types of innovations at
Mizushima Plant.
