Guidelines on purchasing work

These guidelines were formulated in 1998 based on our internal "purchasing management regulations" as code of conduct guidelines for all employees involved in purchasing work in order to maintain transparency in business partner selection and prevent risks before they occur.
Based on these guidelines, we conduct purchasing work that ensures fairness, clarity, and rationality and compliance with the law, from the perspective of the "corporate citizen" ideal extolled in our management philosophy.
