Corporate Philosophy

atsushi okuno

Keep going forward with customers

SANKO has established as a trading company for graphite parts, semiconductor-manufacturing parts and related components. In order to respond flexibly to customer's requests, we changed our mind to challenge "Product Manufacturing" by ourselves. For customers and stakeholders, we also focus on "New Materials" and develop novel products with its idea.
To make a contribution for the development of customer's product-manufacturing, we all have faith and evolve our technical and servicing capability.
SANKO keeps going forward with customers.
