In July 2012, we specialized in the building materials business, commercial business and oil business, and started as a new Sotetsu Kogyo. In addition to the conventional sales of building materials and petroleum products, in our commercial business, we are focusing on selling environmental products in consideration of the global environment and people's health. We look forward to your continued patronage. Copyright © 2012 SOTETSU KOSAN CO., LTD. All Rights Reserved.
