Learn from History, Live by the Spirit
Sumitomo's involvement with copper mining spans over 420 years.
During that time, the business has faced several major challenges due to changes in external conditions. In each case, management responded to the changes with skill and tenacity to forge a new business with a revised strategy and organization. The enterprise's sustained growth has made a significant and wide-ranging contribution to the development of Japanese society.
Today, as the direct successor of Sumitomo’s original business, SMM once again draws inspiration from this illustrious history to move forward based on the Sumitomo Business Spirit.

Following years of war-torn strife, Japan moved steadily toward the Edo Period, an era of relative peace and tranquility. Around that time, the Sumitomo family firm succeeded in mastering the new technology of copper smelting. The start of operations at the Besshi mine later provided the foundations for business development.
Japan's economy recovered rapidly in the years following WWII. This led to demands from Western countries for Japan to liberalize trade and make its currency fully convertible. Japan eventually dismantled tariffs and promoted free trade. SMM responded by undertaking fundamental business reforms to ensure the company would be internationally competitive.
