Our Philosophy is based on Sumitomo Business Philosophy, which has been passed down from generation to generation throughout Sumitomo’s 400-year history.

Sumitomo Business Philosophy was first proposed by Sumitomo Masatomo (1585-1652), the founder of Sumitomo Group. It is a concise explanation of the business acumen he left behind for posterity. Based on the “Monjuin Shiigaki” (“The Founder’s Precepts”), it has been deepened over generations by Sumitomo's predecessors. The gist of it has been carried over as the Business Principles.

Article 1. Sumitomo shall achieve strength and prosperity by placing prime importance on integrity and sound management in the conduct of its business.

Article 2. Sumitomo shall manage its activities with foresight and flexibility in order to cope effectively with the changing times. Under no circumstances, however, shall it pursue easy gains or act imprudently.

-Quoted from the Sumitomo Goshi Kaisha Administrative Regulations (formulated in 1928)
