Sumitomo Business Philosophy
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). Based on the "Monjuin
Shiigaki" (“The Founder's Precepts"), it has been deepened over generations. 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.
Article 2. Sumitomo shall manage its activities with foresight and flexibility... Under no
circumstances, however, shall it pursue easy gains or act imprudently.
— Quoted from the Sumitomo Goshi Kaisha Administrative Regulations
(1928)
