The various Mitsubishi group companies are breathtakingly diverse and involved in a vast range of businesses. Yet, despite this great diversity, all group companies maintain one common philosophy that continues to underlie their activities, even after more than 150 years. That shared philosophy is encapsulated in a creed articulated by the fourth president of the Mitsubishi organization, Koyata Iwasaki, in the 1930s. Today this philosopy is referred to as the "Three Principles" (called "Sankoryo" in Japanese). Although more than 80 years have passed since the philosophy was codified, the spirit and values of Sankoryo remain alive and current today in Mitsubishi group companies, both in their business dealings and their activities aimed to help society.
"Shoki Hoko"=Corporate Responsibility to Society
Strive to enrich society, both materially and spiritually, while contributing towards the preservation of the global environment.
Commerce is a public undertaking and one requiring corporations to take responsibility for many of the interests affecting the countries in which they operate. This philosophy has been a cornerstone of Mitsubishi's management policies from its beginnings. In order for a corporation to create sustainable prosperity, it is essential that it operates in a manner that is conducive to achieving this goal for the greater society.
"Shoji Komei"=Integrity and Fairness
Maintain principles of transparency and openness, conducting business with integrity and fairness.
President Koyata was known to have repeatedly cautioned Mitsubishi managers against focusing blindly on profits and losing sight of the Group's adherence to a high standard of ethical behavior amid unprecedented competition, urging them to respond to competitors' unscrupulous business practices with integrity and forbearance. He reminded them often of the importance of meeting the expectations of their customers and the public by exhibiting high ethical conduct in all their transactions. He was also well known for his observance of cultural differences around the world and the local customs of the communities in which Mitsubishi conducted business.
"Ritsugyo Boeki"=Global Understanding through Business
Expand business, based on an all-encompassing global perspective.
At the outbreak of the Pacific War, President Koyata made a bold statement about the friendship between international business partners now separated by war: "We count many British and Americans among our partners. They have undertaken many projects with us and so should peace come again, they will once again become good and faithful friends."
