The Three Corporate Principles were formulated in 1934 as the action guidelines of Mitsubishi Trading Company (Mitsubishi Shoji Kaisha), based on the teachings of Koyata Iwasaki, the fourth president of Mitsubishi, as captured in a speech he delivered to the management staff in 1920.
Although Mitsubishi Trading Company ceased to exist in 1947, these principles were adopted as Mitsubishi Corporation’s corporate philosophy, and this spirit lives on in the actions of todayʼs management and employees.
