Abstract
Building upon the renewal of business ethics form the perspective of Thomistic Natural Law Theory in the wake of “The Vocation of the Business Leader,” this essay offers a contemporary explanation of business leadership. The missions of business Leaders are to engage the global economic and financial world on the basis of human dignity and the common good, supported by the spirit of solidarity and the principle of subsidiarity. This reflection offers business leaders three practical principles, (1) the principle of meeting the needs of the world through the creation and development of goods and services, (2) the principle of organising good and productive work, (3) the principle of creating sustainable wealth and distributing it justly. The author confirms that these principles comport with the management theories of two entrepreneurs in Japan, Kazuo Inamori (1932- ）who was a founder of KYOCERA Corporation and Masao Ogura (1924～2005）who created strategic system of door-to-door parcel delivery service, TAKYUBIN.
