The fundamental principle of the Keio University Graduate School of Business and Commerce is our founder's 'Spirit of Jitsugaku,' which we continue to embrace. 'Jitsugaku' is a way of learning about the worldview by Keio University's founder Yukichi Fukuzawa through the application of reason, observation, and verification. Jitsugaku is science in the truest sense of the word and a powerful tool in Keio University's never-ending search for practical solutions to real-life problems.
