The Keio University Graduate School of Business Administration, also known as Keio Business School, is Japan's oldest business school, founded in 1962. The School has been referred to as "KBS" from its founding, and today, KBS provides three degree programs i.e. a full-time MBA program, an Executive MBA program, and a PhD program; and open-enrollment executive programs. The masters' programs of KBS develop leaders proficient in their respective areas of specialty with core management skills. We call this character "the T-shaped development model. The horizontal bar of the letter T corresponds to the core management skills developed through mandatory courses covering eight major managerial areas, while the vertical column represents in-depth knowledge and functional expertise developed through specialized courses and other academic activities. Finally, on top of such managerial skills and knowledge, a leader must have a certain mindset, which we believe are most-effectively developed by the use of the case method. The above-described knowledge, skills and mindset should be up-to-date to prepare our graduates ready for the business world. We attach importance to a balance of theory and practice, thus encourage our faculty's research on business practices linked with academic theories and vice versa. Such our view in management education and research is well represented in our mission statement: KBS develops leaders who can envision and materialize original business concepts. Here, scholars and students of diverse backgrounds find enjoyment in learning together, delivering world-class research, and integrating academic theory with business experience.
