Education at a graduate school in Japan has been traditionally oriented for lecture-style courses, beside thesis works. Toyota Technological Institute has been adopting the practice-based courses including the internship program for undergraduate students since the Institute started in 1981. These practice based courses for undergraduate program are the requirements for graduation. The outcome of this unique educational system has yet to be evaluated, but it is our belief that in view of a coherent educational curriculum, such practice based courses including an internship program is also necessary for graduate students as well. In particular, students in engineering and science fields need to be exposed to activities outside the campus as developments in those areas are very rapid and significant. It is our expectation that through such practice based courses together with advanced lecture-style ones, students will have more opportunities for training the abilities that are necessary for leaders in a global environment.
