Introduction
Introduction
"For future machine in harmony with earth"
Mechanical systems have become complex and multi-functional over the years, and the field of mechanical
engineering has become specialized. The Department of Mechanical Science and Engineering is looking to cultivate
scientists and engineers who can create innovative devices and systems which can deal with these complexities.
To contribute academically to the development of such dynamically changing fields, three divisions (Mechanical
Science, Mechano-Informatics and Systems, Mechatronics) in the Department carry out their individual studies
interacting with each other.
In the master's course program, we provide a wide variety of courses in both fundamental and applied mechanical
engineering. Graduates are expected to become leading research engineers who can achieve goals effectively in
industry. The PhD track is designed to help students become researchers who can shape the future of society and
develop unique technologies to realize it. We expect PhD students to be scientists who find and pursue their own
research, have excellent leadership, and evolve mechanical engineering in academia. We also train all the students to
be professionals who have humanity and ethical view.
The Department promotes international student exchange. We offer various scholarships through various programs
such as Global Center of Excellence (GCOE) for PhD students and Japan-US Advanced Collaborative Education
Program (JUACEP) for master's course students. Both Japanese and foreign students are highly encouraged to
apply to gain new experience and broaden their scope.

60% of undergraduate students in the Department Mechanical Science and Engineering continue on to the graduate
program in the department. Three year of research experience (the last year of the undergraduate program and two
years in graduate school for the Master's course) enables students to earn fundamental knowledge and skills towards
becoming leading engineers of the future. About 8% of the Master's course students proceed to the PhD course. A total of
six year experience enables them to be scientific researchers who can open new windows in engineering. The rest of the
Master's course students find jobs in industry after graduation. They work nationwide in various fields; from automobile
and aerospace/astronautics to heavy industries, electronics and IT companies, etc. Their promising works have often
been recognized as the top quality all over the world.
