Postgraduate Courses


Postgraduate Courses

We offer postgraduate programs for Master’s Degree, and the program consists of five courses; Biology, Biochemistry and Molecular Biology, Applied Biosciences, Agriculture and Horticulture, and Agricultural and Environmental Engineering. After the Master’s degree, the students can perform the Doctor’s program at the United Graduate School of Agricultural Sciences, Iwate University (UGAS). Hirosaki University is a member of the United Graduate School.


Master’s Degree

By coordinating the undergraduate education, more highly interdisciplinary and international education/research would be performed to develop high-level human resources such as

・A specialist who can contribute to the development of communities
・A highly skilled engineer with the ability to work all over the world
・A researcher who will explore leading-edge.

As a general rule, two years of study are required for a master degree. There is a teaching assistant (TA) program, which provides opportunity for students to assist professors with teaching or experiments with a salary.
