Features of my courses

Cultivation methods have been improved by farmers and researchers with many years of experience, wisdom, and ingenuity; they are continually improved by supplementing new knowledge and technologies. By teaching contemporary understandings of cultivation methods, these courses encourage students to have their own perspectives on the future of agriculture and food production.

Key words for research

Environmental stress and crop production, Genes and plant physiology related to salt tolerance

What I like about Discovery

By exchanging opinions with students with various interests, you can broaden your knowledge and perspective after entering this course. You can also gain a wide range of specialized knowledge because you can take lectures from multiple faculties depending on your interests. If you find a faculty that suits your interests outside of the Discovery Program, you can pursue your graduation thesis in that faculty. I think the program is very attractive to students eager to actively pursue their education.
