Research Interest

Economic Analysis of Waste Policy, Economic Analysis of Recycling Policy, Economic Analysis of Voluntary Approach in Environmental Policy

My research incorporates an empirical approach in studying how source reduction in waste may be achieved. Packaging waste and food waste are major targets of the studies using ecnometric methods and social experiments. Although reduction is the issue with top priority among the 3Rs of waste management (Reduce, Reuse, and Recycle), little practical progresss as been achieved in policy. For example, lesser use of packaging in products may make the product inconspicuous compared to rival products, so it is not easy for producers to choose a smaller package. The theme is all the more interesting because it is challenging.

Lectures and Seminars

Lectures (Undergraduate)
[ESD course (Faculty of Economics)]
Kobe University provides an educational program with the purpose of training students to take a leading role in contributing to the creation of a sustainable society. This program (Education for Sustainable Development) is a joint effort of the entire Kobe University. In the faculty of Economics, we provide courses in the form of ESD exercise 1& 2, an introductory course in social communications, and a practical course in environmental NPO business models(colse 2018). These classes adopt a workshop style and field exercises.


The ESD course has been designated as an advanced liberal arts course. Enhanced development of social skills and visions is expected through interaction with students and faculty members from various departments and fields. Experiencing active discussion within groups with diversity is encouraged.
