My research focuses on understanding how people build relationships within groups and organizations, and how these relationships are maintained and transmitted over time, from the perspective of social psychology.
I have examined the structure of behaviors in Sempai-Kohai(senior–junior) relationships in university clubs and extracurricular groups, exploring how hierarchical relationships are formed based on different criteria, and how these relationships shape individuals’ behaviors and emotions. In addition, I have investigated how group formality—defined as the degree of clearly structured roles and rules—and patterns of interpersonal relationships influence both individual behaviors and group functioning.
More recently, I have studied skill transfer processes in non-profit organizations, analyzing how leadership skills and knowledge are passed on. In particular, I highlight the importance of sharing tacit knowledge, such as experiential know-how and interpersonal networks, which are difficult to formalize.
My research employs quantitative data analysis using questionnaire and interview methods, as well as the development of psychological scales, with an emphasis on capturing real-world issues in a measurable form.
In the future, building on my experience in supporting students with disabilities, I aim to explore issues related to disability acceptance, career development, and support systems, and to contribute to the development of practical support strategies in collaboration with educational institutions and local communities.

In the future society, collaboration between leaders and followers is important.
Therefore, it is important that leaders also learn about followers and learn about followership.
The human resources that companies look for in new hires will include an element of followership.
Mastery of leadership requires that you make your own changes in your own behavior.
It is necessary to look back at one’s own behavior, notice unconscious comments and actions, and change oneself.
We are currently conducting research on building relationships with others, developing oneself, and becoming self-reliant through leadership education.

The current society has been the era of the information-oriented society more and more. In addition, humankind is being confronted with a lot of serious issues, especially environmental problems. That’s why they have to try to solve them with the data processing and make decisions. In this sense, it is statistics education that is most important area in mathematics education in order for students to acquire literacy on the data processing and decision-making.
Hence, I focused on the development of statistics education. The objective of my research is to transform from calculus-centered mathematics education curriculum into statistics-centered one. The research methods for achieving this are to analyze and develop the curriculum. About the former, I am comparing Japan with New Zealand because Japan has to cope with globalization and internationalization from now such as New Zealand which has already had much experience on them. About the latter, I selected teaching unit (substantial learning environment) as the theoretical framework which shuttles and integrates between scholarly knowledge and craft knowledge (see Wittmann(2001)’s Figure).

Footprints are important clue for understanding dinosaur social life and their kinematics. I investigate footprints of the Lower to Upper Jurassic of Morocco, and Upper Cretaceous of Mongolia.
In 2013, Okayama University of Science and Mongolian Academy of Science on paleontological research and　education. We execute joint expedition and multidisciplinary study on dinosaur and dinosaur bearing beds in the Gobi Desert.
I also study local fossils of Okayama, and visitor behavior in　paleontological exhibit of the museum.
Phogtograph: Parallel trackways of middle-sized Carnivorous dinosaur in the Gobi Desert. These trackways indicate the gregarious behavior of dinosaur.
