In the word of mathematics, the symmetric structures on spaces are described by groups.
We call such symmetric space a space with group action.
My research interest lies in geometry and topology of the spaces with torus actions.
In this decades, the area so-called toric topology has been emerged.
Roughly speaking, toric topology can construct bridges among different areas (geometry, algebra and combinatorics) by the study of the spaces with torus actions.
In the near future, I would like to continue to study toric topology more deeply and challenge to solve open problems.

Algebraic Geometry is a field in mathematics that studies geometric objects defined by polynomials. Since polynomials are used in the definition, algebraic methods can be used to study the geometry.
The main objects that I am interested in are rlow dimensional objects such as algebraic curves and surfaces. I try to find “invariants” that can be used to distinguish similar curves, thnik of the “exsitence problem” which asks wheter curves satisfying given conditions exist, and once we know the existance, considr the “construction problem” in which the goal is to explicitely write down the equation. Since explicit equations appear, I sometimes use computers in order to execute my calculations.

Even if you think you understand it, if you look at it from a different perspective, you may find some unclear points.
We are researching the construction of an easy-to-understand learning system that makes difficult-to-understand teaching materials easier to handle, encourages confirmation from multiple perspectives, and is easy to understand.
Based on conventional CAI and e-learning methods, we aim to build and release learning support systems such as algorithms and programming.
We are also researching a system that presents answers to simple puzzles in order to cultivate logical thinking.

This study aims to cultivate management curriculum abilities though the Social Teacher Lesson．The study consisted of the following three steps.　First I encouraged the student to reflect on their own perceptions on the meanings of learning．Second, their own views of social studies and theories of teaching were relativized by learning about multiple theories of teaching with different goals. Finally I made them understand the importance of engaging in teaching materials study and content construction in accordance with subject objectives, using as material subjects．

I am interested in English education in general, and I have conducted listening research focusing mainly on rehearsal speed and processing speed. I am examining the authentic use of English in countries and regions around the world, using research on World Englishes.
I am also interested in research on the relationship between speed-reading and listening comprehension with an awareness of English word order.
Currently, I would like to conduct research on the changes in English education in elementary, junior high and senior high schools due to the revision of the Course of Study, and on how to personally and professonally develop future English teachers at universities.

I am engaging in research on intercultural contact and acceptance from the perspectives of psychology and pedagogy and English language education. In Japan, the proportion of foreigners in the total population is expected to increase to 10.8% by 2070 (Ministry of Health, Labour and Welfare, 2023), and measures for living with foreigners in the community will be increasingly required in the future. I am promoting research on intercultural psychology and intercultural education practices in order to contribute to the promotion of intercultural understanding education and English language education.

My research centres on the questions of cultural identity and transnationalism in contemporary East Asian cinemas, with a particular focus on the works of Okinawan filmmakers and the cinematic representations of Okinawa since the 1972 reversion. Recently, I have also been examining transnational film adaptations of Haruki Murakami’s works.

I analyze influences of biogeographic phenomena such as evolution and migration of host animals on parasite distribution or population using molecular phylogenetic analyses. I’m also conducting research on the mechanisms of migration and pathology of helminths in their host.

Pathology is the study to investigate the causes and mechanisms of wide variety of diseases.
My activities involve;
■Diagnostic pathology of various animal species especially companion animals.
■”Cosmetic autopsy”: this is an animal-owner-friendly procedure while maintaining scientific/medical robustness.
■Establishment of veterinary forensic science in Japan.
■International cooperation: I used to work in Laos (in Southeast Asia) for 3 years as JICA volunteer and in US for 3 years as veterinary pathology resident at Purdue University (in Indiana). Living abroad is always fun and challenging!
■Development of new career path for veterinary students.

Alzheimer’s disease (AD) is one of the major causative diseases for dementia. Characteristic AD pathology, such as amyloid plaques and neurofibrillary tangles, are observed in aged animal brains, suggesting that AD pathology would be the sign of brain aging. Zoobiquity is an approach to investigate and treat diseases without any distinction of species. I have been working on the studies to clarify the mechanism of brain aging and the pathogenesis of AD by using nonhuman primates. I am also interested in how neuronal activities affect membrane traffic system in neural cells.

It seems to be common knowledge today that human rights are universal. However, despite the universality of human rights, discrimination based on race and gender, as well as human rights violations arising from religious backgrounds, continue to occur in the international community. One of the reasons behind this problem is the opinion that although the concept of human rights itself is universal, the particular circumstances (cultural) of each region in the international community are different, and therefore it is not really possible to implement human rights with the same standards in all regions. I believe that the universality that human rights possess is not necessarily in conflict with the particularities in a region. In order to pursue and clarify this view, I am researching how human rights (international human rights) should be addressed in the international community (methodology). The study examines this concept from the perspective of whether it is compatible with the universality of human rights. We also study what grounds the universality of human rights. In particular, we are studying whether the Universal Declaration of Human Rights (UDHR), which was the starting point for the numerous international human rights treaties created mainly by the United Nations, can be recognized as customary international law today.

My main study is on German Literature, German Romanticism, and on the filmstudy about Germany and Ireland. I have studied for many years German romantic Literature, especially Novalis, Tieck and Eichendorf. In recent years I have studied German silen film, Friedrich Murnau and Fritz Lang, etc. In pararell with Filmstudy, I am making research on the probaebs of the world.

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.

I have wide experience in teaching English in several types of schools such as junior high and high schools, including a correspondence course high school, and a university. So, in the field of English Language Education, I am interested in how to improve English language skills of EFL learners at each stage of language learning and lead them to be self-disciplined learners from the viewpoint of SLA.
In one case, learners at the higher education, e.g. university students, are required to read several literatures in order to gather information or knowledge on their interest. Some literatures may be written in Japanese, but in most cases, they are written in other languages, including English. I am investigating some possible aspects related to their effective reading, such as formal instruction, vocabulary building, background knowledge etc., and would like to identify aspects effective to reading for information gathering. These aspects may vary according to learner characteristics. In another case, I am performing studies of effective use of media such as music and movie in the language classroom.
Moreover, I would like to investigate the potentiality of BASIC English, which was “discovered” by Charles Kay Ogden, and develop educational materials for EFL/ESL Learners based on Ogden’s idea shown in BASIC English. BASIC English is a simplified and organized English brought up by Charles Kay Ogden as an international auxiliary language, and as an aid for teaching English as a second language. I think his idea is still very significant even today.

It is said that an increase in motivation to learn leads to effective learning in various situations, including the acquisition of a foreign language. Particularly in foreign language learning, the environment and learning experiences are closely related to learning motivation. I aim to clarify what kinds of learning experiences lead to high motivation for learning and to construct a framework for effective classes.
I am also doing research on how to incorporate reflection into teacher training programs and professional development for foreign language teachers. This will enable them to improve their own teaching practices through self-reflection and reflection with others.

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.

In order to revitalize the rcommunities, many municipalities with declining populations are making efforts to utilize the “history” and “culture” of the region for community development and tourism. However, first of all, it is necessary to academically clarify what are the characteristics of history and culture of the region, and to think of effective ways to use them. The center conducts measurement surveys of historical buildings and townscapes to study the value of cultural assets and methods of utilization, and reports and makes proposals to prefectures and municipalities. We are also promoting research on the utilization of cultural assets at an academic level with the aim of contributing to the local communities, we are training and educating human resources with the ability of “cultural thinking ability” which means to see and think about things from a new point of view with understanding of coexistance and interdependency included in the concept of culture based on the understanding of what is culture. Overseas, we are transferring this technology and training engineers in the Philippines, Bhutan, Fiji, etc., making use of our original restoration method based on surveys of traces.

　I do research the image processing using color effects and visual characteristics. For example, the human visual features vary with on age. I advance the development of a lightness transform method considering the visual features of the elderly person.
