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.

My field of expertise is algebraic geometry. There we consider a set of zero points (algebraic variety) of polynomials. For example, lines, circles, hyperbolas, and parabolas are algebraic varieties. The set of all geometric objects with certain properties is called a moduli space.
Moduli spaces of stable vector bundles on complex algebraic surfaces X are actively investigated as concrete examples of algebraic varieties.

For an algebraic variety M, the Kodaira dimension is determined.
The Kodaira dimension of M is an important invariant related to the curvature of M. Also, there is the minimal model theory to understand higher dimensional varieties. In this theory, one simplifies a variety by exploding and contracting its subspaces to get a simple variety, called minimal model.

I am interested in singularities, the Kodaira dimenson and the minimal model program of moduli space M.
(1) For large classes of surfaces X, I described the minimal model program of M by using words of moduli theory.
(2) I examined singularities of M, and in case where the structure of X is relatively simple, I showed that singularities of M are “good”. As a result, I calculated the Kodaira dimension of M.

The landscapes of traditional townscapes and villages are based on the natural conditions of the land, such as climate and topography, and are the tangible manifestations of social characteristics such as history and livelihoods, which have been inherited through traditional lifestyles and local traditions. In our laboratory, we are conducting research to clarify what kind of background has formed such a beautiful landscape, and what kind of elements it is composed of, fucusing on the characteristics of the traditional architecture of the region. We are also examining methods of heritage conservation that involve local residents in order to inherit these cultural heritages to future generations.

“Home economics” in school education aims to improve the skill of homemaking through the velationships between oneself and their family, their consumption habit, their eating habit, their dwelling life, their clothing life and so on.
“Home economics” is concerned with not only our claily life but some subjects life social studies and science. Moreover it’s very important to reflect on your home life so far.
I investigate how “Home economics” should be and I design exciting, satisfactory and practical classes.

The founding of Workers’ Educational Association (WEA) in 1903 is situated in the social development of the working class organisation and is sustained the rich associational culture. In my research, I apply on the focus to the working-class association which was affiliated with WEA and the adult students who came to class. What was contributed to the educational life of the workers? What was the WEA’s purpose in putting forward the educational reconstruction? I will try to explore this.

The concept of gender is incorporated into literary and cultural studies, and is perceived as a mode in which it functions in a complex manner based on its relationship with various non-gender differences.Toshiko Tamura (1884-1945), who is said to be the pioneer of female writers in modern Japanese literature, moved to Shanghai in 1938 and launched the Chinese magazine “Women’s Voice” for Chinese women on May 15, 1942.Many Japanese and Chinese literary figures are incorporated into the language space of “Women’s Voice” published until July 15 after Toshiko’s death.By deciphering the language acts of both countries developed against the backdrop of the tense international situation, I am studying the language space surrounding “female voice” in wartime Shanghai from the variability of gender systems.

This study is about sentences which express emotions in modern Japanese. Modern Japanese studies verse mainly on predicate sentences. Such sentences aim to convey information about “things”. As such, there are scarce studies about sentences which express emotions being treated as a kind of sentence of its own. These sentences do not aim to convey information of the “thing”. An example would be “Beautiful flower!”, which is uttered unconsciously upon being moved by the beauty of any given flower. This type of exclamatory sentences are uttered by speakers to express their emotions and they employ the structure of Noun Phrases. Other kinds of sentences which express emotions are Labeling Sentences like the insult “Bakayaro!”. Since systematic studies of sentences which express emotions are scarce, I would like to attempt to describe and classify them, considering Labeling and Exclamatory sentences as separate sub-groups.I am also attempting to grasp the structure of modern Japanese sentences, not leaning on the structure of predicate sentences.

More than 200 herpesviruses have been discovered and most of them have very limited host range. Therefore, there are many herpesviruses which have not established cell culture system to replicate or system to evaluate the pathogenicity of the virus using experimental animals. Without these systems it is impossible to analyze the precise mechanism of viral replication and pathogenicity. Thus, I aim to unveil the determination mechanism of host specificity of herpesvirus by analyzing the interactions of virus and host factors by using recombinant viruses. In addition, I also study epidemiology of herpesviruses.

As SFTS virus seems to be spread in Ehime, our lab focuses on SFTS virus. I compare the pathogenicity of SFTS virus and its related virus, Heartland virus and analyze which factor causes the difference.

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.

(1)I have been conducting research on Virginia Woolf, who is one of the greatest writers of the 20th century. I have been studying her representative works from the viewpoint of psychoanalysis, especially Carl Gustav Jung’s analytical psychology. In addition, my recent research interests include history, society and culture described in her works.
(2)I am interested in English language education. I have been working on the use of films (including anime), graded readers and literary works in EFL classrooms. My research focuses on students’ motivation in language learning.

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.
