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.

The field of my research is part of the qualitative theory of ordinary differential equations. In this research, we focus on the behavior of all solutions of nonautonomous ordinary differential equations. How does the variable coefficients of ODE influence the stability of the solutions? The main purpose of this research is to answer this question. In particular, we deal with the problem on the stability in the Lyapunov sense. For example, we treat asymptotic stability, uniform asymptotic stability and exponential stability. By understanding these essence, we aim to contribute to the development of ODE.

The main theme for my research in mathematics is “spaces with symmetry”. I am particularly interested in the field in which algebra, geometry, and combinatorics (three different kinds of mathematics!) intersect all at once. For those area of mathematics, it is often happens that a single phenomenon has many ways to be viewed; it can have geometric interpretaions, representation theoretic interpretations, and combinatorial representaions. Through these experience, we can feel the richness of mathematics. In particular, it is exceptional when we can express abstract geometric/topological quantities in terms of concrete algebra and combinatorics. Recently,I am particularly interested in the geoemetry and topology of Hessenberg varieties.

Tsunami deposits are useful in attempted reconstructins of prehistoric tsunamis. Geological analyses of tsunami deposits can provide estimates of several parameters of tsunamis, such as recurrence intervals and inundation areas. To assess the history of paleotsunami, we investigate the tsunami deposits around the coastal lowlands on the eastern margin of the Sea of Japan. These studies provides useful information for advancing tsunami disaster risk assessment in coastal lowlands.
In addition, we are active in the practice of disaster education.

Primates (precisely non-human primates), are the animal group that shares the most similarities with humans. They show high levels of intelligence and social skills. Additionally, many primate species live in tropical and subtropical regions and are considered keystone species that play a fundamental role in maintaining tropical ecosystems. Researching the society and ecology of primates can provide us with valuable insights into the evolution and nature of humans. This knowledge can help us better understand ourselves, as well as contribute to the conservation of biodiversity and the resolution of global environmental issues. My work involves studying the society and ecology of primates and other large and medium-sized mammals, mainly through field observations. I also examine human society from a zoological perspective and its evolution. Currently, my team and I are conducting long-term field research and conservation activities to protect wild gorillas in the tropical forests of Central Africa. We also conduct educational and animal welbeing activities in zoos and perform behavior observation research on Japanese macaques in Japan.

In the design of public cultural facilities, there are an increasing number of examples of design methods that incorporate the users’ ideas at the architectural design stage in order to promote active use.
Our laboratory has collected 70 cases of participatory design from all over Japan. The following participatory design practices were implemented in our laboratory, and the effectiveness of participatory design was verified through analysis of user opinions and post-completion evaluations of these practices.
・Kudamatsu City Community Exchange Center (2013)
・Okayama Prefectural Doctor’s Hall (2015)
・Sanagouchi Village Office (2017)
・Kashiwa City Southern Neighborhood Center (2018)　

Study and practice on design methods of architecture in the context of urban space, public space, strategic urban regeneration by micro-intervention.
The main emphasis of my laboratory is to grasp architecture in the context of urban space and social situation, and use this for the basis for constructing both a new design theory and practical architectural projects.

Our group is interested in developing new synthetic methodologies to enable synthesis of biologically active natural compounds and their derivatives in environmental friendly manner. As such manners, we have developed metal-free regioselective cycloaddition of highly reactive o-quinone to form 1,4-benzodioxane and a procedure for construction of benzene ring from o-quinone and terminal alkynes through cycloaddition and photo-decarboxylation. We have also reported concise synthetic route to KDO, a kind of carbohydrate, including elimination of cyclic sulfite as a key step. By collaborative research with a company, functional monomers for dental adhesive resin cements have been developed. 　

We have to evaluate the occurrence prediction and disaster occurrence risk of landslides from inspection data. We analyze the trend of the past of the disaster, to assess whether the “when” “where” landslide disaster occurs, we are working to hazard maps.
These results are considered useful in a safe life.

Music instruction is conducted not only through words, but also through various non-verbal means of expression, such as eye contact, gestures, and facial expressions. We are collecting and studying objective data on what music teachers look at and how they use their bodies in response to what situations, using eye-gaze measurement devices, motion capture, etc. We are also collecting data on the actual status of music teachers’ nonverbal communication by comparing these data with the results of interviews with teachers. By comparing these data with the results of interviews with teachers, we aim to elucidate the actual state of nonverbal communication among music teachers.
We are also conducting research on the relationship between music and physical expression.

I am interested in teacher involvement in supporting children’s social-emotional development. School is not only a place to develop academic skills, but also to promote children’s social-emotional development. So, what kinds of teacher involvement contribute to the development of children’s social-emotional competence? I am collecting and analyzing data on these questions.
I am also developing programs to foster communication skills, etc., with reference to psycho-educational programs that foster knowledge and skills related to the mind and social-emotional learning (SEL). These programs are meant to “prevent” problematic or maladaptive behaviors before they occur. I am also interested in how to utilize such programs in actual educational settings.

How can teachers motivate learners towards meaningful inquiry and research based learning? Should teachers teach, facilitate, or both? How can interactive, proactive student co-ownership of learning and assessment be realized? These are my primary inquiry questions in the field of teacher education.

My primary inquiry interests in Japan Studies and social studies education are as below: How do local policy and business models come together to bring about regional revitalization? How can we implement case studies in this area in secondary school education, and Japan Studies education?
Analysis of animism in Shinto, Hinduism.and Japanese Buddhism.

In response to the crisis of social, cultural, and economic sustainability in rural areas caused by declining birthrates and aging populations, the regional management movement, in which industry, academia, government, and the private sector collaborate to solve problems, has attracted attention.
In this laboratory, we support the construction of marketing databases for tourism marketing organizations that practice regional management, while analyzing the information obtained from these databases and examining effective regional management strategies.
There are two topics in this laboratory,
(1) Research on the relationships and roles among entities in effectively functioning regional management,
(2) Research on the construction of a marketing database that contributes to the formulation of regional management strategies and on evaluation indices for regional management.

I collect various data on people’s behavior, attitudes, and psychological states, and conduct research to explore relationships among variables. I focus on social science research methods such as questionnaires and online experiments, but I also aim to conduct research in collaboration with adjacent fields such as humanities and engineering.
In particular, I am interested in understanding mechanisms by which people in a position to evaluate and make choices, such as consumers and users of services, compare objects and make decisions. I am currently focusing on the following research topics. (1) Research on mechanisms by which consumers compare and select products and services bearing brand names or proper nouns such as names of places or people. (2) Research on mechanisms by which tourists, current residents, and prospective residents evaluate attractiveness of regions such as prefectures and municipalities. (3) Research on mechanisms by which users evaluate satisfaction with SNS, the Internet, and services using 5G technology.

I am researching on Value Co-creation Marketing, targeting tourism industry and it was found by providing service of society. The research is related to the SDGs “Goal 17 achieving the goals of parteners. Goal 17-17 promotes the public, public-private and civil society partnerships effectively. It based on the experiences of various partnerships.”
It is important that not only contains hospitality spirit of traditional Japanese, but also to estabilish a system of practice. Therefore, I am going to devote to format the partnership between all participants undering case study. Providing conceptualization and theorization of “realiation of happiness “system to clients (e,g,tourists).

My research focus on practice of Capacity Development for student’s leadership development and professional development of Faculty and staff at university. I was organized leadership development program and system at “University Network for Global Leadership Development in West Japan” that grants by Ministry of Education, Culture, Sports, Science and Technology in JAPAN.
And I have collaborated project with many universities approach to administration and curriculum management by supervision and lecture.
In these days, I expand of my research fields on Management of company and Government. And I am carry out research Capacity Development organization members (student, Faculty, staff, officer and more) at empirical research methods that utilized university resources.

Our laboratory has developed molecular and crystal structure models made from inexpensive and readily available materials, including cardboard, electronic components, and LEGO blocks.

The difficult past was a catastrophic event that led to “mass death,” and the damage was felt not only by the dead but also by the survivors. This applies to wars, pollution damage, isolation policies for Hansen’s disease, pollution damage, etc. Furthermore, because such damage involves a complex relationship between perpetrators and victims, the “interpretation = meaning” of the event is likely to be divided depending on one’s position, making it difficult to pass on experiences. Based on the concepts of collaboration and ESD, I create spaces for dialogue, practice public history, and deepen my research on the inheritance of difficult past experiences.

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).
