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.

After graduating from graduate school, I have spent many years teaching Japanese language arts at middle and high schools. During my long tenure at a middle and high school affiliated with an international school, I have reflected on and implemented approaches related to the International Baccalaureate program, interdisciplinary learning, and inquiry-based education.
Rather than being a literature enthusiast, I became a Japanese language teacher because I enjoy analyzing and refining logical arguments. My goal is to develop a systematic approach to helping students master Japanese as a language and to theorize the educational practices I implement in the classroom.
Think, Don’t Feel.
It is like a finger pointing away at the moon. Don’t concentrate on the finger, or you will miss all that heavenly glory.

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.

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.

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 specialise in English literature of the sixteenth and seventeenth centuries. Particular research interests include Fulke Greville (1554-1628) and the related writers. My current research involves investigating the ways in which Greville, through his works, criticises not only the Jacobean government, but also its monarch, James VI and I (1566-1625).　In order to analyse his writing process, I cross-reference the handwritten drafts of Greville’s works, the Warwick Manuscript (Add MS 54570). .

Satisfactory communication with others enables us to reduce interpersonal relationship stress and to enhance well-being.
Towards providing communication training that can help people communicate well, I have been studying verbal and nonverbal behavior of dyad, triad or small group in face-to-face and computer-mediated communication. For example, I examined what verbal and nonverbal channels were used by senders, and their channels had effectives on receivers in interpersonal persuasion.
I am currently studying communication behaviors and psychological safety during consensus building.

Public opinion is key word in mass media.Because this word is often used.But how the public opinion been formed? A gap between politics and public opinion is very important issue.How has mass media reflected the will of the people? The spread of the Internet has changed our lives. We study about new information age.

To survive, the firm needs to construct the new environment where it can achieve competitive advantage. To do so, it first redefines the meanings of the existing resources. After the meaning of a resource changes, the meaning of its resource dependence may also change. The firm makes sense of the context of resource and resource dependence to stakeholders. It then creates its own business model. I research on such firm that changes its project purpose, its strategy and its organizational structure flexibly, and the ecosystem where firms don’t possess exclusively any resource but try to coexist with the others.

The world is home to an estimated 11.1 million game developers, and this number continues to grow annually. The skills demanded of these professionals are constantly evolving due to the emergence of new platforms, the diversification of game genres, and the rapid advancement of technology. While some areas require highly specialized knowledge that drives the IT industry, the advent of sophisticated development tools has made it possible for even complete novices to create popular games, and those who utilize these tools can also thrive as accomplished developers. Our laboratory analyzes these shifts in the skills required of video game developers and their future prospects by investigating and analyzing global video game market trends and the progress of digital technology.

Simultaneously, by surveying the current situations and challenges faced by developers both in Japan and abroad, we delve into strategies for sustainable corporate growth in the rapidly changing game industry and the ideal approaches to human resource development within this context.

One of my research interests is the visual representation of relationships between observed variables. Graph modeling based on graph theory is used for this purpose. I and my collaborators have proposed a method of statistical computation using graph structures.

The other interest is the statistical analysis with missing data. In particular, my work is to develop statistical computation methods using the EM algorithm and Markov chain Monte Carlo. I am studying the acceleration of convergence of the EM algorithm and its application to statistical models.

CRM was developed by the laboratory of Yamaguchi is integrated in one database each company on another system decentralized information systems. Here, provides accurate customer information gathering, analysis and sharing. In addition, employees are working, you can take advantage of the system are. Plays the role of generating added value as a result, information infrastructure.

From this company is important, rather than in a specific department or human resources to implement CRM, employees share information, leverage and produce value added customer in problem-solving, while proposals to. It is a new concept of companies that cannot deliver value, judging by the value proposed by the companies using customer.

Now that Covid19 has settled down, the diversification of inbound customers will progress. Japan’s tourist areas will be required to be tourist areas that respond to diverse values such as religious diversity such as Halal, veganism, and LGBTQ. It means that each tourist area is required to select the value that is sought and to work on regional development that makes use of the strengths of the area.
Tourism has a broad base and a huge and growing market all over the world. In addition, it is an attractive industry that can realize tourism that benefits all people involved in tourism, including the industry, the business operators, and tourists.
I am interested in researching ways to help realize such a tourist area.

I am researching regional revitalization through sports tourism at facilities that utilize local natural capital and public goods. The area has capital that can be used as sports facilities such as sea, hills, rivers, waterfalls, earth lakes, parks, and roads. There are many in Okayama! In addition to large-scale facilities such as stadiums and arenas, we are working to create a playground by utilizing these regional capitals and to attract tourists from cities and overseas to the region.

In today’s highly complex society, it is difficult to realize the value that each seeks without transcending the traditional boundaries between the public and private sectors, or between providers and consumers, and integrating each other’s resources. In this laboratory, we are conducting research on the ideas and methods of service design that enable to cross boundaries from conventional standpoints, and on the possibility of co-creating new value through their utilization. We are aiming for practical research that overcomes barriers that hinder the revitalization of organizations and regions, such as diffused hotels that renovate vacant houses and stores into lodging facilities and transform entire town into hotels.

Let me introduce the second topic of my research interests:
Consider a situation in which we wish to select items or variables so as to delete the redundant variables or to make a small dimensional rating scale to measure latent traits, variable selection in principal component analysis (PCA) is necessary to identify a subset of variables that represents all variables as much as possible.
In the figure below, the left-hand plot is a scatter plot of the 1st and 2nd principal components (PCs) obtained based on all 19 original variables, and the right-hand plot is based on seven selected variables. Little difference exists between the two configurations of PCs. This illustrates the meaningfulness of variable selection in PCA since selected variables can provide almost the same result as the original variables if the goal of the analysis is to observe the configuration of the PCs.

We can perform the variable selection in PCA as a prior analysis in big data analysis, and apply the proposed selection procedures to other multivariate methods such as factor analysis and correspondence analysis.In this topic, we also study on how to deal with categorical/qualitative data (for the first topic), and how to improve the computation effectively (for the third topic).

In sports, which continue to evolve with the development of technology, the focus on sports analytics is increasing year by year, and at the same time, we often see sports analysts with such skills in action. On the other hand, there are still many issues regarding the effective use of data and technology.
In sports analytics, there are two types of information that can be used as weapons: subjective information obtained from experience, intuition, and human relationships, and highly objective information using video and data. Based on this idea, I am working on research to solve problems in the field of sports analytics using data science.

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.

In Japan, Eigyo is often confused with sales and treated as a subordinate concept of marketing. However, in reality, Eigyo in a company plays a broad role in “connecting” the company with its customers, each department within the company, each department within the customer’s company, partner companies, domestic and overseas, and even society. Our research focuses on Eigyo as a process of business transformation and social problem solving, rather than simply selling products and services, and as a value-creating entity.
