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.

There are good times and bad times in sports, so it is said that in the sports business, you should not think on the premise of “victory.” Of course, it’s good for the team to win a lot, but if you rely on it to do business, it’s easy to reduce the number of spectators and sales of goods when the team can’t win very much. Therefore, it is important to have fans who support the team. Those fans are absolutely indispensable when thinking about sports business.
Therefore, I think that if sports fans can clarify the characteristics, sports teams can do “strong management” regardless of their performance, so I research it every day.

We are researching the process by which organizations and teams develop and improve, approaching the topic from the perspectives of coaching, strategy, and psychology. We would like to clarify how winning (success) fosters individual motivation and team strength, which in turn leads to improved organizational strength, and focus on developing human resources who can contribute to society. In recent years, there has been a growing trend to use sports in corporate training as an opportunity to learn about organizational management and coaching. This is based on the idea that the processes by which sports teams and companies develop as organizations are similar, and is attracting attention as a method for learning about “organizational management.” The fields of management and coaching methods are also changing due to the diversification of work styles and the spread of social media. We are also conducting research with a view to researching how to create organizations that can effectively develop human resources.

Graph representation methods are very useful for data analysis. Our research focuses on devising and developing new visualization methods to visually represent the characteristics of multivariate data and the characteristics of clusters.For example, we have proposed and developed expanded constellation graphs based on the concept of constellation graphs, and have examined its usefulness.
The figure below shows the flavor characteristics evaluated by applying the expanded constellation graph to the flavor data of Scotch whiskey. The graph shows that each cluster is clearly classified. In addition, the lines (paths) show the characteristics and trends of the data.

[Health promotion and lifelong sports]
The important thing is to keep exercising. Sports are also important from the perspective of release stress and mental health. Wearable devices have made it possible to measure heart rate and walking distance during exercise. I promote research that contributes to health promotion and lifelong sports.
[Choice reaction time and performance]
The study of choice tasks leads to improved sports performance. The study of reaction time improved prevent accidents. I am studying reaction time and selection tasks.
[Environmental temperature and physiological stress]
Physiological stress during exercise in a hot or cold environment is evaluated using indices such as heart rate and body temperature. I am studying against heatstroke and prevention of hypothermia.

Financial accounting is an accounting method that companies use to disclose information to the outside world. Since the information is disclosed to external stakeholders, which can be regarded as the company’s performance, the reliability of the information is very important. There are various mechanisms to ensure or enhance the reliability of financial information, and internal audits are one of them. So my research questions are “how do internal audits affect the quality of financial information?” and “what is the relationship between external and internal audits?”. I use statistical methods based on publicly available data from companies to answer those research questions.

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).

The effcts of chemical substances on living organism depend on animal species and developmental stage. A lot of unexplained subjects exist in these reserch topics. I tackle researches in order to clarify the pathogenesis of lesions induced by chemical substances in various aminal species, such as rat, quail, chicken, medaka and newt in different developmental stages.

We not only analyze the health status of humans, animals, the environment, and food, but also develop new testing methods to evaluate them.
In recent years, we have been conducting joint research with local governments and companies to develop processing methods to reduce food loss and add value to food ingredients, to evaluate the pharmacokinetics of functional ingredients in foods, and to develop new testing methods for inflammation markers.

Novel technologies to efficiently and safely disinfect agricultural products have been studied. We aim to contribute to food safety and security by developing innovative disinfection methods..

In addition, we have studied the effect of disinfectants against a range of pathogens on different materials, including influenza virus and feline calicivirus (a surrogate of human norovirus) as well as prions (most resistant pathogen). We also analyzed the likely mechanism of pathogen inactivation. Given our focus of research, we would like to collaborate with companies to assist in evaluating products as well as developing new technologies.

(1) I have been studying the prescriptive grammars compiled in the 18th century. I have especially focused on James Buchanan’s works, such as grammar books, dictionaries, and so on, who flourished in the middle of 18th century, in the terms of historical sociolinguistics. One of my main investigating points is that why prescriptive grammars were needed and how grammar books affected the then society and the education in the 18th century. I have also been studying the differences between the usages used by the 18th century authors and the ones in prescriptive grammars, analyzing Buchanan’s grammar books.
(2) I have been studying the contemporary English grammar and usages. Researching the large corpus data of the contemporary English, I have been surveying the differences between the grammar and usages in “school grammar,” that is, prescriptive grammar, and the real ones. The results from the survey have been applied on my teaching English in my classes.

The old cat gradually has decreased kidney function, and many cats often die for chronic kidney disease. Therefore, I can extend the expectation of life of the cat by detecting the decrease of the renal function on the earlier stage, and managing it. I focus on urinary a very small amount of protein excreted as a renal function marker of the earlier stage. I am going to establish simple and easy diagnostic procedure in the chronic kidney disease of the earlier stage by creating the recombinant protein of its marker, and making a monoclonal antibody, and establishing of measurement system. Furthermore, Hyperparathyreosis to be complicated for chronic kidney disease causes mineral metabolism abnormality. We find that parathyroid hormone is connected directly with various symptoms to appear for chronic kidney disease. Therefore I establish simple and easy early diagnostic method of hyperparathyreosis and research the method of use of various phosphate binders which are its therapeutic drug.
Also, in recent years calcium oxalate calculosis increases to a companion animal similar to humans. Therefore I research the mechanism that a calcium oxalate calculus is formed by all things (food, supplement etc) to ingest, and I research a method to inhibit the formation of the calcium oxalate calculus.

Mammalian immune system consists of innate and adaptive immunity. Innate immunity can broadly recognize invading pathogens through various pathogen sensors and responds rapidly. On the other hand, adaptive immunity is more specific and recognizes the peptide from antigens. An antigen presenting cell, dendritic cell, can link innate and adaptive immunity. Recently, it has been revealed that immune responses are involved in and affect various types of diseases including not only immune disorders like autoimmune diseases but also metabolic syndromes, diabetes, neurological disorders, cancer, and so on. I am analyzing immunological and pathological roles of innate immune system, including dendritic cells, in immune disorders and various diseases with genetically modified mice.

We study on the biological characteristics of fish parasites with the aim of disease control. Also, many fish parasites in seafoods have been subject to complaints by comsumers. However, fish parasites normally live in wild environments, and it is crucial to discriminate between harmful and harmless for humans.
To improve the quality of farmed fishes, we try to feed grape pomace, effluent from winemaking, on the immunity and health condition in cultured fishes.

Smooth muscle cells are major components of the organ walls of organs, such as artery, gastrointestinal tract, bladder and trachea. Smooth muscle cell motility is highly regulated by nerve and hormonal stimuli. Accumulating lines of evidence suggest that impaired smooth muscle motility is involved in a variety of diseases, such as hypertension, digestive dysfunction, asthma, and dysuria. To elucidate the molecular basis of smooth muscle diseases, and to develop their effective diagnostic and therapeutic strategies, we have been studying the mechanisms that regulate smooth muscle motor function. Meanwhile, we have discovered a protein that regulates smooth muscle contractile function and have elucidated the underlying mechanism by which the protein mediates regulation of smooth muscle motility. We now study the signals in smooth muscle disease.
In parallel with our research on smooth muscle disease, we are assisting in the development of devices and products to improve the quality of life of animals, including pets, and their owners through collaborative research.

It is generally understood that the microvascular system contains arterioles (afferent and resistant vessels), venules (efferent vessels), and capillaries (exchanger vessels). Now we recognize that microcirculation includes not only the microvascular machinery, but also interstitial space fluid dynamics and the lymphatic system. All of vertebrates have to circulate blood into each tissue-cell through the transport mechanisms to supply nutrients and remove wastes. The microcirculatory system is indeed a main player to regulate body fluid homeostasis, which maintains an internal environment of the body, indicating that macro-circulation (heart and large vasculatures) is a support system to pump blood perfusion. Thus, failure of the microcirculatory system evokes dysfunction of activity and survival in tissues-cells and subsequently determines life and death of creatures and humans. That’s why the microcirculation world has never been micro, but huge, space to integrate each cellular function and life support. We continue challenging to explore ‘bench to bedside research’, that is available for preventation, diagnosis, and treatment of diseases, through understanding heterogeneity and analyses in the regulation of microcirculatory functions among tissues-cells.

Among infectious diseases caused by pathogenic microorganisms such as viruses and bacteria, we are studying zoonoses, which are infectious diseases between animals and humans. In recent years, with the increasing distance between animals and humans and the improvement of diagnostic techniques for pathogenic microorganisms, it has become clear that a variety of zoonoses exist in the world and pose a significant threat to us and human society. Our research contributes to the prevention and control of these zoonotic diseases by clarifying how these pathogenic microorganisms are actually maintained in the field and the degree of risk they pose to humans and animals. We also conduct molecular biological studies using actual pathogens and various types of cultured cells to evaluate pathogenicity and elucidate the mechanisms of pathogen transmission.

Blood circulates in our body through various size of blood vessels. Since the blood flow rate is regulated by the vessel diameter, the constriction of the vessels affects the activities of organs. Based on this fact, I am investigating two different blood flow regulation. The first is skin blood flow. We are flushed with hot weather, pale in cold weather. Thus, skin blood flow depends on temperature, and this regulation is different from other vessels. Since reduction in blood flow exacerbates pain, I am investigating the relationship between onset of pain and decrease in blood flow. The second is hepatic blood flow. Hepatic stellate cells are attached to capillaries, so-called sinusoids, that form a network in the liver, and hepatic blood flow is thought that regulated by this cell. However, it is not well known that how the hepatic stellate cell regulates the blood flow. My second subject is to clarify this physiology. During hepatic injury, the hepatic stellate cell will be transdifferentiated to collagen producing cell, which exacerbate inflammation, advance liver fibrosis and impair blood flow. Controlling the transdifferentiation is also an important subject for controlling the regulation of hepatic blood flow.

Parasitic diseases caused by protozoa, helminths, and arthropods have long been recognized as threats to the health of humans and animals. “Parasitism” is defined as a symbiotic relationship between different species where one species (the parasite) benefits while the other species (the host) suffers harm. Although “symbiosis,” where both species benefit, is distinguished from parasitism, in reality, the boundary between parasitism and symbiosis is often blurred. In diverse environments, parasites and hosts interact with each other for survival, and they are also influenced by symbiotic microbiota. Parasitic diseases are a part of this interaction. I explore such complex host-parasite relationships to understand the pathogenesis of parasitic diseases.

When the tumor cells are beyond 42.5 degrees centigrade, the tumor cells become extinct rapidly. The radiofrequency waves gather to the tumor tissue efficiently, and only a tumor can heat. Because only an electromagnetic wave enters from the outside the body, we do not lower the quality of life of the patients. Figure is the abdominal CT image of the dog in which the large tumor rolled up an important blood vessel and widely occupied from abdominal to pelvis cavities. The surgical operation that only this tumor resected was very difficult, and oncothermia treatment (thermal treatment) was performed because owner did not want anticancer drug treatment. The volume of the tumor after about 2 months of oncothermia treatment became small as compared with that of the first day of treatment. Furthermore, the volume of the tumor reduced to about 1/8 after about 8 months of oncothermia treatment. The quality of life of the patient improved, too.
It is known that there is a cytoreductive effect synergistically when the thermal treatment combines with radiotherapy than use alone. My aim put the combination of radiotherapy and oncothermia treatment into practical use in the veterinary clinic.
