In mammals, auditory organ is composed of two types of hair cells, inner and outer hair cells, and various supporting cells. In contrast to the clear anatomical diversity of hair cells and supporting cells in mammals, the auditory organs of non-mammals show a simple structure in which hair cells and supporting cells are arranged in a row. I’m studying the evolution of the mammalian auditory system from a comparative anatomical perspective. In addition, I’m studying the molecules that are expressed characteristically in various types of supporting cells in order to elucidate the roles of each type of supporting cell in mammals.

Food hygiene is expected to more important due to HACCP and export of meat and marine product.
Pneumonia is a common disease in feedlot, and Mycoplasma bovis may be involved. The bacteria occur such as pneumonia, mastitis, and arthritis. Endocarditis, which causes lesions in the heart, is occasionally observed at slaughterhouses (Fig). The researches of adhesive factors for vaccine development leads to a stable supply of meat product.
Enterohemorrhagic Escherichia coli (EHEC, STEC), Salmonella, Campylobacter,which are known to be food poisoning, are tested at the Meat Inspection Center. The study of food microbiology that have attracted attention in recent years, such as Clostridium perfringens and Listeria monocytogenes, makes to improve food safety.

Non-human primates are prone to a variety of naturally occurring diseases, including diabetes, hyperlipidemia, heart disease, endometriosis, gastrointestinal disorders such as gastric dilatation and intractable diarrhea, macular degeneration, cataracts, periodontal disease, growth disorders, and tumors. We are conducting research to clinically and pathologically evaluate these conditions and assess their potential as models for human diseases.
Furthermore, chronic pain, such as neuropathic pain, can persist even after damage to the nervous system has healed, resulting in ongoing pain and discomfort. However, many aspects of its causes remain unclear. We conduct research on the assessment and treatment of chronic pain and visceral pain, with the aim of contributing to pain management in both animals and humans.
When I actually tried using toys to care for experimental animals, the animals often lost interest quickly and stopped playing, broke the toys, or left them in unsanitary conditions, which frequently led me to question their effectiveness. I am eager to actively engage in research on environmental enrichment for animals.

(Research on Campylobacter Control in Poultry Meat)
This study examines hygiene management for raw poultry dishes such as torisashi and tori-tataki, aiming to reduce Campylobacter food poisoning associated with undercooked chicken.
(Research on Campylobacter Typing Methods)
The project focuses on developing rapid typing techniques using bacterial genes, proteins, and other markers to support quick identification during outbreaks.
(Research on Risk Communication for Raw Meat Consumption)
This research explores effective ways to communicate foodborne illness risks related to raw meat products such as basashi, yukhoe, and raw liver, seeking new communication approaches beyond traditional one-way messaging.
(Research on Wildlife Management in Ehime Prefecture)
This study contributes to addressing agricultural damage and ecological disruption caused by wild boar, sika deer, and macaques through scientific analysis and collaboration among industry, government, academia, and financial sectors.

We are conducting research to return the relationship between both animals and humans to a more natural state by using low and high frequencies to deter roadkill and railkill as well as beast damage control. The low-frequency “InoDon kumaDon” uses sensors to drive away wild boars, bears, etc. trapped there, and the high-frequency “Hyper Deer Sonic” uses a timer to run for a certain time and is used on deer, birds, etc., with great results. There is no effect on other animals or humans. The high-frequency type is available in vehicle-mounted and installed types, while the low-frequency type is only available in the installed type due to the large diameter of the speaker. However, a portable type, Hyper Deer Sonic, is currently under development and is highly anticipated by people in the forestry and mountaineering industries.

We aim to contribute to the development of the wine industries and education, through our research.
Research and invstigation into wine, Japanese sake, fruits and functional foods. Invesigation of volatile compaounds in wine and its produvtion mechanisms. Especially, advanced analysis and evaluation of wine.Wine has favorable and characteristic flavor. We indentify the characteristic compounds in wine and investigate their production mechanisms.
Wine have multiple health functionalities since it is a fermented material. We investigate the health functionality of wine and fermented foods in vitro.And, we investigate the health functinalities of functinal components fermented foods.

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.
