Niigata University of Health and Welfare

Major in Rehabilitation Sciences
Field of Speech, Language, and Hearing Sciences


In addition to conducting experimental research and clinical studies on the structures, functions and pathological conditions affecting the language and auditory systems, the Field of Speech, Language, and Hearing Sciences also aims at determining the scientifically and clinically closely related “eating” and “deglutition” functions, and the principles of higher brain functions. It involves interdisciplinary research on the disorders, mechanisms, evaluation, training, methods of treatment of those functions. By elucidating the mechanism of mutually associated disorders of various types, the Field of Speech, Language, and Hearing Sciences educates human resources capable of implementing effective treatments and support aimed at improving the QOL of people with disabilities in the language, hearing, deglutition and cognitive functions.


Development of human resources equipped with professional expertise and applied skills
We promote basic and practical research and clinical studies. Our goal is to train human resources with deeper knowledge and applied skills.
Practice of wide-scope research rooted in clinical studies
We are engaged in wide-scope and clinically-rooted research themes. Hence, our research is not only limited to language and hearing disabilities or to the evaluation of the dysfunction and training.
