We conduct a wide range of research and educational activities, mainly based on educational economics, including infant education, inclusive education, recurrent education, and employment of the elderly and disabled. In addition, we conduct research to meet the needs of society, focusing on the human services field, such as theoretical establishment of systems and policies related to QOL and rehabilitation medicine, as well as the development of scales.
