I am an Associate Professor at Kyushu University and Principal Investigator of the Itoshima Felix Study (IFS), a cohort study on frailty and well-being. I hold two PhDs, in Human Environment Studies (2010) and Medicine (2017). My research focuses on health promotion and preventive medicine for human well-being, particularly the role of physical activity and muscle function in preventing long-term care needs and supporting healthy longevity among community-dwelling older adults.
