At the Sakamoto Laboratory, our central theme is “Multilayered Scientific Exploration of Health.” We approach health from multiple perspectives—physical, psychological, social, and educational. While our foundation lies in basic medical science, our research extends beyond its traditional boundaries. We take an interdisciplinary approach that encompasses the mind–body relationship, effective educational practices, and human connections within local communities, aiming to understand health in a comprehensive and integrative manner.
—Histological Anatomy and Immunology in Lifestyle-Related Diseases—
We study how diet and lifestyle habits influence immune responses within the body. For example, our research examines how a high-fat diet (60% kcal from fat) alters the structural organization of the intestine and spleen, as well as how it affects the distribution and expression of immune cells and related proteins. Using morphological and immunohistochemical approaches, we aim to elucidate the mechanisms by which lifestyle factors impact tissue structure and immune function.
—Studies Using Epidemiological and Questionnaire-Based Methods—
This research focuses on the prevention of illness and injury. Several themes are explored, including studies on the relationships between social connectedness, happiness, and health among people living in communities and workplaces; investigations into psychological stress and health risks associated with workplace environments; and research on mental health among athletes. Through these studies, we aim to identify social and psychological factors that contribute to the promotion of health and the prevention of disease.
—Practice in Educational Evaluation and Critical Comparative Education—
Our research explores how university students enhance their motivation and collaborate with peers in the learning process. Drawing on Self-Determination Theory, we examine what kinds of support are necessary to foster autonomous learning. In addition, we develop and validate evaluation rubrics that facilitate self-directed learning, and we aim to systematize the educational value of “learning itself” through practical and reflective approaches to teaching and assessment.
