Research approaches and questions (RQs) for physical education teacher education research were organized to obtain basic materials for the future development of physical education teacher research in Japan. Furthermore, the possibility of mixed-method research (MMR) is examined from the perspective of research methods in the same field. The results show many previous studies where (1) RQs are not clearly shown as a problem of research methods in physical education teacher education research in Japan and (2) there is a problem in the methods of research design of MMR that compensate for the shortcomings of qualitative and quantitative approaches. Therefore, the further development of MMR, which emphasizes the research design based on RQs, is important for Japan’s physical education teacher research, where there are challenges in clearly describing the sequence of “RQ‒research objective‒research method.”
