Research Focus: The socio-political history of knowledge in modern and contemporary Japan. I am engaged in examining the characteristics of biomedical sciences, such as eugenics and the temperance movement, while also analyzing thought, media, social movements, and their impact on administration. Additionally, I am working on detailed analyses of media and regional history.
