History of Japanese psychopathology: Portraits of the second-generation psychopathologists (Takeo Doi, Yomishi Kasahara, Hiroshi Yasunaga, Tadao Miyamoto, Bin Kimura, and Hisao Nakai) and their relationship to psychiatric reform movement in Japan.

This paper attempts to provide an overview of the history of Japanese psychopathology by presenting concise portraits of the second generation of Japanese psychopathologists, whose era is considered to be the heyday of Japanese psychopathology. Meanwhile, we also consider the historical background of the psychiatric reform movement in Japan that influenced many second-generation psychopathologists. First, the paper briefly discusses the emergence of the first-generation of psychopathologists through the adoption of German-centered psychiatry after the Meiji era. In general, the first-generation can be said to have laid the foundation for the independent development of psychopathology in Japan. Then came the second generation, at a time when the psychiatric reform movement was gaining momentum, with the Academic Chair System of the Faculty of Medicine () heavily criticized, and psychiatric research itself halted temporarily. In order to continue the hampered academic research, workshops on "Psychopathology of Schizophrenia" were organized by the second-generation psychopathologists, whose major figures include Takeo Doi, Yomishi Kasahara, Hiroshi Yasunaga, Tadao Miyamoto, Bin Kimura, and Hisao Nakai. The invaluable contributions of the second-generation psychopathologists are essential to the development of Japanese psychopathology, and their close relationship with the psychiatric reform movement is worth reexamining, as it could be argued that the political tensions generated by the movement were the driving force behind their high-quality work.
