In this article, the authors translated the chapter titled "History of Psychiatry in Taiwan During Japanese Imperial Period" in "Bulletin of 50th Anniversary National Taiwan University Hospital Department of Psychiatry", published by Department of Psychiatry, Medical School, National Taiwan University (NTU) in 1996, with adding some information and captions. NTU was initially founded as Taihoku Imperial University, the 7th Imperial University in 1928 during the Japan rule age. After World War II, it renamed as NTU. During the Taihoku Imperial University period, three prominent psychiatrists (Jyo Nakamura, Yawata Takeuchi and Shuzo Naka) had played a critical role in founding psychiatric hospitals and institutes in Taiwan, which heritage was handed down to the first Taiwanese psychiatric professor Tsung-yi Lin after the World War II. The bulletin recorded the details of the very beginning of psychiatry and teaching scenes in Taiwan during the Japan Imperial era. While there have been only a few reports by Japanese investigators, regarding the early history of psychiatry in Taiwan, it is of great value that this historical document of psychiatry was written by modern Taiwanese psychiatrists looking back on the Japan rule age.
