The Department of Psychiatry was established in September 1902. From then onward, our Department has continued to play an important role as a clinical research center for psychiatry in Japan, in particular, in the fields of psychopathology, neuropsychology, neuropathology, epileptology, child and forensic psychiatry. We will uphold this tradition as well as applying newly emerging techniques such as neuroimaging, we aim to be a clinical, research, and educational center of psychiatry with the best quality.

Research and Education

By applying neurobiological as well as psychosocial approaches flexibly, we aim to achieve a multi-faceted understanding of psychiatric disorders. Using high-resolutional MRI, The Neuroimaging Group is attempting to elucidate the neural correlates of various neuropsychiatric conditions. The Psychopathology Group mainly focuses on eating disorders, dissociative disorders, psychiatric issues of epilepsy, as well as psychological aspects of recipients and donors of living organ transplantation. In collaboration with brain surgeons and occupational and speech therapists, the Neuropsychology Group is investigating neural correlates of cognitive and behavioral sequelae after brain damage. The Child and Adolescent Psychiatry Group is currently focusing on developing diagnostic assessment tools, relationships between phenotypes and neurocognitive functions, as well as effectiveness of various interventions. The Forensic Psychiatry Group tackles issues of criminal responsibility and civil competency of individuals with mental disorders. Collaborations among these groups are very active, and, as a result, our Department remains to be a best clinical, research, and educational center of psychiatry.
