Clinical practice and research activities for early psychiatric intervention at Japanese leading centres

To describe clinical practice and research activities for early psychiatric intervention in Japan, a country with a huge number of psychiatric beds and a history of long-stay, hospital-based psychiatry.

The characteristics, methods and activities of early intervention studies and implementation at four leading institutions in Japan are described.

The Tokyo Youth Club (Tokyo), the Department of Neuropsychiatry of Toyama University Hospital (Toyama), the Sendai At-risk Mental State and First Episode (SAFE) service (Sendai), and the Il Bosco of Toho University Omori Medical Center (Tokyo) have unique and active psychiatric programmes. Eachcentre has its own clinical research programme and treatment strategies. The Japanese Society for the Prevention of Psychiatric Disorders, founded in 1996, has made a steady contribution to psychiatric care by providing a forum for members to promote best practices for early intervention and by hosting annual meetings to discuss research and treatment.

The Japanese psychiatry service is continuing its transition from hospital-based psychiatry to community-based psychiatry. Despite these difficult circumstances, the publication of data on the duration of untreated psychosis in Japan along with evidence that early detection determines outcome has encouraged new attempts to promote early psychiatric intervention.
