title: Development of forensic mental health services in Japan: working towards the reintegration of offenders with mental disorders.
abstract: BACKGROUND
  Until the recent enactment of the Medical Treatment and Supervision Act (MTSA) in 2005, neither legislations nor facilities for mentally disordered offenders were available in Japan. The aim of the country's forensic mental health services, based on this new law, is to improve the social reintegration of mentally disordered offenders. In order to provide optimal psychiatric care to these individuals, specialised court proceedings, treatment facilities, and concrete guidelines have been established. The aim of this study was to review the current status of the new system and to clarify future challenges for improving services.
  
  
  METHODS
  The authors collected official statistics regarding the new system published separately by the Ministry of Health, Labour and Welfare, the Ministry of Justice, and the Supreme Court of Japan. We aggregated the data and examined the system's current implementation status, nationwide.
  
  
  RESULTS
  There were 2,750 requests for enrolment in the MTSA system between its initiation in 2005 and 31 December 2012. Of those requests, 2,724 cases had been concluded in court. In 63.1% of the cases, an inpatient treatment order had been made; 82.4% of those inpatients were diagnosed with schizophrenia. By the end of March 2012, two patients completing treatment under the MTSA had re-committed a serious offense. While overall designated inpatient and outpatient treatment facilities have reached national targets in terms of resources and beds available, a regional gap in MTSA designated facilities remains and the number of patients under inpatient treatment order is on the increase.
  
  
  CONCLUSIONS
  Overall, the MTSA system has been running smoothly without encountering any serious problems. However, several concerns have emerged, such as the accumulation of patients under inpatient treatment order and insufficient regional resources. To more successfully promote the reintegration of mentally disordered offenders, improvements in outpatient treatment and welfare services are crucial. In order to install effective measures to help improve the system, a nationwide database of patients being treated under order of the MTSA should be properly built and maintained.
