Academic Activities
1.  In July 2012 an accused person in forties with the developmental disorder who has been charged with his sister's murder was sentenced to 20 years imprisonment by the Osaka district court. This sentence attracted public attention. The following are the reason for this: (1) the court that gave this sentence of the hardest imprisonment with definite term was "Saibanin-Saiban", in which 6 lay judges with 3 career judges not only announce findings but also decide sentencing in the case. (2) This judgment went 4 years over the penalty demanded by the prosecutor. (3) This judgment was based on the understandings that there are few institutions in the society for the treatment of the ex-convict with the developmental disorder and therefore early release from a prison is not good for the prevention of second offenses.
 This sentence reflects the characteristics of the japanese criminal justice system. Firstly also in the case of the developmental disorder the japanese criminal courts judge the responsibility capacity according to the framework made for the schizophrenia. Secondly in japan there is no system like as presentence reports. Therefore not all sentencing are based on the enough information about defendants, for example a living situation, developmental history and social capitals around her or him. Finally besides, in the "Saibanin-Saiban" carrier judges regard speed of the trial as important, so that professional opinions are not heard in courts often.
Japanese criminal justice system has the basic structure to give a defendant with the developmental disorder social stigmas easily. .
