Japanese prosecutors find themselves in the dock for abuses of power involving a number of high profile cases that have drawn considerable media attention in recent years. More than ever, the Japanese public is aware of the extent of prosecutors' power and how this jeopardizes justice. Until recently, prosecutors' post-WWII public reputation was relatively positive, and they were widely viewed as paragons of trust and propriety who had largely overcome the negative images stemming from their wartime role as tools of state oppression against critics and dissidents. This does not mean that Japan's procuracy has lacked critics both at home and abroad, but only recently has the positive public image come under sustained fire. The media is drawing unprecedented public attention to the ways and means of prosecutors and detailing their resort to unscrupulous methods in order to maintain their chilling 99% conviction rate.

6 This 23 day detention breaks down as follows: within twenty-four hours of detention prosecutors must ask a judge to approve up to ten days of additional detention beyond the initial seventy-two hours that any suspect may be detained at the police or prosecutor's discretion, and this detention may be extended for an additional ten days.

10 Weber, op.cit., p.8. The lay judge system that includes citizen judges and professional judges was introduced in Japan in 2009, chiefly as a way for the judiciary to regain public trust and respond to social changes in Japan. It is important to bear in mind that lay judges participate only in the first, lower-court trials involving crimes for which the penalty upon conviction is death, life imprisonment or imprisonment for a fixed term, or crimes in which the perpetrators' deliberate acts cause someone's death, including murder, acts of arson and dangerous driving.

21 According to media reports, the use of wiretapping has expanded considerably since then. In 2010, 47 people were arrested based on evidence gathered from eavesdropping and the number of warrants issued by courts, 34, was the highest since the law came into effect. Cases in 2010 included drug smuggling, a gangland murder and gun possession. Under the law, wiretapping is limited to illegal guns, gun possession, human smuggling and gang-related murder, not typical white collar crimes.
