Research summary
Study for establishing estimation-method and standard laboratory procedure of forensic sciences 　While the role of forensic　sciences has increased in court, errors of forensic tests occur misjudgment in some cases. In 2013, the Supreme Court Judicial Training Institute examined the reliability and probative values of forensic tests, and pointed out the need to unify and improve the quality of the forensic test method ("Path forward for Scientific evidence and trials using this", hereinafter referred to as “path forward "). 　The purpose of this research is to (1) quantitatively evaluate the reliability of forensic tests through the verification of scientific evidence in past retrial cases, and (2) develop guidelines that set forth the criteria for forensic tests. Specifically, estimation-method for reliability, standard laboratory procedure, and terms of forensic tests will be established. This can be leads to improvement of forensic laboratory procedure, and increasing the reliability of forensic tests, which can contribute to the prevention of misjudgment.

Message
1.	The purpose of this study is to highlight the problems based on my many years of forensic tests, improve the accuracy and reliability of forensic tests, and contribute to a fair trial. 　Unfortunately, Japanese forensic sciences lack conscience, honesty, transparency and independence as a science, and have not reached the level of forensic science in Europe and the United States. 　Japanese forensic science has to break away from the science that contributes to police investigations and be reborn as a science that contributes to justice.
