This book presents a comprehensive account of past and present efforts to introduce the jury system in Japan. Four legal reforms are documented and assessed: the implementation of the bureaucratic and all-judge special jury systems in the 1870s, the introduction of the all-layperson jury in the late 1920s, the transplantation of the Anglo-American-style jury system to Okinawa under the U.S. Occupation, and the implementation of the mixed-court lay judge (saiban'in) system in 2009.
