Mark Schilling Japan CorrespondentBack in Japan after his Korean-language drama “Broker” won two prizes at this year’s Cannes festival, Kore-eda Hirokazu appeared as a press event in Tokyo on Tuesday to announce the launch of a group of industry professionals who aim for structural reform of the Japanese film industry.The group calls itself the “Association for the Establishment of a Japanese Version of CNC.” The reference is to France’s government-backed oversight body, the Centre National du Cinema et de l’Image Animee. Kore-eda noted the low incomes and long working hours of freelance filmmakers and emphasized the need for reform.
