In March 2022, four actresses came forward with allegations that, beginning in 2011, Sakaki had coerced them into non-consensual sexual relationships.
Sakaki had admitted to having intercourse with three of the four women, claiming it was consensual; he denied having any kind of relationship with the fourth woman.
The victims allege that Kinoshita and Sakaki collaborated in sexual coercion by introducing young women to each other that were looking to break into the film industry.
