BLACK BOX DIARIES follows director and journalist Shiori Ito’s courageous investigation of her own sexual assault in an improbable attempt to prosecute her high-profile offender. Unfolding like a thriller and combining secret investigative recordings, vérité shooting and emotional first-person video, Shiori's quest becomes a landmark case in Japan, exposing the country’s desperately outdated judicial and societal systems.

Shiori Ito is a journalist, writer, and documentary filmmaker. Her primary focus is gender-based human rights issues. She co-founded Hanashi Films, a Tokyo and London-based production company that has collaborated with NHK, BBC, and Al Jazeera, among others. In 2017, Shiori wrote the book “Black Box,” based on her own experience of rape. The book reveals the sexism in Japan’s society and institutions, and won the Free Press Association of Japan Award for Best Journalism in 2018. It has been translated into a number of languages. In 2020 she was listed as one of the 100 most influential people in the world by Time magazine. BLACK BOX DIARIES is her feature documentary debut.
