Japanese journalist Shiori Itō’s harrowing film "Black Box Diaries" is first person journalism at its very best. It details her alleged 2015 sexual assault by prominent media executive Noriyuki Yamaguchi – a close associate of Prime Minister Shinzo Abe - and is credited with kick-starting the #MeToo movement in her home country.

Itō went public in 2017 with her memoir "Black Box" and an investigation into her own sexual assault followed by an attempt to prosecute the high-profile offender. It would become a landmark case that exposed Japan's (where the legal age of consent was 13 - raised to 16 in 2023) legal system as archaic compared to the modern judicial and societal standards demanded in the 21st century.
The film includes traumatic video diary entries entrusted to Itō's phone, courtroom footage, hidden and damning recordings highlighting police inaction and incompetence and shaky handheld and fast cut shots that give the documentary the feeling of a thriller – which, as it involves scandal, conspiracy and a very real threat to life, it actually is, but with the vital caveat that this belongs to the realm of non-fiction.
