With Abbas Kiarostami and Aki Kaurismäki, Kiyoshi Kurosawa is one of these "K directors" who signed a major work of contemporary cinema.
Raised by the Z series from Japanese studios, he's mostly haunted by unhappy ghosts, the end of the world and doors between levels of reality.
Before Jellyfish - アカルイミライ (teenagers developed a strange obsession for the fascinating animal, seen as a vague threat), Kurosawa signed a few masterpieces like Charisma (can a tree be a murderer?), Cure (hypnosis as a lethal weapon) and mostly Kaïro, which narrates how some troubled ghosts come through the Internet cable and spray bodies like an atomic blast, leaving just a shadow on the wall.
Later, Kurosawa entered the "real life" with elegance and subtlety with Tokyo Sonata and the diptych Shokuzai, but has recently gone back to his favorite subjects–with less inventiveness, which may happen to the best.
