The Suicide Song is a Japanese horror movie written and directed by Masato Harada. It was released by Shochiku in Japan on August 25, 2007.
The film’s story begins when a teenage girl named Kana (Atsuko Maeda) inexplicably commits suicide at her high school while humming a strange song.
Rumors start to fly around the school that her death was actually caused by a mysterious song, further perpetuated by the editor of a tabloid magazine named Riku (Ryuhei Matsuda).
More suicides occur after this until Kana’s friend Anzu (Yuko Oshima) finally unravels the mystery of the curse, as well as the song’s true meaning.
