Kuji-in or kuji-kiri is not practiced by *any* Japanese Buddhist schools, as far as I'm aware at least. I spoke with a Koyasan monk about it, and he said that Kuji-in is strictly onmyoudou or Shintoist and not related to (Koyasan Shingon) Buddhism in any way. So yeah. In "Ghost Hunt", Takigawa chants the mantra of Fudo Myouou, who is a Buddhist fire deity, which has zero to do with the kuji-in.
