If you loved Reincarnation, try Ju-on: The Curse 2
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Takashi Shimizu, and they both carry the dread, slow burn mood tags, and they sit in Horror / Mystery territory. If that's the register that drew you to Reincarnation, the second film will land in a comparable space — through a different lens.

What Ju-on: The Curse 2 is
Tokyo suburb. Summer cicadas. Rotting porch swing. A realtor’s sibling enters a seemingly abandoned home at his request. A vengeful spirit marks her. J-horror at its finest.
