If you loved I, the Executioner, try The Tale of Oiwa's Ghost
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 Tai Katō, and they both carry the dread, foreign gem mood tags, and they sit in Drama / Horror territory. If that's the register that drew you to I, the Executioner, the second film will land in a comparable space — through a different lens.

What The Tale of Oiwa's Ghost is
Edo. A paper lantern. A disfigured woman begs for justice. Her husband's treachery exposed, a vengeful spirit rises. Poison plots, dishonor, and a thirst for retribution plague the guilty. A classic ghost story, rendered with a stark fatalism typical of '60s Japanese horror.
