I'm kind of burned out on the Japanese horror movies, inevitably they all center around the same plot. Something happens to someone because of some dead ghost person, then possibly happens to many more people after that in a similar fashion until the end of the movie, at which point there may or may not be a sequel.
You can see this same plot in Dark Water, One Missed Call, Ring, Kairo, and Juon---
I like Miike's films, but some of them are a little too violent for my tastes, (Audition, Koroshiya 1, Izu)---
I used to watch a lot of these movies, but these days I prefer something more lighthearted where a corpse isn't being dragged down into a well---
For horror, I'd recomend Three Extremes, three short films, and they are all fantastic and freshly done. Also, the Korean movie, R-Point.
