Can you guys recommend me some J-horror?

Question:

I like movies like the grudge where things pop up and something scary happens most of the time. Can you guys recommend something new, like what horror is popular in Japan up till now?

I watched:
The grudge
The ring
Scary Sunday series
suicide circle
the eye
red shoes (i think this is korean)
apartment 1303
one missed call

That's all I can think of right now. Oh and a movie about a train but i forgot what it's called.

Answer:

I'm pretty sure the suicide circle is korean also. but some other j horror movies are the Locker 1 and 2. they are pretty good.
