I need my dose of SCARY!!!
 

Summer here is about to end. ( i don't know about your respective countries. but anyway)

I still am not satisfied with my read of horror stories!!!

Could someone please recommend some Japanese horror films/ shows????:D

If there was a post like this earlier, I'm sorry I haven't raed those yet!!! Sorry!!!

Jigoku Shojo is a good horror anime, I wouldn't say it was incredibly scary but then what animes are? The Ring and The Grudge are very good Japanese horror films, and although One Missed Call takes a while to get going it's one of the best and scariest horrors in my opinion. The Ghost is good too, but it's Korean and not Japanese :P

Tokyo Gore Police

This movie is not meant to be scary, though it depends a lot if you find funny or gross the gore. If you do find gross the gore then this will scare you.

Noroi

Edit.
Sorry I just notice you have 14 years old, I wouldn't recommend Tokyo Gore Police at all, is totally not suited for your age even for older people could be very difficult to watch for its grotesque content.

Audition too, it has some painful scenes.

Noroi, well I guess this one is okay, I would compare it with the Ring and some Blair Witch Proyect.

Tokyo Gore Police is nowhere near horror... :\

It's up there with Machine Girl in gormedy. (gore+comedy)

As for scariness, I'd suggest something along the lines of Re-Cycle. It's not Japanese, but it is an Asian horror film nonetheless.

If you wanna look at the trailer.
