Towards the beginning when Kobayashi first went into the house and is looking outside and you can see Kayako moving out for just a moment before it cuts to black.
When Kayako is crawling down the stairs towards Kobayashi - that was so terrifying, dude! I found myself trying to push myself away from the screen. It was kinda an odd scene, though, in that once she did get down and was hovering above his head and murmured his name, I suddenly found myself feeling bad for her rather than afraid. Heh.
When the brother and sister go into the house at the end and (my memory's kinda fuzzy) at some point before she goes into the eerie room, she sees Kayako and Kayako's arms are abnormally long. Creepy.

The part with Kanna and the gaping hole where her jaw used to be would have scared me more if it looked more realistic. The computer effects are just too obvious, to the point of almost being laughable. But it was still a creepy scene.
I'd say the scariest part of this movie was probably Yuki's death. Just seeing Kayako's dark shape coming up to Yuki in the attic and seeing her there just inches from Yuki's face and knowing what's gonna happen, that's pretty creepy.
The Mizuho scene was pretty scary too.
No disrespect intended, sir, but shove it up your ass!

The Jaw scene really killed me when I first saw it. The suspense was very well crafted and the slow reveal of her mutilation. When Kanna looks towards you, that was the worst part.

The part that absolutely shocked me was the "your wife had a baby it's a girl" scene (I really didn't see that coming and it was pretty disturbing).
Yeah, that part was really scary! Seeing Takeo like, hit the baby, on the phone booth. Oh my god, I wanna throw up! That scene was pretty scary.

The part that absolutely shocked me was the "your wife had a baby it's a girl" scene (I really didn't see that coming and it was pretty disturbing). The stair scene, of course, was creepy as well as Kana's descent up the stairs and the reveal to her mother.
"You're a woman, Harry"

-"And I have an issue with staring, and Kayako was staring at Rika the ENTIRE stair scene, and the music wasn't helping."
That was Juon: the grudge(the 2003 movie).
The stairs scene in the original 2000 Juon flick is pretty scary too.

I was freaking out SOOOO bad during the stair scene. My heart was pounding and I was literally sweating, and right after that scene some car honked outside and I jumped like a mile.
Wow, once of the scariest scenes of a movie I have ever seen.
And I have an issue with staring, and Kayako was staring at Rika the ENTIRE stair scene, and the music wasn't helping. I'm like, omg I need to fast-forward, and then I didn't because I don't want to be a wimp, and I was watching it on my computer so she was really close to my face! ahhh!!

This is such a beautifully crafted horror movie. When I tell people about it, I say, "I would rather show a kid The Exorcist." It is truly the scariest movie I have ever seen. Cheap scares or pointless gore, while fun, can not bring the horror this movie instills on the viewer. Scary moments in movies bring a tear to my eyethis movie has tears rolling down my face: it never lets up.
The stair scene is fantastic. Toshio and Kana have to have some of the creepiest faces in the history of horror films. I've never felt such dread from someone simply opening their eyes. I just love it.
If you like this movie and you like video games, check out the Fatal Frame series because it is very reminiscent of this movie.

the moment where the guy finds the ghostly boy in the house, asks hims questions then the camera pans back and suddenly in the silence the boy makes that terribly un-natural cat-like sound.
That scene made me jump.
the bit when u see kaana walk up the stairs with blood all over her and you see her jaw missing.
Very creepy.
Also, The scene at the ending with Nobuyki. Damn was that very creepy. I gave the movie a 8/10.

OK guys, since most of you don't know the difference, I thought I'd bring it up again.
THIS IS JU-ON, THE V-CINEMA VERSION RELEASED IN 2000. WHAT YOU GUYS ARE THINKING OF IS THE 2003 THEATER VERSION ENTITLED JU-ON: THE GRUDGE. IT EVEN SAYS IN THE SUBTITLES OF THE 2003 THEATER VERSION.

Besides the stair scene, the scene where the tv news reporter gets all distorted and starts that throat clicking sound really freaked me out.
