Trying to find this asian horror i saw in brisbane in 2003?

I was in Brisbane in 2003 and I was up late watching horror movies and there was an asian horror movie playing on one of the local channels. I really want to know what it was because I never got to see how it ended.

This is what I can remember from the part I did see, so if anyone remembers it and can help me out, I’d be super grateful?

I watched it on tv
It was in 2003 so pre-that year is most likely, it felt fairly recent so within 3-5 years possibly?
The male hero was a police detective or somehow related to the police (coroner maybe?)
The female character was some sort of ghost/demon/supernatural being who somehow came and went through water (I clearly remember a scene where she came out of an indoor pool?)
I think it might have been japanese but I could be wrong?
She was killing people for some reason? Which is probably why the police-dude was looking for her?
There was a bunch of people in a lab or building and she was killing them one-by-one and I think they cornered her in a room and she was trying to get back to the water but I think she died?

I just remember it was about water, and there was a lit pool at night, and not much else?

Sorry, I know that’s not much to go on, and I could be completely wrong about everything I just wrote, so pleeeease, suggest anything even vaguely similar? Or even stuff that isn’t similar, I’ll still check it out and something might spark a memory?

Thank you.

    1. Thank you so much for your suggestion, I have looked at both versions and this is not it, unfortunately.

      I did remember something else, at the end of the movie there was a fire in the building with the pool?

      1. Thank you so much for your suggestion. I have checked out both Ringu movies and unfortunately they aren’t the movie I remember.

        But I did remember something else that might help? At the end of the movie there was a fire in the building with the pool? And I sort of feel like the lady was made of water but could become a physical body? Could be wrong about that part tho 😉

Got something to say?
