The opening 30 minutes of the film is simply a recap of the first film Ju-on (2000).
The oft-repeated claim that this movie was a direct-to-video release is false. Its world premiere was at the Box Higashi-Nakano theater in Higashi-Nakano, Nakano-ku, Tokyo, on Saturday 25 March, 2000. It played there for seven consecutive nights.
If you pause the movie 2 minutes and 54 seconds into it, look at the tree outside of the house, relax your eyes and look at it, you'll see a demonic looking face with eyes, nose and a grin on the top part under the very top spiked tree things, almost looks as if the demon has a spiked mohawk.
