Good Japanese Filem for a High school film fest? Please read description!!

I'm in the French club at my school and we want to do an international film festival at our school along with all the other language/culture clubs. We want to try and get as many different languages as possible into the film fest, since I've already seen a number of Japanese Filem I volunteered to find one to bring one in. The only problem is that after looking at them I realized the movie I had in mind is rated R so I can't bring it. So I'm asking anda guys if anda have any suggestions for good Filem I could show.

PLEASE READ

1) Filem can at MOST be rated PG-13, since it's a school, can't be Never Rated (NR) atau Unrated (UR) either, must have a rating.

2) BEFORE ANYONE SAYS STUDIO GHIBLI yes I Cinta them too, and yes I know they all have a suitable rating, the thing is, there are A LOT of people at my school who like anime, as a result A LOT of people have seen MOST IF NOT ALL of them, so I'd like to find a lebih original movie to show, if I did decide to do Ghilbi I'd pick one that's not as well known, either way, PLEASE DO NOT SUGGEST GHILBI

3) People need to be able to just watch it, so no Filem that are like continuations of an Anime series atau anything like that, has to be a stand alone movie.

4) It doesn't need to be animated, I know this is the Anime club but if anda happen to know a live action Japanese movie that fits the criteria stated above, sejak all means suggest it.

Thank You~
