Dragonball (set when Son Goku was little and the comic wasn\'t just some tedious and never ending build up to a big fight) certainly includes nudity, but it\'s very minor and all done in a rather slapstick and comedy way. I suspect there is a bit in DBZ too. The situations are certainly not something you could get away with in many more conservative countries though, and I suspect they may have been cut out of UK and US versions (I picked mine up on holidays in France when I was younger)
There\'s this whole crazy plotline at the very start, where the young Goku is discovered by Bulma. They go to sleep but Goku wakes and decides to rest his head in Bulma\'s lap for some reason, and notices that she is rather flat down there. Having never seen a woman before and with no real social etiquette he slips off her panties to investigate and recoils in shock, screaming \"YOUR BALLS HAVE GONE!!\" Bulma (thinking that he means the Dragonballs) panics, sees that they are still there, and goes back to sleep.
The next day they meet Kamesennin and he offers to give them his Dragonball if Bulma shows him her panties (because he\'s a dirty old bugger). Bulma agrees and lifts up her skirt, not realising she is still not wearing any panties, and Kamesennin\'s nose erupts in a spurting and symbolic nosebleed!
Later Kamesennin\'s powers are required, but once again his randyness gets the better of him and he will only help if Bulma shows him her breasts. She\'s not willing to show him though so Oolon (a shapechanger) transforms into Bulma instead, and shows him her breasts, then offers him a little \'Paff paff\' and procedes to beat Kamesennin around the head with them, causing yet more nasal spurtage.
Sorry for the trip down geekdom lane and going so far off the initial topic it\'s criminal, but the memories all came flooding back.
It does illustrate one thing though, the Japanese are bloody mental. It\'s great!
