Rio has been in the JAV business since 2006 at the ripe age of 18. She went from pumping gas at a service station to getting pumped on film. And in a short but seriously busy time the list of her DVDs is just outlandish. Seriously a look at her Wikipage and you have to scroll through the list of her DVDs and everything else for some time before you hit the bottom. I'm not even going to bother counting them because of that. She has actually worked under several different names during her short career time including her several picture sets from online websites. So it's actually not all that easy to track down everything she's done.

Anyways lets get to those pictures and videos which is of course what you're here for anyways.
Scanlover Forum -- Oh yeah there are some good links there Her picture thread, discussion thread and oh hey what's this an animated gif thread. Oh yes. Do understand though while looking at her pictures she is naked a lot.
AVexp -- has four sets of pictures to check out.
Some dude's personal blog with lots of links to stuff. Rio Hamasaki
Another one of her personal blogs -- Rio Hamasaki
Your best bet for finding more pictures of her is of course google image search (just remember to turn off safe search) which turns up a lot of stuff in the hidden reaches of the internet and I'm just to lazy to link to them all.
On the other hand videos are pretty easy to come by when it comes to Dailymotion and there are some very naughty videos on Dailymotion compared to YouTube.
