Seems like some of the Euro porn sites sell Jap dvds as well. I used to have a favorites list full of places to buy all kinds of porn. Finding the non pixelated stuff from Japan is a little more difficult but it can be done.

Here's one of my favorite vintage Euro stars Anita Rinaldi. She was in a really good movie with Rocco Siffreddi [the Bodyguard, Il Guardini?] I think as well as being a director later in her career.
