There's several fantastic Japanese sites out there, check out the links page off BatLab's site and ISO's page. And it's fun to find your way around too, also check out some of the French Poser sites out there. Used to be a few German sites but I don't see them around anymore. Not a Japanese site but also check out the Japanese Room set in RDNA's free stuff (I think it's still available..) It was one of their very first free offerings long, long, long time ago.
