depends how stringently you define JRPG I guess. I personally wouldn't put Monster Hunter on the list because it has no leveling system outside of equipment and that to me makes it an Action-Adventure. On the other hand games like Demon's Souls and Disgaea 3 sold enough to make it on your list and I would call both of those JRPGs.
Also Atelier Rorona actually didn't do too bad. Sold 180k in the West which almost gets it on the list.
