I don't think her fanbase outside of Japan increases her popularity as a whole. I don't have any statistics on that, but I'm guessing her fanbase outside of Japan has remained relatively constant, with minimal growth if any. And even if it did grow, it would just be offset by the fans she has lost in Japan/rest of the world.
