I've been working in Japan as a product manager/engineer for a few years. The market is indeed quite different from other parts of the world. It's hard to build trust and get sales in Japan, but once you do, your customers tend to stick with you for a very long time (sometimes decades or even longer - not in IT of course). Simply localizing your app is far from enough. You'll need a sales team, preferably composed of Japanese people, based in Japan. And you'll need to be patient.
