Japanese Indie Scene?

[TallSilhouette]

I was just thinking about indie game development around the world and realized that I can't think of many Japanese indie studios, especially compared to their prominence in the AA-AAA space. Do we hear less about them because they tend not to get localized for the West? Do they just concentrate more on mobile? Or is it that the Japanese indie scene really is just comparatively smaller than other parts of the world for some reason?

Also, what is your favorite Japanese indie developer?

Thanks.
