I'm just surprised that Galaxy is available in japanese. Maybe I'm wrong, but I thought PC gaming is just not a thing in Japan, other than maybe MMOs.
This has changed a bit over the last years. PC is still not the biggest market, but a few PC-only titles (MMOs iirc) have been pretty successful in Japan. That's also a reason why more Japanese console titles are ported to PC.
What I also find interesting is that a lot of "H" games which are exclusive to Japan are PC-only (some are now ported to VR consoles though), and a few of those are pretty demanding regarding hardware. So there must be a solid base of gamer PCs in Japan.
