Since the 1st (actually 4th) of january 2015, 222 japanese visual novels were released for Windows.
Most of them are even exclusives !
I just thought it was a fun fact worth sharing, as microsoft and japan aren't usually bring in the same sentence, and when people talk about japanese games they mostly think about consoles and mobile.
