I don’t think it has a chance to increase. From what I’ve read over the internet it seems that Japanese retailers don’t want to sell Xbox at all. Especially the expensive one x. So they probably won’t even buy it from MS. So the sales can’t increase if console won’t sell at all in Japan.

Yeah and no, you can't buy xbox one x from the stores directly. You had/have to pre order one and then they would order one from MS that's why the stores are full with Xbox one X's sold out signs or like you mention we don't have Xbox one X because we don't want to pre order consoles signs:

"So yeah, while the Xbox One X did cause a significant boost in Xbox One sales percentage-wise, it’s obvious that it was shipped in very limited quantities, and the fact that major retailers did not carry any availability on day one certainly did not help sales either.

At this point, though, we can probably safely say that the promise of massive power (at least for a console) did not particularly tempt Japanese gamers."
