There was a promotion for the Xbox Series S in Japan. Those who purchased a Series S from June 13 to 25 got a free gift card worth 4,000 yen. That is why sales went up as much as it did for a few weeks last month.

I see forgot about that. I kinda find it funny because that 4000 yen is probably the amount Microsoft raised prices in Japan. So technically it just returned to its former price disguised as a good deal. 
Also do you have an idea why PS4 sales are increasing year to year? 

I don't really know the cause of the PS4 sales being up so much year-on-year. Other than maybe there being next to no stock a year ago and there now being stock available. Though, it does seem like Sony has discontinued the PS4 as they stopped giving shipment figures.
