Hardware sales in Japan really look to me to be skewed because of a not insignificant amount of units going to China, PS5 baseline is way too high, even PS4 being way up over last year tells me a lot of systems (Switch too) are going to China because no one there wants to buy the Chinese systems (can't blame them).
Also lol, Pikmin 4 is going to outsell a mainline Final Fantasy game in Japan, who'd have imagined that 20 years ago.
