And they haven't even released a lot of big games yet. Imagine when they start hitting.
This is actually what's a bit worrying, because they have been releasing some of those games by now. Final Fantasy XVI and Armored Core 6 were probably two of the biggest releases for the Japanese market so far, but they don't seem to have the long-term tail in sales for Japan the way a lot of Nintendo's games do.
Which I guess points to another issue: the only games that are constant big performers with long legs in Japan are Nintendo's own tentpole IPs. Even quite a few 3P releases on Switch don't move massive numbers in Japan, despite the install base size. And, PS5 is a much more digital-oriented platform than the Switch, that's true.
Without much in the way of digital sales data though, we only have the physical charts to go by and the biggest releases do physical numbers that would look modest or even low-performing if they were on the Switch, in terms of being compared to the big releases from Nintendo on that system in Japan. Hopefully the digital is making up the difference on PS5 in that region, or maybe people are really just using it as a F2P system for Geshin Impact and stuff like that.
I think it's a valid question to bring up, without downplaying the console's success in Japan hardware-wise because it indeed is outpacing PS2 & PS3 (and PS4) there. Something a lot of haters and naysayers were trying to imply was impossible.
