I’m not really surprised by this. It took so long for the PS5 to actually be available over here (it still can be hard to find some of them - the electronics store near me has base PS5s available, but the cheaper digital only one has been sold out for months) that people started getting PCs.

Sony wanted to focus on the western market, and now, well, a good chunk of the Jp market they took for granted is responding by getting PCs.

Based on what I’ve read, even though Valve had a real, public launch of the Steam Deck late last year, it didn’t particularly sell too well as the Japanese market found it a bit expensive. But that information was early this year so sales probably picked up since then.
