"The Japanese PC games market doubled in size from 2018 to 2021.
Japan's PC gaming market has roughly doubled in three years, growing to nearly $896 million US between 2018 and 2021. The user base of active PC gamers has increased by 5 million from 2015 to 2021, with 4.5 million of those playing exclusively on PC—up more than 100% from 2015's 2.2 million PC-exclusive Japanese gamers."

That 4.5 million gamers are only ones that play exclusively on PC and doesnt include the ones that also play on PC+Console. Thats pretty big as i always thought PC was very niche in japan. I guess its no wonder PC's are getting so much Japanese games the last few years as of right now the is more gamers who play exclusively on Pc than PS5 and XBSeries consoles combined. And they say this number is only going to grow cause of a number of factors such "growing acceptance of foreign and indie games available cheaply on PC, much greater availability of Japan-made games on PC, and availability of popular Smartphone games at launch on PC" .
I can maybe see even Steamdeck doing very well in japan.
Valve even has their own Japanese mascot now and he/she is damn cute!
