You've been WAY behind on japan's opinion of PC games, it's easier now to count the games that don't receive a port than games that do, like Unicorn Overlord. I dreamed of having Persona and Like A Dragon on PC back then. Even the newest idolm@ster is on steam and people are making a translation for it.

Since it's just a massive headache for niche devs nowadays they are just skipping the Playstation version altogether, like the new Bunny Garden having only switch and PC versions.

Idk the last few years have been pretty good when it comes to PC ports of Japanese games IMO.

We got stuff like the RE remakes, good PC ports for japanese franchises which never had PC ports (for example Ace Combat 7 and Armored Core 6), not to mention that it seems much more likely for new japanese IPs to just have a PC port when they release these days (as long they're not exclusive).

japans fully behind pc nowadays. there's a reason why japanese devs of various sizes for the first time in the past few years have made pc ports of their games. Bandai, whose never had games like taiko no tatsujim, nor tekken on pc, and virtually the entire gundam franchise, puts most of the titles on pc. Capcom who never put monster hunter on pc till world, and always made pc a second thought, has put all of their titles. on pc now. Sega puts some of its largest IPs like Phantasy Star online on pc.

the same trend can also be seen in reverse, where a lot of wetern developers are having japanese language support in their games, one of the most popular in japan, being apex legends.

japan not being into pcs is very outdated information nowadays.

Weirdly the original Xbox and the 360 are full of Japanese exclusives. It was also the only place where you could play some Cave shmups.
