Since apparently everybody in this thread has a PHD in Japan's company law system a few questions;

Destiny 2 & Tom Clancy's The Division 2 have anti-cheat and more recently EA's Apex Legends has added anti cheat (also making it unplayable on the Steam Deck in the process).
Anyway those 3 games have anti cheat but are available in Japan, yet people here claim that it's not allowed to have those anti cheats in Japan.. so how come?
And what about CoD & BF games? I don't really play shooter games so I don't know which games have them but the 3 above I mentioned I know have them.

Not that I'm pro anti cheat. Or well I don't mind anti cheat but I dislike those kernel level anti cheat which are actually spywere and take a hit on performance no matter if you're low end or high end hardware.

I'm just curious about the fact that those programs seems to be not allowed in Japan, yet several of those games (with those programs in them) seems to operate just fine in Japan?
