This all seems pretty academic considering there doesn't appear to be any runs with the Japanese version in the top 100 PC easy NG+ times. I would assume that the vast majority of the Japanese community is on console, which anyone can freely purchase regardless of region. Complaining about cost is silly, because this is an enthusiast hobby that has a high barrier to entry to begin with (gaming PC/PS4, a copy of the game).

Like almost all hobbies, to be the best, you have to be willing to devote a lot of resources, ie time and money. If you cannot afford it, that's a bummer, but such is life dude.
