Because fundamentally the JRPG was was a pixel art gallery with decent music layered with a moderately esoteric american rules engine and presented as something of a visual novel. The long play times were appealing in a world where most games lasted an hour and even fewer didn't end up with you spending that hour marveling at how shitty the game was. It never really worked out when 3d environments took over because Japanese aesthetics just look really weird which is why at best you see really shitty CG used in anime to speed up production of background dudes and such. The rise of western adventure games which were just as long and just as entertaining with ever improving graphics meant audiences didn't have to tolerate Japan's weird little girl panties and oppai milf fetishes.
That's not to say Japan can't produce some awesome games, because it can, but the JRPG became the stomping grounds of the otakus and the weebs who hyper focus on the genre, to the point there are entire discussions about which child character had their panties censored for the American release.
