But at the end of the day it makes sense that a japanese company would cover their ass (pun intended) and make it clear in a contract.
It's also the responsible thing to do and western companies/streamers should also do it, at the very least for japanese games (eg. any Nintendo game).
I don't think the problem is the perms but whatever makes it sometimes hard/long to obtain.
