When you realize that the auto-translate is actually quite bad which is the real reason a lot of Japanese players doesn't use it, the sooner you'll realize it's not laziness.

When the majority of shouts you see, from NA players, consists of <hyur> <fun> <hole> <can I have it?>, do you honestly not wonder why the JP stopped bothering with it beyond localization reasons? It's well known the localization between languages for certain things is why it's not heavily used.

Also, JP only generally deals with "Japanese Language Only", I haven't seen anyone who attempts to communicate with them get kicked, it's the ones who try to join JP shouts and tell them to speak english are the ones who get kicked, btw, NA players are far worse with their "kicking/declining".
