If I wanted to come to Japan to take the JLPT this year onward, what would be the steps to do so?

So apparently, the JLPT will now require a residency card to take the test in Japan while previously any tourist could just sign up to take it if they had a Japanese address.

Now, I'm asking here to get a better idea of what the process would/should be now. Is it going to be required to attend a language school? Do they provide residency card support? Is there a special visa to take the test? Any information would be helpful!
