Hi Article 19.
https://nichegamer.com/dlsite-temporarily-blocks-major-western-payment-processors/
There is a very concerning attack on freedom of expression which might be of interest to you. It involves a private actor attacking vast swathes of art / sexual expression (involving non-existent people). It should be permissible by the First Amendment (although, this isn't America) and the local law in Japan (and the Constitution, Article 19 / 21 of which protects free expression[1]).
A few of the articles on this site can be a bit on the conservative side but this one is fairly good.
Perhaps relevant:

1 Something which is often brought up is the Constitution there, examples of which include:
"Article 19. Freedom of thought and conscience shall not be violated."
"Article 21. Freedom of assembly and association as well as speech, press and all other forms of expression are guaranteed.
No censorship shall be maintained, nor shall the secrecy of any means of communication be violated."
From what I've seen, this right is not absolute. If someone deliberately posts non-consensual porn of someone (someone who actually exists), for instance, it wouldn't protect them from the law. However, that is a very different kind of case.
