In July 2022, JGov's "Study Group on Measures to Deter Access to Pirated Sites on the Internet" published a Draft Status Summary.

A DeepL translation is the best we could do, but a translated version is available here:

There are some interesting takeaways from the document.

1) JGov is leaning on Cloudflare to help them choke out manga piracy sites. Apparently 9 out of the to 10 pirate sites use Cloudflare services... which is fucking embarassing

2) By the study group's own admission, working with international law enforcement and the private sector to shut down some big manga pirate sites had basically no effect, as new sites came in to fill their place and the total traffic either stayed the same or increased.

3) They more or less say flat out that last year's amendments to the Sender Information Disclosure Law, despite being shoehorned in over the oh-so-tragic suicide of Hana Kimura and ostensibly being created to stop online slander and harassment, are mostly just helpful for them in doxxing pirates.
