@JapanAnon @Someguy @charliebrownau Oh, I found it:

Cosmotheism seems to be the only one that isn't Cuckflared, which means it's the only one I can access.
It seems like it does ship to Japan, although seems like I'll have to pay more for shipping than for the book itself, even when choosing the cheapest option.
Guess I'll find a PDF version and download that as a torrent, then I'll just donate to Dalton-san directly if he accepts donations.
