I've fallen down a rabbit hole of works in the Japanese public domain.
this is a real weird rabbit hole because it's a Big lot of works by a bunch of people with whom I am mostly not familiar (and a couple who's works I know pretty well), mostly untranslated (because the translations would still be under copyright), and almost all from pre-1954.
Which, of course, means that I'm also contending with the history of imperial Japan in the lead up to, during, and in the aftermath of the second world war.
