So I’m learning Japanese and I’d love to have more practice material, but from what I can tell most (maybe all) of the manga available from the several sites I checked on the Megathread wiki only had translated books. Many languages, tbf, but I could not find the original Japanese anywhere. Am I just missing it or is there a particular source I should look at for untranslated books?

Also as a corollary, anyone have a good source for visual novels in Japanese?
