Anki Decks for Vocab not on WaniKani

There’s Torii SRS, which has a WK-exclusion mode, so you could learn the most common 10K words for example, without learning any of the ones you’d learn on WK. Works just the same as WK, has example sentences, audio, it’s very nice.

Then there’s Kitsun which is also amazing, they have community decks for some books, they have JLPT lists, WK expansion decks etc.

If you want to learn all vocab for a certain book / series, is amazing.

And I’d always recommend having a look through this amazing thread : The Ultimate Additional Japanese Resources List!
