I enjoy finding words like this. Words that are advanced (N2, N1, or beyond) that use kanji that even beginners on WK have learned (level 10 or lower), and obviously they aren’t words taught on WK.
These are easy to neglect because you don’t learn them early on, but then can be frustrating to encounter because it feels like you should know them.
The frequency ranking on the right comes from this list of the top 15000 words in Japanese.
I bolded some of my favorites.
I know there are anki decks with this kind of thing, but I thought people might be interested in just browsing some here too.
If I made any mistakes (particularly in the readings), let me know.
