But as I see it, any method that teaches learning kanji in isolation is not the most useful way to spend study time. I really think it’s necessary to learn kanji in pairs or as words at least. To memorize the 2 to 6 ways to read a single kanji doesn’t help you if you don’t know how to read it in what words, or the meaning of those words. Just learning the “meaning” of a single kanji is not often nonsensical or at the least not helpful in picking up new vocabulary.
