Japanese Kanji: How the System Actually Works (and Why 2,136 Isn't the Number That Matters)
Most people meet kanji as a threat: 2,136 characters, each with several readings, each apparently drawn from scratch. Framed that way it looks like years of flashcards before you can read a menu.
That framing is wrong, and it's why so many learners quit at this step. Kanji are not 2,136 unrelated drawings. They are a compositional system — a small set of parts, recombined — and roughly two thirds of them tell you how they're pronounced if you know where to look.
This is how the system works.
