Counts from the Tanaka Corpus index via Tatoeba, 1,178,504 words of segmented Japanese. Tatoeba sentences are contributed by learners and teachers, so frequencies reflect textbook Japanese rather than a general corpus. Compound readings are generated — from the corpus where it records one, otherwise from a tokenizer — and are omitted rather than guessed where neither resolves the word. Character meanings and on/kun readings are written by hand.
