九月八日、てんのうが こうきょの 田で いねを かりました。
五月に 自分の 手で うえた いねです。
かまを 使って、二十かぶを かりました。
お米は「ニホンマサリ」と「マンゲツモチ」です。
昭和の てんのうから つづく、たいせつな しごとです。
Why six school grades, and not N5–N1?
Because that is how Japanese children learn to read. Japan's Ministry of Education fixes exactly which character belongs to which grade — so "grade 3" is a boundary you can verify, not a feeling. Every article here is machine-checked: if a single character sits above its grade, it is not published.
The result: you never hit a character you have not learned. That is the whole reason this product exists.
