I have some Spanish and Italian 'easy reading' books. On the back it says how many words you have to know and if there are additional words, it's explained. There are different levels. Most books are based upon 'real' literature. Some even start with a knowledge of 200 words.
Does anybody know if and where I can find this kind of books, using kana? (I can imagine, for higher levels, kanji are added.)
On the internet I found children's stories, but they don't only use basic words.
Or is teddybear a basic word?
