I love the approach it uses to learning the hiragana chart. The first two chapters of the book are all in Romaji, but in every lesson it presents new characters and so next lesson Roman letters are Replaced with the characters thathave been learned already. By the end of the book, you will be able to read and write all Hiragana characters. Second Book Covers Katakana and third starts with Kanji.
The only disadvantage Is that it has no CD. In order to listen to the pronunciation, one has to check their website Where They have Actually sounds. But then again, you have to pay a monthly subscription to access the audio / video files. The book, therefore, has a few typing errors, but They are insignificant.
All in all, "Japanese from Zero!" is fun and entertaining.
Personally, I enjoyed it very much.
