I was anyway already very motivated, have then started the manga book, but when you should then learn a whole table after the first few pages, I thought maybe Japanese offers from zero but better options. And indeed, when I get to the first half hour could already count to 999 motivated me very much. The exercises with the integrated Workbook also make super fun and you can tell whether you've learned enough itself. In addition, English is super easy, although I had a few years at school English, but it's really very simple English!
So really only be recommended for people who are motivated and who enjoy, even in small steps always more to learn to use the book and then thanks to the exercises that you successfully completed more motivated and to be proud!
A great book!
