Even to study only the Japanese language is a very good book. You just go to the publisher's website (editions-ellipses.fr) for the corrected exercises in PDF format. This is the only negative point: a detachable booklet correction could have been inserted directly into the book for refractory people to the Internet or just do not have access to this media. But excellent overall. We are immediately immersed in the language with clearly explained grammar. I would recommend it.
