Once my exams are over, I wish to study Japanese in my spare time (similar to me learning Piano, a full hour at least a day).
Can I ask to all you teachers or those who have teachers, or even those who are studying Japanese, what are the best formal books (for adults) to study from?
I have heard good reviews from the Genki series, but I want to know some others.
Thanks in advance.
