Japanese for Busy People Ser.: Japanese for Busy People I : The Workbook for the Revised 3rd Edition by AJALT (2012, Trade Paperback, Workbook,Revised edition)
Minna No Nihongo is one of the three leading book series for learning Japanese (alongside Genki and Japanese For Busy People). I love this series - although there are no explanations in English it is all fairly straightforward and adds to the immersion, even if you are beginner level. Each section is beautifully illustrated and most colleges and universities have chosen these books for their classes. Five stars all round.
