Breakthrough Japanese : 20 mini lessons for better conversation
(Book)

Each lesson begins with a common question of the sort that every student struggles with. Following this is an explanation in clear English, and a variety of example dialogues, vocabulary, fill-in-the-blank exercises, and puzzles. The lessons are presented in a lively manner and also illuminate aspects of Japanese culture. The 20 lessons in this book don't teach fluent Japanese overnight, but they should impart knowledge and style normally associated with years of living in Japan.
