Mostly read this to practice my Japanese reading, and having watched several of Kazu's videos and an interview he did on a Japanese channel, I decided to pick the book up. He has some solid tips but there is a lot of repetition and overly obvious information, so it felt like too much fluff for tips that could have been condensed into half or less the length of this book. Part of this could be that Japanese audiences prefer more reassurances and hand-holding through concepts but as an American reader I wanted him to get to the point. At any rate, it was good reading practice and highly understandable.
