Too dull. I think the reason I didn't get on with this book is because I'm not the target audience. Yes, I was busy, but I wanted to learn the language to fluency, not at a passable beginner level. I'd rather take the (long) time to build solid foundations than start どうもうありがとうございますing in a thick accent and not being able to understand the reply. I also value more casual ability over the business-speak which is the focus here. I started my studies with Remembering The Kanji so the lack of kanji in this book is glaring. Once you know some kanji, reading sentences with them is easier than kana-only. I struggled to read sentences in this book that I would have read naturally if they had kanji in them. I've flipped through some of the later chapters and found that I can understand everything (after mentally putting the kanji back in), even if I wouldn't be able to say those things myself yet.
The textbook I actually used was Assimil's Japanese With Ease, which I much preferred. If I was to start again I'd probably go with Genki I and II along with the techniques described here: http://japaneselevelup.com/how-to-use.... I did follow those guidelines, but I used the Assimil textbook which is a bit more haphazard in its introduction of grammar concepts.
So if you're just needing some basic Japanese to survive business trips to Japan / hosting Japanese colleagues, this book is probably fine. But if you actually want to get to know the language in an enjoyable way, there are better beginner options.(less)
