Review Detail

From the very first pages it's easy to grasp the good quality of the content: the book is well written, without any sales pitch, and puts everything in context. It's an entertaining read, including phrase-by-phrase examples in both Japanese and English, that spans beyond the simple pick up techniques to a more comprehensive view on Japanese girls' mind set and expectations.
It's very easy to implement and at some point it reminded me of the Mystery routine based approach, with little "theaters" and pre packaged conversations. Some shared elements are also found with the book of Bobby Rio on conversation escalation but tailored to the Japanese context, with a few different core elements.
I read the 2013 edition, which may have targeted some of the critics of Angel's review, even though I didn't focus much on high-end clubs either (maybe because I share the limited-budget assumed perspective of the authors).
Great value for money, at this price point it costs less than the entrance fee of a club in Shibuya!
If you have doubts before buying it there is an episode on the DSR podcast with the interview of the authors, very entertaining as well!
P.S. Having met Japanese girls both inside and outside Japan I noticed quite a difference in their behavior. As you might expect, Japanese girls living or even just traveling in western countries have a more "western" approach to dating and relationships and things can move significantly faster than the book suggests, as written in the review.
