The title of this book is EXTREMELY misleading!
I bought this with the assumption this was an Otaku travel guide to Japan. I was sorely wrong. This is a manga, with a page here and there containing blurbs on Otaku spots in Japan.
I was sorely disappointed so I returned it the same day and purchased Cruising the Anime City: An Otaku Guide to Neo Tokyo. Totally worth it and yes, an Otaku guide to Japan (go figure).
