This book is thin to the point of looking anemic. I expected more, better information and instead I was rather disappointed. The various regional sections are very poor in content, with only a few creatures per section and the individual articles rarely covering an entire page. The articles themselves are almost devoid of anything besides cursory information. "Oh? A Kappa has a bowl shaped depression on its head which is filled with water?! That is exactly what wikipedia says!!! Any 5 year old Japanese kid knows that! What about that they taught humans sumo and bone setting? No? PATHETIC!" This book will only leave you wanted more and feeling like you wasted money, neither of which are good feelings. Save yourself the lost sleep and guilt.
