Chock-full of information, with great illustrations and an easy-to-read, fun style: Yurei Attack is well-worth picking up if you're interested in the world of Japanese ghosts.
Yurei Attack is the third in a series of books by authors Hiroko Yoda and Matt Alt about Japanese history, folklore and strange mythical beasts. This time around they've tackled yurei, the kind of Japanese ghosts that populate recent J-horror films like The Ring and The Grudge.
The book is written in a survival guide-style format, with full-color pages detailing the ghosts' origins, methods of attack, and, most importantly, tips on how to avoid their wrath. Each yurei is profiled separately, with illustrations by Shinkichi, a Japanese manga artist who doesn't hold back, portraying the often pretty terrifying stories in all their bloody detail.
For a book written in this format and full of illustrations, it's easy to get the impression Yurei Attack is for kids, but it's actually for mature readers, full of the aforementioned graphic images and comprised entirely of "real" information - that is, all the stuff in the book comes from real Japanese legends.
For that reason, the book is a really great resource for learning these horror stories, which are known universally throughout Japan. The spooky stories a culture tells around the campfire at night can reveal a lot about them, and if you're interested in Japanese folklore and culture, this is a great place to start.
