From publisher blurb:
For centuries, the Japanese have called their islands the Land of the Rising Sun. Set in Feudal Age Japan, this sourcebook for 5th edition of Chivalry & Sorcery features a Bestiary drawn from the folklore of the Japan of legend. Within these pages you will find details of more than a hundred yokai, or creatures from Japanese folklore, along with game stats for Land of the Rising Sun.
This is more than just another book of monsters to kill, though. Like all creatures from folklore, wherever they may come from, each entity in this book has its own story, its own cultural significance, and its own particular challenges. Some may be overcome by force, but others require a more thoughtful approach. Some are linked to Japanese social mores and attitudes, and others to Buddhist or Shinto theology.
