Yokai Bestiary 5E

Introducing the Yokai Bestiary-a Fifth Edition supplement featuring spirits, demons, and monsters inspired by Japanese folklore!

Designed for both players and Game Masters, this guide is packed with all-new creatures and legends that explore their backgrounds, origins, and unique lore. Getting ready for your next campaign or looking for a fresh story hook for your upcoming adventure? Add something new and unusual— like the tales of the Land of the Rising Sun!

For each monster, we've included a page featuring a legend rooted in authentic folklore, exploring the creature's origins, the reason for its appearance, the consequences of its arrival, and how to defeat this evil. Not all monsters are truly malicious or dangerous - some are merely troublesome - but each one has its own story, motives, and goals. On the following page, you'll find a detailed monster stats block along with adventure hooks and, in some cases, tips for the GM.

We designed these monsters with a party of 1-3 players in mind, specifically at levels 7-10.

What's inside the book?

40+ Monsters. These creatures span a range of elemental affinities—spirits, ghosts, undead, and shapeshifters—embodying centuries of accumulated dread across these islands. They’ve been waiting for the day we’d gather all this lore and transform it into one book, made specifically for your campaign or adventure.

Unique Stories for Every Monster. Legends of the undead, tested by time and passed down through countless generations, have always been met with awe and respect for tradition. These very tales laid the foundation for our monsters’ stories, revealing each creature’s essence, unique background, hidden mysteries, and the ancient wisdom of elders.

Adventure Hooks. Your group can quickly dive into any monster’s story by leveraging its background and the included plot hooks.

Monster Stat Block. Detailed stats, GM tips, and all the necessary information for bringing each monster into combat can be found here.
