Yokai Idle is a premium idle RPG inspired by Japanese folklore and history. Recruit Yokai, craft powerful equipment with randomized modifiers, and create unique builds as you journey through the Ages of Japan.

Your adventure continues for up to 24 hours while you're away. Battle dangerous Yokai, gather rare materials, complete Festivals, visit Shrines, and unlock new content at your own pace. Every action contributes toward expanding your collection, strengthening your build, and discovering new opportunities.

Recruit over 50 Yokai inspired by Japanese mythology. Each Yokai grants unique passive modifiers when equipped, allowing you to create completely different playstyles. Pair them with your chosen Class, elemental affinities, and equipment to discover powerful combinations—from devastating poison builds to elemental specialists and resource-focused characters.

Craft and collect equipment with randomized ARPG-style modifiers inspired by loot-driven action RPGs. Discover rare drops, enhance existing gear, or forge your own equipment using materials gathered throughout your adventure. Chase powerful modifier combinations, preserve valuable legacy items, and continuously refine your build as new content becomes available.

Progress through the historical Ages of Japan by funding grand Festivals that transform Onigashima. Each new Age introduces fresh currencies, materials, equipment, Classes, dungeons, Yokai, and crafting opportunities, encouraging you to rethink and evolve your build as the world expands.

With over 700 items, 50+ collectible Yokai, automated progression, offline play, cross-platform cloud saves, and full mod support through mod.io, Yokai Idle offers years of progression while respecting your time.

Yokai Idle offers a flexible adventure that fits around your life rather than demanding your attention.

Crafting in Yokai Idle is built around item customization and build creation, not simply producing the next tier of equipment. Weapons and armor can drop with randomized modifiers that dramatically change how your character plays.

Hunt for rare combinations, add new modifiers through crafting, improve existing affixes, or take risks to push an item beyond its limits. A poison-focused dagger, an elemental staff, or a defensive armor set can become the foundation of an entirely different build depending on the modifiers you discover.

Yokai Idle was designed from the beginning with modding in mind.

Most of the game's content is defined through easy-to-read JSON files, making it approachable even if you've never created a mod before. Add your own items, Yokai, enemies, professions, recipes, dungeons, quests, and much more without needing to learn a complex API.

Browse and install community creations directly through mod.io, or create your own worlds and share them with other players. Whether you want to make a small balance tweak or build an entirely new adventure, Yokai Idle gives you the tools to do it.
