Hyakki Onsen: Cozy Idle Inn

Manage a peaceful Japanese hot spring inn alongside 40 charming yokai creatures in this cozy idle simulation game! Even while you are away, your inn steadily collects Yudama (in-game earnings). Expand bathhouses, renovate your facilities, and welcome mythical spirits to restore a forgotten mountain retreat at your own gentle pace. There is no paid random gacha and no paid gameplay currency. You choose which yokai candidate to invite to your inn. — Deep in a misty mountain valley stands an abandoned bathhouse. Human staff are nowhere to be found. But supernatural helpers? There are plenty. A Kappa scrubs the cypress tubs clean, a Bakeneko fluffs the cozy futons, and a Chochin-obake lantern lights the path for evening travelers. As the Innkeeper, the future of this secluded haven rests in your hands. Take a breath, relax by the rising steam, and build a heartwarming hot spring resort with your friendly yokai staff. ■ Cozy Idle Progress: Earn While You Rest Your inn gathers Yudama automatically while you work, study, or sleep. • Offline earnings accumulate for up to 8 hours initially. • Rebuild and expand the inn to permanently extend your offline time limit. • Return whenever you like to collect your Yudama, upgrade facilities, and check on your yokai. ■ 40 Distinct Yokai to Collect & Assign Yokai work across five essential roles: Bathkeeper, Room Attendant, Chef, Gatekeeper, and Parlor Attendant. • Meet folklore favorites including Kappa, Yuki-onna, and the Nine-tailed Fox. • Learn their whimsical personalities in the Yokai Record: Akaname views cleaning baths as a midnight snack, while Amanojaku invites guests by telling them to stay away! • Pair matching yokai with their ideal facility roles for a 1.5x efficiency bonus. • Unlock 43 beautiful Emaki scroll illustrations as you discover special yokai pairings. ■ Generational Renovations & Prestige Develop your inn across 13 unique facilities.
