Hyakki Onsen: Cozy Idle Inn

Manage a peaceful Japanese hot spring inn alongside 50 charming yokai companions in this cozy idle simulation game! Even while you are away, your inn collects Yudama (in-game earnings). Expand bathhouses, renovate facilities, and 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. Deep in a misty mountain valley stands an abandoned bathhouse. A Kappa scrubs the cypress tubs, a Bakeneko fluffs the futons, and a Chochin-obake lantern lights the path for travelers. As the Innkeeper, build a welcoming hot spring retreat with your friendly yokai staff. ■ Cozy Idle Progress: Earn While You Rest Your inn gathers Yudama while you work, study, or sleep. • Offline earnings accumulate for up to 8 hours initially. Renovations can permanently extend the limit. • Return to collect Yudama, upgrade facilities, and check on your yokai. ■ 50 Distinct Yokai to Collect & Assign Yokai work across five roles: Bathkeeper, Room Attendant, Chef, Gatekeeper, and Parlor Attendant. • Meet folklore favorites including Kappa, Yuki-onna, and the Nine-tailed Fox. • Discover their personalities in the Yokai Record: Akaname sees bath cleaning as a midnight snack, while Amanojaku welcomes guests by telling them to stay away! • Match staff to ideal roles for a 1.5x efficiency bonus. • Collect 48 Emaki scroll scenes: 38 regular scenes and 10 rank or seasonal outfit scenes. • Earn rank outfits as bonds deepen. At Old Friend rank, unlock each companion's Nishiki illustration and three-page story. ■ Generational Renovations & Prestige Develop 13 facilities and renovate when your inn's reputation reaches key milestones. Carry forward Spirit for permanent enhancements on the Spirit Tree. Watch your bathhouse grow across six generations, with grander buildings and changing mountain views. ■ Direct Recruitment at the Yokai Shrine: No Paid Gacha Choose a candidate and recruit that exact yokai with earned Yoki and a recruit slot. Slots recharge by 1 per day, up to a bank of 14. One optional ad-supported slot refill is available each day. While newcomers remain unowned, an extra introduction appears when none is among the regular candidates. Home-screen guidance points to an available recruit. ■ Two Ways to Welcome Guests In Woodland Baths, match animal groups to two baths by water temperature and group size. Plan at your pace across five turn-based stages. Record nine species, including mystical visitors, in the Woodland Guest Book after a satisfying visit. Earn Yoki for milestones, with no Yudama cost to play or retry. Classic hospitality also remains: choose the yokai best suited to a guest's request and earn rewards for successful service. ■ Transparent, Player-Friendly Design • No paid random gacha, paid gameplay currency, forced interstitials, or banner ads. Rewarded video ads are optional. • The one-time Video-Skip Talisman lets you claim eligible rewarded bonuses without watching videos. Daily caps, reward amounts, and conditions remain unchanged. • Preview Seasonal Sets before purchase. Outfits and decor are visual only; they do not affect stats, income speed, or progression. • Each of five Seasonal Sets covers outfits for all 50 yokai. If you already own a matching Seasonal Set, the newcomers' outfits are included with no extra purchase. Legacy signboard and noren artwork-only products are separate from outfit sets. Morning bath, midday soak, evening dip. The water is warm and ready. Welcome home to Hyakki Onsen.
