About This Game

Welcome to the onsen house beyond the eyes of the living.

Yokai Onsen is a cozy idle onsen management game that sits at the side of your screen. When the human world sleeps, weary yokai and spirits visit your bathhouse to cleanse their burdens.

Take on the role of Aki, a mysterious onsen house owner, and manage the onsen with your spirit companion Ku. Greet yokai guests, renovate rooms, earn gold, and grow your steamy business.
