The Onsen Trip

This was supposed to be the trip of a lifetime. You would go backpacking across the countryside enjoying all the many sights and vistas that would make your trip worthwhile. You started at the beginning of summer the perfect time to travel. You even came prepared with the right gear. The only problem is now you are Lost. GPS doesn't work. Phone is dead. You can't find the path. You have no idea where you are. Then you hear it before you see it. A rustic little building still covered by a thatched roof. In the distance you can see what you assume is steam. You've found an onsen, a mixed bathhouse that caters to any and all weary travelers. What will you do? Who will you meet? Will you find your way home? Maybe the Onsen owners know a way???
