(Dormy inn is one of my go-to chain, I think all have free late night ramen, onsen/sento, frozen milk dessert by the onsen at night, yakult by onsen in the morning

Super hotel chain, some of them have onsen/sento, their main page has a diagram describing which has what.


Anyone know of other chains with onsen/sento?
