Best when you want a full onsen destination, with enough range in Beppu and the wider area to build the trip around soaking.
Best for a heritage-led onsen break, where Dogo gives you landmark bathhouse atmosphere without turning the day into a heavy bath…
Best when you want a real mountain onsen-town escape, where famous baths and the town around them matter equally.
Best for a walkable bath-town stay, where yukata strolling and hopping between public baths are part of the pleasure.
