We went to 3 hot spring places while staying in Beppu and this Hyotan Hotsprings is one of the best!
They are open until 1 in the morning and is the only hot spring that has won three stars in Japan as a hot spring with the Michelin Guide.
The city of Beppu is covered with steam from hotsprings all the time, even in the night time.
They are huge and have many different kinds of baths!
Everybody can enjoy it and can even spend all day with their lounge and restaurant.
They carry Jigoku-gama (Steamer) as well.
