RYOKANS providing rooms with private open-air/Onsen baths
February 02, 2016 update
Japanese people generally regard people with tattoos as gangsters, yakuza, that should be avoided.
This is why people with tattoos are often forbidden in large public baths that are shared by everyone.
However, people with tattoos can enjoy hot spring baths in private-use hot spring baths, guest rooms with private open-air baths, and so on as they cannot be seen by others.
Please make your reservations at this site as it introduces many facilities such as ryokans with private-use hot spring baths and ryokans with guest rooms that have private open-air baths.
