Can I go in a hot spring or a public bath even if I have a tattoo?

Tattoos are currently prohibited in most hot springs and public baths in Japan, but there are some facilities that accept tattoos if they are small or covered up by a special adhesive. There is no known list of tattoo-friendly facilities, so please confirm with the facility at the time of booking. It is also a good idea to book a room with a private bath at a ryokan, or book a private family bath if the facility has one.
