Just remember to bring your own towel!! They will sell you a small towel for 200yen or you can rent a decent sized one for 300 yen.
They also have a spa pool for kids in which is not as hot as the adults one. Clean facilities, with soap, and hair dryers provided. Foreigners and tattoos are welcome 😁
