How to use onsen hot spring baths

  • Please take the towels that are provided in your guest room to use at the public baths.

  • Take off your clothes in the changing rooms and enter the bath area. Note that bathing suits not allowed! You can take the small towel with you if you like, but please do not put the towel into the bath.

  • Very important! Please wash thoroughly BEFORE you enter the public bath. Use the washing areas where there are individual showers and small stools along with soap and shampoo. Do not enter the onsen bath unwashed.

  • Be sure not to stay in the hot water for too long. Many people prefer to get out from time to time for a cold shower to cool off.

  • Please enjoy!
