A statement on the official website reads: “In-keeping with Japanese tradition Onsen’s will not mix genders during this session. The Onsen’s will be all male or all female, dependent on your group.
“If you prefer to keep your bathing suit on, don’t worry we’ve got you covered as there are plenty of sessions throughout the day to keep your cozzy on.”
Each session of the ‘newest’ ancient tradition for Brits over the age of 18 to try out lasts up to 45 minutes and is free of charge.
