Daiichi Rotenburo, or the first open-air bath exclusively for ladies at Kaniyu. (photo: Nov. 2009)
I went hiking last Sunday to Okukinu Onsenkyo (奥鬼怒温泉郷) in Tochigi Prefecture. There are four onsens at Okukinu Onsenkyo; NIkkosawa, Teshirozawa, Hacchonoyu and Kaniyu. All of them but Teshirozawa accept day visit soaking and I visited all three. Kaniyu (加仁湯) is the biggest among them.
There are one rotenburo for ladies, many mixed gender rotenburos, gender separated indoor baths, and some private baths for overnight staying guests. They have five fountainheads.
