Please let me know your recommended secret hot springs!

For the past few years, my friends and I have been trying to visit one secret hot spring a year. Please let me know if there are any secret hot springs we should visit🙏 By the way, my current best secret hot spring is "Aoni Onsen Lamp Inn" As the name suggests, it is a lamp inn with no electricity. The atmosphere from the evening to the night is fantastic and highly recommended. The bath has a great atmosphere too!! However, you cannot use a hair dryer. I stopped by a hot spring before going to the inn and washed my hair before heading there. ⚫︎Secret hot springs I have been to (including stopovers) Nyuto Onsen Tsuru no Yu Koganezaki Furofushi Onsen Osawa Onsen Sansuikaku Sujiyu Onsen Yamaai no Yado Kiyasuya, etc. #Comment Circle #Secret Hot Springs #Secret Hot Spring Tour #Lamp Inn #Domestic Travel #Hot Springs #Japan
