This Onsen was founded 66 years ago and contains natural hot spring acids including ‘Meta-silicic acid’ which is very rare in Tokyo. The effects of this acid are extremely soothing for your body and will give you a glowing look after your bath as it has moisturising tendencies when mixed with water. The locals have given the Onsen water the nickname of ‘Beauty in the hot water!’ Be careful as it is closed on Tuesdays and is open from 16:00 to 1:30 the following day!
