It’s on the right hand side at the beginning of Takaharu on 221.
Open till 10pm (Please check before going, a new one is being built so the site is a temporary one now). The head of doctors, Dr Agune speaks slow but very accurate English and is very understanding and patient.
Very close to Kirishima Temple, this is a mixed onsen where everybody wears white yukatas. There are a variety of onsen pools. Cost: 1800円.
At around 100 years old, this is Takaharu’s oldest onsen, with an A-structure building landmark.
