647. Hotel & Renta Car 660, Nachikatsuura, Wakayama Hotel and car rental. Visited for day use at 500 yen. Day use available from 06:00 to 00:00. Bath photo from the internet matches. Indoor bath with clear water and sparse fine brown limescale. Temperature 42.5. Breathing inside is tolerable. A pretty unremarkable bath, but it's not every day you can go to an onsen at a car rental place. 04.11.2025
