Gin no Yu hot spring

344. Gin-no-Yu Hot Spring, Arima Onsen Public onsen in Arima for 700 (or 1200 for a combo ticket for Gin no Yu + Kin no Yu). Operating hours listed as 09:00-21:00 (except the first and third Tuesday of each month). Bath photo from the internet, matches reality. Inside there's a large bath with a bubble zone. Clear water, temperature around 43. Breathing is fine. There's a sauna. On one hand the bath is very simple, on the other it's constantly packed with tourists (during prime time a queue may form since they run out of locker keys in the changing room). So functionally you have an old-school onsen, but atmosphere-wise it's a tourist pass-through. Recommended to skip.
