Yunotsu (温泉津) is a hot spring town in Shimane.
A one-street onsen town with several inns and two beautiful old public bath houses, Yunotsu is a piece of 1920s Japan (think Studio Ghibli) that somehow survived into the 21st century, full of classic wooden buildings and geta clip-clopping on the street.
JR Yunotsu station on the Sanin line is almost a 1km walk from the main part of town. There is limited bus service to and from the station. If you have a reservation at a ryokan or inn in town, ask them to pick you up.
By car, Yunotsu is on Route 9 about 30 minutes drive from Iwami Ginzan UNESCO World Heritage site in Oda.
As an onsen town, the main activity here is bathing. Although your inn or hotel may have natural hot spring water pumped in, going out to visit other baths is well worthwhile.
The town is pretty quiet, things close up early, and there are not not many options aside from the inns that line the main street. Yunotsu does have a small, but high quality sake brewery called Kaishun (開春)  if you want to try what the locals drink--widely available in town.
