Hanabun Onsen Hotel, Tsubame Onsen Ryokan, Gensen no Yu Hanabun A ryokan with day-use bathing in Tsubame. It may not look especially attractive from the outside, but the bath is amazing. A kakenagashi sulfur spring, with large flakes of yunohana. The sulfur smell is not strong, but it stays on the skin for a long time. There are two rotating baths, on the 1st and 2nd floors. I got the 2nd floor one during my slot. The indoor bath has hinoki edges, and the water is hot at 42 degrees. A long hose for cooling the water leads into the bath. The rotenburo is incredible. There is a wide view of the mountain rising right in front of the ryokan, a huge green wall. In the distance, you can hear the river. Clouds drift right in front of the bath. 40-41 degrees. You can sit there for hours. There are sinks, shampoo, and hair dryers. Definitely recommended to visit.

RiverAbout
Hanabun sits in Tsubame Onsen (燕温泉), a remote hot-spring village in Myoko, Niigata, buried under snow each winter and reachable only by a winding mountain road. The water is a milky white sulfur spring, flowing fresh without recirculation, gentle on the skin. There are two sets of baths: indoor baths on the first floor and a second-floor indoor bath with an attached rotenburo looking out over Otagiri Gorge. The two sets rotate between men and women on an 80-minute schedule, so guests get access to both over a stay. Day use is also available in season. The inn draws from two separate spring sources, Kawara-no-yu (河原の湯) and Kogane-no-yu (黄金の湯), which also feed a pair of free public outdoor baths a short walk away. A small foot bath beside the inn is open to passers-by as well. Tsubame Onsen is said to have been discovered by the Buddhist monk Kukai (空海) in the early Heian period, and the wild riverside bath below is traditionally known as a hideaway of the warlord Uesugi Kenshin (上杉謙信).
