Yamanashi Kofu City
A hidden hot spring near Shosenkyo where you can enjoy a beauty bath with 100% natural source water and a bouna sauna
"Yamamiya Onsen" is a day-use hot spring facility in Yamamiya Town, Kofu City, Yamanashi Prefecture. Located closest to Shosenkyo, it prides itself on fresh natural hot spring water flowing directly from the source with no heating, no added water, and no circulation. Its spring quality is a mildly alkaline sodium chloride spring, and its colorless, clear water with a smooth texture is well known as a "beauty bath." The sauna is a pleasant, high-humidity bouna sauna, where heat and moisture gently flow in from behind, letting you warm up comfortably without feeling short of breath. Paired with a cold plunge bath for one person that constantly overflows with water, it is a hidden gem of a hot spring facility where you can relax deeply amid an elegant Japanese atmosphere.
A luxurious natural hot spring with 100% natural source water, with no heating, no added water, and no circulation, and with constant overflow. This colorless, clear mildly alkaline sodium chloride hot spring at pH 7.7 is loved as a "beauty bath" for its rich, silky-smooth water. It has two indoor baths: one with the source water as-is at a warm temperature, and one high-temperature bath for slowly warming the body, plus a pot bath in the outdoor area.
A bouna sauna with the heater built into the back of the bench, circulating heat and pleasant steam from there. While the room temperature is mild, the properly controlled high-humidity setting makes it easy to breathe and allows you to sweat thoroughly from deep within your body. In a quiet, calm wood-grain space with music box BGM, this is an exceptional sauna where you can relax completely.
[Closed days] The 1st and 3rd Wednesdays of every month (open if it falls on a public holiday)
