An overnight onsen highlighted by a source-fed cold plunge and löyly heatwave
Yamanashi Tsuru City
Located in front of Fujikyu Tsuru Station, Yamanashi Overnight Onsen Yorimichi no Yu is a stay-oriented spa that integrates lodging, hot springs, and sauna. The auto löyly sauna delivers a rapid surge of heat, and the source water mixed with groundwater in the continuous-flow cold plunge bath cools the body core. The water is a sulfate spring with a soft touch that leaves skin feeling moisturized. The outdoor relaxation area deepens breathing, and the facility functions as a lodging that helps you totonou (achieve a state of perfect relaxation), letting you reset your senses during a journey.
TypeNatural Hot Spring
The spring is a sodium-calcium sulfate spring (hypotonic, alkaline, low-temperature). The source temperature is 32.9°C and is heated before being used as a continuous-flow supply to rock baths and other facilities. The moisture-retaining properties of the sulfate combined with alkaline softness leave the skin feeling moist and well hydrated after bathing.
Sauna TypeDry Sauna
Stove TypeConvection Stove (Sauna Stone)
Capacity36people
This is the facility's signature sauna. It is a far-infrared sauna equipped with the Finnish iznes stove, and automatic löyly is released at :00 and :30 each hour. In addition, staff provide löyly heatwave services, offering a professional aufguss experience that rapidly raises the perceived temperature.
Sauna TypeMist Sauna
Stove TypeBuilt-in Stove
A mist sauna that recreates a traditional Japanese kiln bath in a modern way. Steam continuously billows, surrounding you in a surreal, dense-fog-like atmosphere. The temperature is set very high for a mist sauna, overturning the conventional wisdom that mist saunas rarely induce totonou; you can enjoy a robust totonou (a state of perfect relaxation) experience.
Water QualityNatural Water (Groundwater, Spring, etc.)
Capacity6people
A rare cold plunge bath that mixes natural hot spring source water and natural groundwater. No chillers are used; the pumped water is drained as-is to achieve a soft, skin-friendly water quality. Regulars praise that you can stay in it for a long time, and the smooth, slightly slippery texture derived from the spring is pleasant. After soaking following a sauna, pores tighten noticeably and it has notable skin-beautifying effects.
