Yamanashi Tsuru City
An overnight onsen highlighted by a source-fed cold plunge and löyly heatwave
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.

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.

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.

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.

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.
