Soak in an ultra-cold cold plunge bath fed by the spring water of the famed Tateyama peaks, and a richly fragrant hinoki sauna
Toyama Uozu City
"Tsuji Wakuwaku Land" is a minshuku attached to a super sento in Uozu City, Toyama Prefecture. The highlight of the large bath area is the cold plunge bath, which uses underground spring water from the Tateyama Mountain Range pumped up from below ground and poured in free flow as is. Kept at 13°C year-round, its crisp water combines a sharp, skin-prickling sensation with the mellow quality unique to natural water. The sauna is a dry sauna with luxurious hinoki wood used throughout the interior, offering powerful heat and a pleasant wood aroma. The variety of baths is also appealing, including a high-concentration carbonated spring and the first spindle jet bath introduced in Hokuriku. In 2023, a private sauna was also added in a separate area, making this a facility where you can refresh yourself in a wide range of styles.
TypeArtificial Hot Spring
An artificial hot spring made by passing water through special medicinal stones to infuse it with minerals. The water is extremely mellow and gentle on the skin, allowing you to warm up slowly from deep within the body. Combined with functional baths such as the high-concentration carbonated spring and jet baths, it offers an even greater refreshing effect.
