Matsunoyama Onsen Taka-no-yu

Matsunoyama Onsen is famous for its high-temperature, salt-rich water that is believed to be fossilized seawater from 12 million years ago. Taka-no-yu is the primary public bathhouse in the village. The water is highly concentrated with minerals and has a distinctive petroleum-like scent, which is a hallmark of its therapeutic strength. The facility features a modern indoor bath and a small outdoor area. Because the water is so potent, it is known for warming the body to the core, making it a favorite for those visiting the 'Snow Country' during the heavy Niigata winters. The onsen is welcoming to all travelers and maintains a local, friendly atmosphere.
