Senami Onsen
瀬波温泉
On the Sea of Japan coast at Murakami in northern Niigata, Senami Onsen was discovered in 1904 when oil prospectors struck near-boiling water instead of crude. Its 95 °C sodium-chloride springs face straight out to sea, famous for sunsets sinking into the water beside the open-air baths.
