About Aeru no Yu
"Aeru no Yu" is an observation bathhouse inside Urakawa Yushun Village AERU in Urakawa, Hokkaido. Its appeal lies in the open, spacious atmosphere, with sweeping views of the majestic Hidaka Mountains. The baths use the rare natural mineral Black Silica (Shintenseki), known for its strong far-infrared effect, allowing you to warm up deeply from the core. The sauna area is also well equipped, featuring a high-temperature dry sauna and a cold plunge bath that is among the coldest in the Hidaka area. Whether as a refreshing stop after enjoying horseback riding and other activities or as a sauna-focused visit, it promises a highly satisfying experience.
