History of Yudanaka Shibu Onsen Hot Spring Resort｜1,300 Years of Hot Spring Culture
The history of Yudanaka Shibu Onsen Hot Spring Resort is extremely ancient, with Shibu Onsen in particular said to have been discovered by the Buddhist monk Gyoki during the Nara period, approximately 1,300 years ago. Gyoki was a renowned monk known for discovering hot springs throughout Japan and dedicating himself to the salvation of the people, and Shibu Onsen was one of his discoveries.
The name of Yudanaka Onsen is said to derive from hot springs welling up from rice paddies, hence the name “Yu-da-naka” (hot spring rice field middle). During the Edo period, it flourished as a therapeutic hot spring resort, and is well-known for being visited many times by poet Kobayashi Issa, who composed many haiku on this location, such as “Yudanaka ya / snow mountain in view / morning bath.” Today, a walking path called “Issa’s Trail” exists in Yudanaka Onsen.
After the Meiji period, as Shiga Kogen was developed as a ski resort, Yudanaka Shibu Onsen Hot Spring Resort developed as its gateway. It grew into Shinshu’s representative hot spring resort as a year-round destination, welcoming ski guests in winter and summer tourists and mountain climbers in summer.
After World War II, while maintaining its function as a therapeutic resort, it strengthened its role as a tourist hot spring destination. In particular, at the 1998 Nagano Olympics, Shiga Kogen hosted skiing competitions, and Yudanaka Shibu Onsen Hot Spring Resort welcomed many athletes and tourists.
