Experience the warmth and charm of nearly 400 years of history

Established in 1639, the construction Shimogoten inn was ordered and financed by Nanryu-in (Tokugawa Yorinobu), daimyo of the Kishu-Tokugawa clan. The name Shimogoten was also officially bestowed by the daimyo, and its rich traditions and heritage have been preserved to this day.

Hot springs

Ryujin hot springs, one of Japan's top three beauty-enhancing waters

The rich history of the Ryujin hot springs stretches all the way back to the 700s, when these beautifying waters were originally discovered by traveling religious pilgrims. It is said that they were later developed as the result of a prophetic dream famed Buddhist monk Kobo Daishi himself.
Nanryu-in, daimyo of the Kishu-Tokugawa clan, was completely taken by them during the Edo period--so much so that he tapped the clan coffers to have accommodations built here. They were used as a beloved retreat for generations of clan leaders, who frequented them up until the clan system was abolished in the late 1800s. The waters themselves are carbonated alkaline springs with an abundance of radium, and are counted among Japan's top three bijin-no-yu, or beauty-enhancing waters, alongside Kawanaka hot springs in Gunma Prefecture and Yunokawa hot springs in Shimane. These beautifying springs remove excess skin oil and impurities while stimulating healthy liver activity. This not only creates fresh, baby-smooth skin, but also helps promote beautifying processes within the body. Come to this a gorgeous forest hideaway for an indulgent, soothing experience that will purify both body and mind.

Indoor baths (Hinoki Bath, Ozashiki Bath)

The Ozashiki bath is a particularly luxurious experience, with the changing rooms, washing areas, and tubs all laid with authentic tatami mats. Take all the time you need to relax and indulge as the babbling sounds of the pristine Hidaka River drift in through the open windows. (Men and women alternate morning and evening access. Open to day guests as well.)
