A Hot Spring Town That Flourished as a Purification Site for Kumano Pilgrims

Yunomine Onsen is a small hot spring village tucked into the mountains, about a 10-minute drive from Kumano Hongu Taisha. This ancient spring, said to have been discovered some 1,800 years ago, was traditionally used by pilgrims traveling to Kumano as a place for "yugori" — ritual purification to wash away the impurities of the journey. Inns and public bathhouses stand shoulder to shoulder along the narrow valley, while steam rises from the river below, creating the humble yet unmistakable atmosphere of a classic therapeutic hot spring town.

The World Heritage-Listed "Tsubo-yu"

The symbol of Yunomine Onsen is "Tsubo-yu," a small bath quietly nestled inside a wooden hut along the riverside. It is one of the component assets of the UNESCO World Heritage Site "Sacred Sites and Pilgrimage Routes in the Kii Mountain Range" — a rare example of a hot spring bath receiving such recognition worldwide. This tiny rock bath, just large enough for two people, is said to change color throughout the day and is enjoyed on a private, rotating basis. Legend has it that Oguri Hangan was brought back to life here, making it a place where visitors can truly experience the "waters of revival."

Make Your Own Hot Spring Eggs at the "Yu-zutsu"

Along the river flowing through the center of the village, you'll find the "Yu-zutsu," where scalding-hot spring water bubbles up from the source. Buy eggs or vegetables at the local shop, place them in a mesh bag, and dip them into the hot water — before long you'll have piping-hot onsen eggs. It's a small pleasure that makes for a memorable moment on your journey. The very act of waiting by the steaming river, wrapped in the scent of sulfur, becomes a treasured travel memory.

To Kumano Hongu Taisha via the Dainichi-goe

From Yunomine Onsen to Kumano Hongu Taisha runs a pilgrimage trail crossing the mountains, known as the "Dainichi-goe." Though only about 2 km long with an elevation gain of roughly 200 m, the path is short but steep, dotted with historic sites such as Hanakake Jizo and Tsukimigaoka Shrine.

Tips for Walking the Trail

After cleansing body and spirit in the hot spring, you can follow the same path taken by pilgrims of old and pay your respects at Hongu Taisha. Yunomine Onsen is far more than just a place for a quick soak — it is an essential gateway to experiencing the true spirit of the Kumano pilgrimage.
