Hot Spring Baths at Sanrojo

You may bathe in the sacred onsen water of Mt. Yudono at the Sanrojo Mountain Lodge that is located right next to the massive tori gate. These baths are open both to guests staying at the lodge and to the general public. This hotspring water is rich in the minerals of the mountains and the same water that is found at the shrine area of this mountain.

Please note that these are public baths and that there are no private bathing option here. See below for the two bath types of this lodge.

Sacred Hot Spring Guide

Located along the approach to the main shrine of Mt. Yudono, Niu Minakami Shrine enshrines the deity of water.

A rare carbonated mineral spring with a source temperature of 18°C continuously bubbles up from the earth. This sacred carbonated spring serves as the source for the Yudonosan Sanrojo “Kami no Yu” hot spring.

In the bathing area, the goddess Niu Tsuhime-no-Kami, known as the sister deity of Amaterasu Omikami, is enshrined. Visitors can immerse themselves in this divine hot spring, filled with gentle and sacred energy. Before entering, please bow respectfully toward the shrine altar within the bathhouse.

This is a place where one can experience the rebirth that lies at the heart of Mt. Yudono’s spiritual tradition.
