Yunoyama Onsen, located in the town of Komono in northern Mie Prefecture, has been soothing visitors since the Nara period.
This historic hot spring is said to have been discovered in 718 (the second year of the Yoro era) by the monk Jokun, following a divine revelation from Yakushi Nyorai (the Medicine Buddha).
It is also known by the alternative name "Shika-no-Yu" (Deer's Hot Spring), a name derived from a legend about an injured deer that healed itself in the waters.
Situated at the eastern foot of Mount Gozaisho—a prominent peak in the Suzuka Mountains that form the watershed between Mie and Shiga prefectures—Yunoyama Onsen also serves as a gateway to various hiking trails.
Visitors can enjoy the diverse flora that changes with the seasons, as well as views of unique granite rock formations and massive boulders known as "Komono-ishi." The area offers a variety of attractions and facilities worth visiting, such as the Paramita Museum and Komono Pottery Village within the town, and nearby sites like Tsubaki Grand Shrine and the BANKO archive design museum, directed by Koichi Uchida.
