What is Onsen Shrine? | The Head Shrine of Hot Spring Worship on the Shimabara Peninsula
Onsen Shrine is located at 319 Unzen, Obama-cho, Unzen City, Nagasaki Prefecture, and is known as the head shrine of the Onsen Shrines scattered throughout the Shimabara Peninsula. It is said that there were once as many as 18 Onsen Shrines on the Shimabara Peninsula, and it has long been cherished as a center of local faith.
While Onsen Shrines still exist in various locations such as Azuma Town, Chijiwa Town, Ariie Town, and Isahaya City, this shrine located in the Unzen Onsen area is considered the main shrine. It is a historical shrine deeply connected to the origin of the place name Unzen.
The Origin of the Place Name “Unzen” and its Relationship to the Onsen Shrine
The place name “Unzen” was originally written as “温泉” (onsen, hot spring) and pronounced “Unzen.” This is believed to originate from the mountain name “Onsenzan” of Onsenzan Manmyoji Temple, which was established as the temple managing the Onsen Shrine. During the era of syncretism of Shinto and Buddhism, Onsenzan Manmyoji Temple and the Onsen Shrine formed a single place of worship.
Although Manmyoji Temple was abolished due to the Meiji-era separation of Shinto and Buddhism, the Onsen Shrine inherited its tradition of faith and continues to this day. The change in spelling from “温泉” to “雲仙” is an important element that tells the story of the historical changes in this region.
History of Onsen Shrine | 1300 Years of Faith Since the First Year of the Taihō Era
Founding and the Legend of Gyōki Bodhisattva
Onsen Shrine is said to have been founded in the first year of the Taihō era (701 AD). According to legend, Gyōki Bodhisattva, a high-ranking monk of the Nara period, climbed Mount Unzen and founded Onsenzan Manmyōji Temple, simultaneously establishing Onsen Shrine.
Gyōki was a monk known for discovering hot springs in various regions and dedicating himself to the relief of the people. He is said to have discovered the efficacy of the hot springs in Unzen and established the area as a sacred mountain. Since then, Unzen has developed as a training ground for mountain Buddhism and a sacred site of hot spring worship.
Prosperity During the Era of Shinto-Buddhist Syncretism
From the medieval to the early modern period, Onsen Shrine enshrined Shimen-gū as the guardian deity of Onsenzan Manmyōji Temple, attracting worshippers in a form of Shinto-Buddhist syncretism. Manmyoji Temple, also known as Daijoin Temple, flourished as a center of mountain worship, with Mount Unzen considered a sacred mountain.
As a place of prayer for the entire Shimabara Peninsula, it functioned as a place that received various wishes from people, including those for agriculture, fishing, and recovery from illness. Combined with the therapeutic properties of the hot springs, it became a center of faith, attracting many pilgrims.
Changes Since the Early Modern Period
During the Edo period, it continued to develop under the protection of the Shimabara Domain. However, with the separation of Shinto and Buddhism in the early Meiji era, Manmyoji Temple was abolished. During this period, the syncretic form of Shinto and Buddhism was dismantled nationwide, and shrines and temples were separated.
Onsen Shrine survived as a shrine and continued to be a center of faith on the Shimabara Peninsula even after the Meiji era. In the Showa era, with Unzen being designated as Japan’s first national park, it also developed as a tourist destination. Onsen Shrine became a popular tourist spot.
Currently, in addition to its role as the local guardian deity, it is carving a new history as a shrine beloved by tourists visiting Unzen Onsen.
