About Yakuoin Onsen-ji Temple
Yakuoin Onsen-ji Temple (薬王院温泉寺) is a Shingon Buddhist temple formally known as “Reihousan Yakuoin Onsen-ji” located in Yamashiro Onsen, Kaga City, Ishikawa Prefecture. It maintains deep ties with the opening of Yamashiro Onsen and has served as the spiritual pillar of the hot spring town for over 1,300 years.
Counted as one of the Five Temples of Hakusan, it once boasted numerous subsidiary temples and branch temples numbering in the hundreds. Today, it still possesses many historically valuable temple treasures, including a wooden statue of the Eleven-faced Kannon (Goddess of Mercy) from the early Heian period and an image of Fudo Myoo (Immovable One) from the Kamakura period.
History of Yakuoin Onsen-ji Temple
Founding and the Hot Spring Discovery Legend by Gyoki Bodhisattva
Yakuoin Onsen-ji Temple’s founding is said to have occurred in 725 (Jinki 2) during the Nara period. During the reign of Emperor Shomu, the high priest Gyoki Bodhisattva visited this area while en route to Hakusan for religious training.
According to legend, Gyoki Bodhisattva discovered Yamashiro Onsen through the guidance of a sacred bird. Upon witnessing the hot spring’s emergence, Gyoki enshrined Hakusan Daikongen (the great deity of Hakusan), carved images of Yakushi Nyorai (the Medicine Buddha), and the Bodhisattvas of Sunlight and Moonlight along with the Twelve Divine Generals in a hall. This marked the beginning of Yakuoin Onsen-ji Temple.
Deep Connection with Hakusan Faith
Yakuoin Onsen-ji Temple is closely linked with Hakusan faith. Hakusan has long been revered as a sacred mountain, serving as a training ground for numerous ascetics and monks. As one of the Five Temples of Hakusan, Yakuoin Onsen-ji functioned as a base for Hakusan faith and also served as an important lodging temple on pilgrimage routes to Hakusan.
At its height, it commanded hundreds of subsidiary temples and branches, serving as the religious and cultural center of the Yamashiro Onsen area. It formed a unique sacred site culture where hot springs and Buddhist faith merged, drawing many pilgrims.
Myogaku and the Creation of the Fifty Sounds Chart
A particularly notable figure in Yakuoin Onsen-ji’s history is Myogaku (明覚上人), a monk from the mid-Heian period. Known as a learned monk who studied Siddham studies (the study of Sanskrit script) through independent learning in the early 11th century and left numerous written works, Myogaku is credited as the creator of Japan’s fifty-sound chart (the Aiueo ordering of the Japanese syllabary), contributing significantly to the development of linguistics.
Myogaku served as the second founder of Yakuoin Onsen-ji and devoted himself to the temple’s development. In honor of his achievements, a memorial pagoda was erected on high ground behind the temple. This pagoda, built in the Kamakura period, is now designated as a national important cultural property.
Changes from the Edo Period Onward
During the Edo period, under the patronage of the Kaga Domain, the temple continued its activities as the guardian temple of Yamashiro Onsen, deeply rooted in the community. It served as a spiritual refuge for those visiting for hot spring therapy and played an important role as a center of education and culture.
Despite the effects of the Meiji period’s anti-Buddhist movement and the separation of Buddhism and Shintoism, the temple was sustained by the faith of local residents and continues to this day as an iconic symbol of Yamashiro Onsen.
Highlights of Yakuoin Onsen-ji Temple
National Designated Important Cultural Property: Memorial Pagoda of Myogaku (Yakuoin Five-Tiered Stone Pagoda)
The greatest highlight of Yakuoin Onsen-ji is Myogaku’s memorial pagoda, commonly called the “Yakuoin Five-Tiered Stone Pagoda,” standing on high ground behind the temple. Erected during the Kamakura period, this stone pagoda is highly valued as a masterpiece of stone sculpture and is designated as a national important cultural property.
The five-tiered pagoda comprises five sections—earth, water, fire, wind, and space—expressing Buddhist cosmology. As a precious cultural property conveying Myogaku’s academic achievements and spirituality to posterity, it attracts many researchers and visitors.
Positioned on a high plateau, the pagoda area offers panoramic views of Yamashiro Onsen’s streets, allowing visitors to feel the weight of history amid a serene atmosphere.
Wooden Statue of the Eleven-faced Kannon from the Early Heian Period
Among the temple treasures housed at Yakuoin Onsen-ji, particularly valuable is the wooden statue of the Eleven-faced Bodhisattva Kannon carved in the early Heian period. The eleven-faced Kannon, a manifestation of the Bodhisattva Kannon, watches over and saves sentient beings from all directions and is revered for protection from misfortune and healing of illnesses.
This Kannon image, which retains distinctive characteristics of early Heian Buddhist sculpture, has long watched over the health and well-being of those visiting for hot spring therapy. Its delicate carving technique and serene expression convey the high artistry of sculptors of that era.
Statue of Fudo Myoo from the Kamakura Period
The statue of Fudo Myoo (the Immovable One) carved during the Kamakura period is also an important temple treasure of Yakuoin Onsen-ji. As the representative of the Wisdom Kings in esoteric Buddhism, Fudo Myoo is revered as a powerful Buddha who cuts through defilements and saves sentient beings.
Characteristic of Kamakura-period sculpture, it features realistic and vigorous expression, with the figure surrounded by flames and an angry expression conveying the power to drive away evil. In Yakuoin Onsen-ji’s role as guardian of the hot springs, Fudo Myoo occupies an important position as a protective deity of the sacred site.
Main Hall and Temple Grounds Atmosphere
The main hall of Yakuoin Onsen-ji is built on sloping mountain terrain, and its vermillion-colored structure surrounded by lush nature leaves a striking impression. The temple grounds, enveloped in silence and set apart from the hustle and bustle of the hot spring town, provide a space for quiet, focused worship.
Within the main hall, the principal image of Yakushi Nyorai (the Medicine Buddha) is enshrined, drawing constant visitors praying for healing and longevity. This unique form of belief, combining hot spring therapy and Buddhist faith, continues to be passed down.
From the temple grounds, visitors can view the streets of Yamashiro Onsen and surrounding mountains, enjoying nature’s seasonal beauty. Particularly during autumn’s fall foliage season, the grounds become vividly colored, attracting many worshippers and tourists.
