Value as a World Heritage Site
Oshino Hakkai was registered as a UNESCO World Cultural Heritage site in June 2013 as part of “Mount Fuji—Object of Faith and Source of Artistic Inspiration.” This recognition reflects the historical value of the site as an important pilgrimage destination in Mount Fuji worship.
Fujiko devotees would perform purification rituals at Oshino Hakkai before climbing Mount Fuji, cleansing their body and spirit before undertaking the ascent of this sacred peak. Each pool is dedicated to one of the Eight Great Dragon Kings based on the teachings of the Lotus Sutra, making it an extremely important place both religiously and culturally, carefully preserved to this day.
Designation as Natural Monument and Top 100 Waters
Oshino Hakkai was designated as a National Natural Monument in 1934 and was selected as one of Japan’s Top 100 Waters by the Ministry of the Environment in 1985. Snow accumulated on Mount Fuji percolates through the ground, passing between layers of lava (an impermeable stratum) over decades to centuries, and emerges as water of extremely high purity.
This spring water maintains a consistent temperature of approximately 13 degrees Celsius year-round and is characterized by exceptionally high transparency. Daily spring water volume is said to reach approximately 200,000 tons, and this abundant water supply is one of Oshino Hakkai’s greatest attractions.
The Eight Sacred Sites|Characteristics and Highlights of Each Pool
The eight pools comprising Oshino Hakkai are each designated as sacred sites with assigned numbers, and a defined pilgrimage route has been established. Here is a detailed introduction to the characteristics and highlights of each pool.
First Sacred Site: Deguchi Pool (Deguchiiké)
Deguchi Pool, the largest of Oshino Hakkai’s eight pools and positioned furthest north, has an area of approximately 1,467 square meters and a depth of about 0.5 meters. Located somewhat apart from the other seven pools, it attracts relatively few tourists, allowing visitors to enjoy Mount Fuji’s scenery in a tranquil atmosphere.
Surrounded by trees, the sight of nature’s seasonal beauty reflected on the water surface is exceptional. Particularly during autumn foliage season, the contrast between the colored leaves and Mount Fuji is beautiful and popular for photography.
Second Sacred Site: O-Kama Pool (O-Kamaike)
Although small with a diameter of only about 3 meters, O-Kama Pool has a depth of about 4 meters and, true to its name, has a pot-like shape. The water’s transparency is exceptionally high, with the bottom clearly visible, and many tourists are captivated by its mystical blue hue.
This is a valuable spot where one can observe the water welling up from the pool bottom at close range, and the way the water’s color changes depending on the angle of sunlight is another highlight.
Third Sacred Site: Sokonashi Pool (Sokonashiiké)
Sokonashi Pool is located within the grounds of the Harinoki Tree Grove Museum and can be viewed upon paying an entrance fee. The name “Sokonashi” (bottomless) comes from a legend that an object accidentally dropped during washing in the pool was later found in Yuki Pool, suggesting that the pools are connected underground.
This legend is a fascinating episode demonstrating that Oshino Hakkai’s pools are connected through groundwater channels. The surroundings of the pool feature traditional thatched-roof buildings, allowing visitors to experience Japan’s original landscape.
Fourth Sacred Site: Choroshi Pool (Choroshiiké)
Choroshi Pool is named after its elongated shape, resembling a sake pourer (choroshi). With an area of approximately 79 square meters and a depth of about 3 meters, the surrounding area features a water wheel house that creates an idyllic rural landscape.
The pool’s surroundings are relatively open, making it popular as a Mount Fuji photography backdrop. Spring cherry blossoms, summer greenery, autumn foliage, and various seasonal landscapes provide enjoyable scenery throughout the year.
Fifth Sacred Site: Yuki Pool (Yukiiké)
Yuki Pool has the highest spring water volume among Oshino Hakkai’s eight pools, with an area of approximately 152 square meters and a depth of about 4 meters. Approximately 2.4 tons of water per second spring forth, and its abundant water volume and high transparency make it the representative pool of Oshino Hakkai, attracting many tourists.
One can observe sand swirling up from the pool bottom and aquatic plants swaying, and the water’s blue is sometimes called “Oshino Blue” for its beauty. The pool’s surroundings are lined with souvenir shops and dining establishments, making it the center of tourism.
Sixth Sacred Site: Nigori Pool (Nigoriiké)
Despite its name meaning “turbid pool,” Nigori Pool is actually as transparent and beautiful as the other pools. The name is said to have originated from when volcanic activity from Mount Fuji once temporarily clouded the water.
With an area of approximately 36 square meters and a depth of about 1 meter, it is a relatively small pool with quiet charm. Located on residential property, viewers should exercise consideration when visiting.
Seventh Sacred Site: Kagami Pool (Kagamiiké)
True to its name, Kagami Pool is known for its water surface mirroring the surrounding scenery like a mirror. With an area of approximately 144 square meters and a depth of about 1.5 meters, on windless days one can see the beautiful “inverted Mount Fuji” reflected in the water.
Early morning and dusk provide particularly beautiful scenery, making it an ideal photography spot for photography enthusiasts. The pool’s surroundings are in a quiet residential area, allowing for relaxed strolls.
Eighth Sacred Site: Shobu Pool (Shobiiké)
Shobu Pool has an area of approximately 269 square meters and a depth of about 1.5 meters. Its name comes from iris flowers that once grew in abundance around the pool. Currently, iris flowers bloom in early summer, allowing visitors to experience the charm of the season.
A well-maintained walking trail surrounds the pool, allowing visitors to savor the beauty of spring water while leisurely strolling. As the final sacred site of the pilgrimage, it has an atmosphere befitting its role.
The History of Oshino Hakkai and Mount Fuji Worship
Deep Connection with Fujiko
Oshino Hakkai has deep connections with Mount Fuji worship, particularly Fujiko, a faith-based organization. Fujiko is a religious organization that venerates Mount Fuji as a sacred peak and performs pilgrimages to climb it, becoming widely popular among common people during the Edo period.
Before ascending Mount Fuji, Fujiko devotees would purify themselves at Oshino Hakkai, circulating among the eight pools to cleanse their body and spirit. The Eight Great Dragon Kings enshrined at each pool are water-governing dragon deities from the Lotus Sutra and have been worshipped as protectors of Mount Fuji’s water sources.
Eight Great Dragon King Worship
The Eight Great Dragon Kings refer to eight dragon deities: Nanda, Bhananda, Sagara, Vasuki, Takshaka, Anavatapta, Manasvi, and Utpala. These dragon kings were positioned at each of Oshino Hakkai’s pools, with each pool serving as a sacred site.
Today, each pool has small shrines and stone monuments carefully maintained by local residents. Every August, Oshino Village’s largest festival, the “Eight Pools Festival,” is held, expressing gratitude to the Eight Great Dragon Kings and reverence for Mount Fuji.
Spring Water Mechanism
The spring water of Oshino Hakkai originates from rain and snow that fell on Mount Fuji, percolates deep underground, and flows through lava layers over a long period. During this process, water is purified by a natural filtration system that removes impurities, becoming extremely pure.
Geological research has revealed that the spring water originates from rain and snow that fell on Mount Fuji approximately 20 to 80 years ago. This natural filtration process, taking a long time to complete, creates the transparency and beauty of Oshino Hakkai’s water.
