Kasamori Kannon-do (Chiba Prefecture) Complete Guide | Japan’s Only Four-Sided Suspended Structure, History, and Access Information
Located in Chonan-machi, Chosei-gun, Chiba Prefecture, Kasamori Kannon-do (Kasamori-dera Kannon-do) is an ancient Tendai sect temple situated in the central part of the Boso Peninsula. The Kannon-do, built on a massive rock, is known for its unique architectural style, the only one of its kind in Japan, known as “Shiho-kakezukuri” (four-sided suspended construction). As a nationally designated Important Cultural Property, it attracts many worshippers and architecture enthusiasts. Also known as the 31st temple of the Bando Thirty-Three Kannon Pilgrimage, this temple, with its mystical space woven from history and nature, is a representative tourist spot in Chiba Prefecture.
Overview and History of Kasamori Kannon-do
Founding and Dengyo Daishi Saicho
The history of Kasamori-dera is ancient, dating back to Enryaku 3 (784). The temple’s founding is attributed to Dengyo Daishi Saicho, who carved an eleven-faced Kannon Bodhisattva from a sacred camphor tree and enshrined it on the mountaintop. Saicho was the founder of the Tendai sect, establishing Enryaku-ji Temple on Mount Hiei, and played a crucial role in the history of Japanese Buddhism. It is said that he chose this location because he was drawn to its sacred natural environment and the mystical power of the massive rocks.
Imperial Prayer by Emperor Go-Ichijo and Construction of the Kannon Hall
The current Kannon Hall is said to have been built in 1028 (Chogen 1) by imperial prayer of Emperor Go-Ichijo. An imperial prayer signifies construction by imperial order, indicating the high regard in which the Kasamori Kannon Hall was held at the time. However, during repairs in 1960 (Showa 35), inscriptions dating from the Tensho and Bunroku periods were discovered, revealing that the existing building dates back to the Momoyama period (late 16th century).
Nevertheless, this building boasts a history of over 400 years, was designated a “National Treasure” in 1908 (Meiji 41), and later became a “Nationally Designated Important Cultural Property” with the enactment of the Cultural Properties Protection Law in 1950 (Showa 25).
The 31st Temple of the Bando Thirty-Three Kannon Pilgrimage
Kasamori-ji Temple, as the 31st temple of the Bando Thirty-Three Kannon Pilgrimage, has long been visited by many pilgrims. The Bando Thirty-Three Kannon Pilgrimage is a pilgrimage route that visits 33 temples dedicated to Kannon Bodhisattva, mainly in the Kanto region, and is said to have been established by Minamoto no Yoritomo during the Heian period. The principal image, the Eleven-Faced Kannon Bodhisattva, is revered as a Kannon who relieves people’s suffering and grants their wishes.
What is Japan’s Only Four-Sided Suspended Construction?
Structural Characteristics of the Four-Sided Suspended Construction
The most distinctive feature of Kasamori Kannon-do is its “four-sided suspended construction,” a unique architectural style in Japan. The term “Shiho-kakezukuri” refers to a construction method where a building is erected on a massive rock at the mountaintop, supported on all four sides by long pillars. While the “kakezukuri” (suspended construction) of Kiyomizu-dera Temple’s stage is known for supporting only one side with pillars, the Kasamori Kannon-do Hall requires more complex and advanced techniques to support all four sides.
The Kannon-do Hall is supported by 61 pillars, and these wooden pillars have supported the building for hundreds of years. Climbing the stairs and walking along the corridors, one is overwhelmed by the magnificent sight of dozens of pillars intertwined. The irregular arrangement of the pillars conforms to the terrain, creating a unique landscape that integrates with the natural rock.
Architectural Techniques and Preservation
The Kasamori Kannon-do Hall, a culmination of Momoyama period architectural techniques, possesses both the durability and beauty of a wooden structure. Regular repairs and preservation work maintain its value as an Important Cultural Property. During a major repair in 1960 (Showa 35), a structural survey was conducted, determining the building’s construction date and carrying out reinforcement work.
The floor of the Kannon Hall is designed as a corridor, allowing visitors to walk around the entire perimeter. From this corridor, you can enjoy magnificent views of the Kasamori-dera Natural Forest and the southern Boso Peninsula. Especially on clear days, you can see the surrounding mountains and distant landscapes, truly making it an experience worthy of being called a “temple in the sky.”
Kasamori-dera Natural Forest and Highlights of the Temple Grounds
Natural Forest Designated as a Natural Monument
The area surrounding Kasamori-dera Temple is designated as a natural monument of Chiba Prefecture, known as the “Kasamori-dera Natural Forest.” Evergreen broad-leaved trees such as Castanopsis sieboldii, Machilus thunbergii, and fir grow abundantly, preserving a natural environment close to a primeval forest. Because this forest has been protected as an object of worship since ancient times, precious natural areas untouched by human hands remain.
Walking along the approach to the temple, you can feel a mystical atmosphere surrounded by giant trees. The Kannon Hall, built as if blending with the forest, embodies the beauty of Japanese architecture, where nature and man-made structures harmonize. The natural forest, which displays different expressions depending on the season, offers new discoveries with each visit: the fresh green of spring, the deep green of summer, the vibrant autumn foliage, and the tranquility of winter.
Approach and Stairs
The approach to Kasamori Kannon is part of the Metropolitan Area Nature Trail and is a popular course for hikers and walkers. Upon entering the temple grounds, a staircase leading to the Kannon Hall at the mountaintop appears. While some parts of the staircase are steep, it’s possible to take breaks along the way.
As you climb the stairs, the view gradually opens up, and the surrounding scenery changes, creating a pilgrimage-like experience of moving from the secular world to a sacred place. Small shrines and stone Buddha statues are placed along the staircase, watching over the worshippers.
Other Highlights on the Temple Grounds
Besides the Kannon Hall, there are several other points of interest on the grounds of Kasamori Temple. Upon passing through the Niomon Gate, Nio statues are positioned on either side, welcoming worshippers. Furthermore, the temple grounds also house a statue of Kannon known as the “Child-Granting Kannon,” attracting visitors praying for children.
After purifying oneself at the water basin, visitors can enjoy the seasonal flowers along the path to the main hall. In spring, plum and cherry blossoms bloom in profusion, making it a famous spot for “spring flowers (plum and cherry blossoms).” The tranquil atmosphere of the temple grounds, combined with the seasonal beauty of nature, is another charm of Kasamori-ji Temple.
Kasamori Kannon as a Power Spot
The Sunrise Ley Line
Kasamori Kannon is also attracting attention as a power spot located on the sunrise ley line. A ley line is a configuration where sacred sites, shrines, and temples are aligned in a straight line, and there is a theory that this was intentionally arranged since ancient times. Kasamori Kannon is said to be aligned with other sacred sites in the direction of the sunrise on the spring and autumn equinoxes, and is considered a place where special energy gathers.
Kannon Worship and Benefits
Kasamori Kannon, whose principal deity is the Eleven-Faced Kannon Bodhisattva, is believed to offer various benefits. Kannon Bodhisattva is a symbol of compassion and is worshipped as a being who hears people’s wishes and relieves them from suffering. Many visitors come to pray for family safety, recovery from illness, safe childbirth, and academic success, and there is a constant stream of pilgrims seeking Goshuin (temple stamps).
The location of the Kannon Hall, built on a large rock, is also considered to have spiritual significance as a place where the energy of the earth gathers. Many visitors say that by calming their minds in the tranquil environment surrounded by forest and offering prayers to Kannon, they can receive mental and physical refreshment and healing.
