Konpon Chudo is the main hall of Hōshuzan Risshakuji Temple, better known as Yamadera (“Mountain Temple”), in Yamagata City, Yamagata Prefecture. Located at the foot of Mount Hōshu, it is one of the first important buildings visitors encounter when arriving at Yamadera and preserves a long history of Buddhist worship.
The present building was rebuilt in 1356 by Shiba Kanehori, the first lord of Yamagata Castle. It is a dignified irimoya-zukuri structure, featuring a hipped-and-gabled roof and a five-bay by four-bay layout. The building retains the traditional architectural character of an old Tendai Buddhist training hall.
Approximately 60 percent of the building is said to be made from beech wood, making it particularly valuable as one of Japan’s oldest surviving buildings constructed extensively with beech timber. Konpon Chudo is designated a Nationally Designated Important Cultural Property and is one of the structures that symbolizes Yamadera’s long history.
Inside the hall are Buddhist statues including the principal image of Yakushi Nyorai, as well as the Eternal Buddhist Flame, traditionally said to have been passed down for more than 1,200 years.
The official name of Yamadera is Hōshuzan Risshakuji. It is a Tendai Buddhist temple traditionally said to have been founded in 860 by Jikaku Daishi Ennin (794–864) in accordance with an imperial prayer by Emperor Seiwa.
Ennin studied Tendai Buddhist teachings at Enryakuji Temple on Mount Hiei before traveling to China to further his studies. After returning to Japan, he became the third chief abbot, or Tendai Zasu, of the Tendai school and traveled throughout Japan to spread its teachings. He is also known for helping introduce and develop Buddhist culture in northern Japan.
Yamadera developed through its close historical relationship with Enryakuji on Mount Hiei, located in the region of Kyoto and Shiga. The natural landscape of Mount Hōshu itself became a place of religious practice, and numerous halls and Buddhist structures were established throughout the mountain.
The present Konpon Chudo was rebuilt in 1356 by Shiba Kanehori. Its formal irimoya-zukuri, five-bay by four-bay design preserves the architectural character of a traditional Tendai Buddhist training hall.
One of the building’s most notable features is the extensive use of beech wood. It is said to account for approximately 60 percent of the structure, making Konpon Chudo particularly valuable as a historic building constructed primarily from this type of timber.
During a visit to Yamadera, Konpon Chudo is also an important place to pause before beginning the more strenuous mountain ascent. Standing quietly before the hall and taking in its historic appearance can provide a moment to prepare both body and mind for the pilgrimage ahead.
Inside the sanctuary is a seated statue of Yakushi Nyorai, the principal image of Yamadera. The statue is traditionally said to have been carved by Jikaku Daishi Ennin himself and has been an object of devotion for centuries.
Yakushi Nyorai is revered as the Buddha of healing, believed to offer relief from illness and suffering and to bring health and peace. Standing on either side of the principal image are Nikko Bosatsu and Gakko Bosatsu, while the Twelve Heavenly Generals are arranged around them as guardians of Yakushi Nyorai.
The hall also houses a standing statue of Monju Bosatsu, the bodhisattva associated with wisdom, and a standing statue of Bishamonten, one of the Four Heavenly Kings. The Monju Bosatsu statue is traditionally said to have originally been enshrined in Monjudo before being moved to Konpon Chudo following a fire.
The principal statue of Yakushi Nyorai is considered a hidden Buddha and is traditionally said to be revealed to the public only once every 50 years. Because it is normally not visible, visitors can experience its presence through the solemn atmosphere of the hall and the long tradition of worship surrounding it.
One of the most important features of Konpon Chudo is the Eternal Buddhist Flame. Burning quietly in front of a Buddhist altar inside the hall, the flame has become a powerful symbol of Yamadera’s religious tradition.
According to tradition, Jikaku Daishi Ennin brought the flame back from Enryakuji Temple on Mount Hiei. Since then, the sacred flame has been passed down between Yamadera and Enryakuji and carefully maintained over the centuries.
When Enryakuji was burned during the military campaigns of Oda Nobunaga, the tradition says that Yamadera provided a flame to help relight the sacred fire after Enryakuji was rebuilt. In this way, the two temples are said to have preserved their flames by sharing them with one another, maintaining the tradition for more than 1,200 years.
The small flame flickering quietly inside Konpon Chudo symbolizes the deep connection between Yamadera and Enryakuji, as well as the continuity of Buddhist faith across more than a millennium.
Continuing from Konpon Chudo into the mountain, visitors encounter a statue of the celebrated haiku poet Matsuo Bashō (1644–1694) and monuments associated with the famous poem he composed at Yamadera.
In 1689, Bashō visited Yamadera with his disciple Kawai Sora while traveling through northern Japan and the Hokuriku region. Moved by the tranquil scenery and profound silence of the temple grounds, he is said to have composed the following famous haiku:
“Shizukesa ya / Iwa ni shimiiru / Semi no koe”
The poem is commonly translated as “Silence—the sound of cicadas sinking into the rocks.” It was included in Bashō’s celebrated travel work, The Narrow Road to the Deep North (Oku no Hosomichi), and has become inseparably associated with Yamadera.
Walking through the quiet temple grounds and listening to the sounds of nature around the rocky mountain can help visitors imagine the atmosphere that inspired Bashō more than three centuries ago.
Beyond Konpon Chudo, visitors enter the main mountain pilgrimage route and begin the ascent of Mount Hōshu. From the trailhead to Okunoin, the route consists of a total of 1,015 stone steps.
These steps are more than an ordinary mountain path. According to Yamadera’s tradition, each step represents the gradual removal of worldly desires and attachments. As they climb, visitors can leave behind the distractions and worries of everyday life while passing the halls, statues, and unusual rock formations scattered throughout the mountain.
Along the route are numerous highlights, including the Treasure Hall, Hie Shrine, Ubado, Semizuka, Midahora, and Niomon Gate. Further up the mountain, the path continues toward Kaizando, Nokyodo, Godaido, and finally Okunoin.
The entire mountain of Yamadera forms a landscape where nature, Buddhist faith, and history are closely intertwined, with Konpon Chudo serving as an important starting point for the pilgrimage.
Konpon Chudo is located near the entrance to the Yamadera temple grounds and can be reached on foot from Yamadera Station. Although it stands at the foot of the mountain, the surrounding cedar trees and rocky landscape already create the distinctive sense of quiet and sacredness associated with Yamadera.
After viewing the Buddhist statues and the Eternal Buddhist Flame inside the hall, visitors can continue along the route to sites associated with Matsuo Bashō before beginning the long climb up the mountain. This gradual progression provides an opportunity to experience Yamadera’s history and religious traditions step by step.
A historic wooden hall, a hidden image of Yakushi Nyorai, and an Eternal Buddhist Flame said to have been preserved for more than 1,200 years. Konpon Chudo brings together many of the traditions that define Yamadera and can be regarded as an essential starting point for exploring Risshakuji.
