Byodoin Temple is a Soto Zen Buddhist temple located in Miwa, Sakurai City, Nara Prefecture. Its mountain name is Miwasan, and its principal image of worship is the Eleven-Headed Kannon, the bodhisattva of compassion. In the past, Byodoin served as a Buddhist temple associated with Miwa Myojin, now known as Omiwa Jinja, alongside Daigorinji and Joganji. Because of this close connection with the shrine, it was also known as Miwa Bessho, a name reflecting its longstanding importance as a center of religious devotion.
According to tradition, Byodoin was originally founded by Prince Shotoku and later revived by the monk Keien. The history of the temple may extend even further back. The History of Omiwa Town suggests that Omiwadera Hensho-in, an earlier religious institution that preceded Byodoin, may have been established by the Buddhist monk Kobo Daishi Kukai.
One of the oldest surviving written records mentioning the temple is the Miroku Nyorai Kannōshōsō, dated 1236 during the Kamakura period (1185–1333). This document refers to the institution as Miwa Bessho, providing evidence of its established presence by that time.
During the Kamakura period, Byodoin established itself as an important religious institution known as Miwa Bessho. It also served as the bettoji, or Buddhist temple responsible for the administration of religious affairs at Miwa Myojin.
The historical record Daijoin Jisha Zojiki notes that Byodoin was a subordinate temple of Kofukuji in Nara. It also functioned as a center for Shugendo, a Japanese religious tradition combining Buddhist teachings, mountain asceticism, and elements of indigenous spiritual practices.
Although the temple was influenced by Kofukuji, it also maintained close ties with Daigoji. Its religious community had a distinctive structure in which scholars associated with Kofukuji and Zen practitioners connected with Daigoji coexisted. This combination reflected the complex relationships among Buddhist schools and mountain religious traditions in medieval Japan.
During the Edo period (1603–1868), Byodoin gradually moved beyond the direct control of Kofukuji and developed a stronger identity as a Shingon Buddhist temple, while continuing to be influenced by Shugendo. It also served as an naigu, a temple responsible for prayers on behalf of the imperial household, and held an officially recognized estate yielding 80 koku of rice.
Illustrations of the temple complex from the Muromachi period (1336–1573) show the extensive grounds that once spread south of Miwa Myojin. The buildings included the main hall, a hall commemorating the monk Keien, a hall for mountain ascetics, a portrait hall, and a sutra repository. Together, these structures made Byodoin a substantial religious complex closely connected with the worship of Mount Miwa.
One of the temple’s best-known historical stories concerns the samurai lord Shimazu Yoshihiro. After the Battle of Sekigahara in 1600, Yoshihiro and a small group of retainers reportedly fled to Byodoin, where they stayed for 70 days.
According to the story, Yoshihiro borrowed one kanme of silver, approximately four kilograms, from the temple’s head priest to finance his return journey to Satsuma, in present-day Kagoshima Prefecture. He eventually made it home safely. The Shimazu family subsequently showed deep respect for the temple and continued to support it throughout the Edo period, including by funding the construction of a Goma Hall for esoteric Buddhist rituals and donating rice.
The government’s 1868 decree separating Shinto and Buddhism brought a major turning point for Byodoin, as it did for many temples that had been closely associated with Shinto shrines. In 1870, the temple buildings were destroyed, leaving the institution in danger of disappearing entirely.
Local supporters and former temple priests worked to restore the site. Their efforts eventually led to the temple’s revival as a Soto Zen Buddhist institution, allowing its religious traditions to continue despite the upheavals of the Meiji period (1868–1912).
In 1977, Byodoin was reestablished in its present form as Miwasan Byodoin. Restoration has continued since then, and several buildings have been reconstructed. Today, the temple grounds contain the main hall, Fudo Hall, a two-story pagoda, and other structures that preserve an atmosphere of solemnity and devotion.
The main hall, rebuilt in 1987, also serves as a meditation hall for zazen, the seated meditation practiced in Zen Buddhism. It enshrines the Eleven-Headed Kannon and other Buddhist figures, continuing the temple’s longstanding tradition of worship.
Namikiri Hall is dedicated to Namikiri Fudo Myoo, a fierce manifestation of Fudo Myoo associated with overcoming obstacles and spiritual protection. The hall reflects the temple’s historical connections with esoteric Buddhist practices.
The two-story pagoda, also known as Shakado or the Hall of Shakyamuni Buddha, was rebuilt in 2004. Its traditional architecture adds to the character of the restored temple complex.
The bell tower was rebuilt in 1987. Its bell was cast under the guidance of Masahiko Katori, a Japanese metalworker designated a Living National Treasure. The bell represents the continuing importance of traditional craftsmanship and Buddhist ritual at Byodoin.
The Sanmon, or main gate, is said to be the only building on the grounds that survived from before the temple’s modern revival. It provides a tangible link with the site’s earlier history.
An Inari shrine on the grounds enshrines deities associated with Fushimi Inari and Toyokawa Inari. Its presence reflects the long history of interaction between Buddhist temples and Shinto worship in Japan.
Byodoin is located in Miwa, Sakurai City, and can be visited alongside nearby Omiwa Jinja and Mount Miwa. Its history offers a glimpse into the close relationship between Buddhist temples and Shinto shrines that shaped Japanese religious life for centuries.
For travelers exploring the ancient spiritual landscape of the Miwa area, Byodoin provides an opportunity to discover a temple that endured periods of prosperity, destruction, and revival while maintaining its connection with local faith and tradition.
