Reikanji Temple is a temple of the Myoshinji school of the Rinzai tradition of Zen Buddhism, located in Higashiyama, Nakano City, Nagano Prefecture. Its mountain name is Entsuzan, and its head temple is Myoshinji Temple in Kyoto, one of Japan’s most important Rinzai Zen temples.
The temple’s principal Buddhist image is Shō Kannon, or the Sacred Kannon Bodhisattva. Revered by local residents for centuries, Reikanji remains a quiet place of Buddhist worship surrounded by the mountains of northern Nagano.
Reikanji is traditionally said to have been founded in 1324, during the Kamakura period, by the distinguished Rinzai Zen monk Kanzan Egen, also known as Musō Daishi.
Kanzan Egen is said to have established the temple to pray for the spiritual well-being of his father, Takanashi Takaie, who belonged to the powerful Takanashi clan.
During the medieval period, the Takanashi clan was an influential warrior family that controlled areas of Takai and Mizuchi districts in Shinano Province, the historical name for present-day Nagano Prefecture. The clan’s patronage contributed to the development of Reikanji, whose original temple grounds are said to have covered approximately 16,000 tsubo, an area equivalent to roughly 53,000 square meters.
The fortunes of Reikanji changed dramatically during the Sengoku period, a turbulent era of civil warfare in Japan. The Takanashi clan became an ally of the powerful warlord Uesugi Kenshin and participated in the Battles of Kawanakajima, including the major conflict of 1561.
During the fighting, Reikanji was caught in the flames of war and was destroyed. The temple subsequently remained abandoned for a long period.
The founder of Reikanji, Kanzan Egen, later became widely recognized as the founder of the Myoshinji school of Rinzai Zen Buddhism. His teachings and legacy had a profound influence on Zen temples throughout Japan.
For this reason, Reikanji is regarded as one of the places connected with the early life and spiritual legacy of Kanzan Egen. The temple serves as an important reminder of the historical development of the Myoshinji tradition of Zen.
After centuries had passed, Reikanji was revived in its present location in Higashiyama, Nakano City, in 1937 to commemorate the legacy of Kanzan Egen.
The revival began after Tōkai Tōtatsu Zenji, then head of Myoshinji Temple in Kyoto, visited Nakano in 1933. He was deeply impressed by the sites associated with Kanzan Egen and encouraged efforts to restore the temple.
In 1935, a monument commemorating the birthplace of Musō Daishi was erected, and temple buildings were gradually prepared. Reikanji was formally revived in 1937 and has continued to welcome visitors and worshippers ever since.
The Main Hall enshrines the Sacred Kannon Bodhisattva, the temple’s principal image. The quiet interior conveys a sense of dignity and serenity, and the hall remains the central place of worship for visitors and local devotees.
The Founder’s Hall houses an image of Kanzan Egen, also known as Musō Daishi, the monk associated with the founding of Reikanji. The hall preserves the memory of his teachings and spiritual legacy.
Reikanji is counted among the Five Sacred Sites associated with Musō Daishi. Together with the other sites, it traces important stages in his life and spiritual journey.
Nakano Takanashi Ancient Castle: Traditionally regarded as his birthplace.
Kenchōji Temple in Kamakura: Associated with his period of Buddhist training.
Daitokuji Temple in Kyoto: Another site associated with his training.
Ifuku Village in Gifu Prefecture: Traditionally regarded as a place where his spiritual formation developed.
Myoshinji Temple in Kyoto: Associated with his establishment of the Zen lineage and his posthumous title as a National Teacher.
Reikanji is also regarded as one of the Three Great Sacred Sites associated with Musō Daishi, together with Myoshinji Temple in Kyoto and Shōgenji Temple in Gifu Prefecture. These connections give Reikanji an important place in the spiritual and cultural history of Japanese Zen Buddhism.
In 2002, the first Musō Daishi Birth Festival was held at Reikanji. One of the highlights was a Chigo procession, in which local children dressed in traditional ceremonial clothing took part in a procession to the temple.
Such events provide opportunities for local residents, especially younger generations, to learn about the temple’s history and express respect for Kanzan Egen. Through these activities, Reikanji continues to strengthen its connection with the surrounding community while helping preserve local religious and cultural traditions.

Reikanji Temple stands quietly among the mountains of Nakano City, yet its history is closely connected with one of the most important figures in Japanese Rinzai Zen.
From its foundation in the 14th century and destruction during the era of civil warfare to its revival in the 20th century, the temple has experienced dramatic changes while preserving its connection with Kanzan Egen and the Takanashi clan.
For visitors interested in Japanese Buddhism, Zen culture, medieval history, or the quiet atmosphere of historic temples, Reikanji offers an opportunity to encounter a lesser-known chapter of Nagano’s cultural heritage.
When visiting Nakano City, taking time to explore this peaceful temple and its surrounding landscape provides a chance to experience the history and serenity of northern Nagano away from the region’s better-known tourist destinations.
