Chorakuji Temple is a historic Tendai Buddhist temple located in Serada, Ota City, Gunma Prefecture. Its mountain name is Seradayama, and the principal object of worship is Shaka Nyorai, the Buddha Shakyamuni.
The temple occupies an expansive grounds of considerable historical importance. It stands next to Serada Toshogu Shrine, which has strong connections to the Tokugawa family. The surrounding area is also part of the Nitta-no-sho Historic Sites, a nationally designated historic site associated with the medieval Nitta clan and its warrior stronghold.
Founded during the Kamakura period, Chorakuji became renowned as one of the places where Zen culture developed in eastern Japan. At its height, it was a major temple where numerous scholarly monks gathered for study and training. Today, many historic buildings and cultural properties remain on the grounds, preserving the history of the temple from the medieval period through the early modern era.
Chorakuji was founded in 1221 by Tokugawa (Nitta) Yoshisue, the fourth son of Nitta Yoshishige, who is regarded as an ancestor of the Tokugawa family.
For the founding priest, Yoshisue invited Zen Master Eicho, a distinguished disciple of Eisai, the monk traditionally regarded as the founder of the Rinzai school of Zen Buddhism in Japan. The temple was originally established as a Rinzai Zen temple.
Eicho was highly respected for his learning and virtue, and monks from throughout Japan came to Chorakuji to study under him. Numerous subsidiary temples, known as tatchu, were established within the temple complex, and it is said that around 500 scholarly monks were studying and training there at any given time.
Chorakuji thus developed into an important center of Zen practice in eastern Japan, while Serada became a sought-after destination for monks seeking religious training and learning.
From the Kamakura period through the Muromachi period, Chorakuji prospered under the patronage of the Nitta and Ashikaga clans. During the early Muromachi period, it became one of the Ten Temples of Kanto within the Gozan Jissatsu system, a ranking system established by the shogunate for major Zen temples.
At the time, the extensive temple grounds were filled with impressive buildings and served as an important center of Buddhist learning and training in the Kanto region.
However, as the influence of the Nitta clan declined, the temple gradually lost its former power and many of its buildings fell into disrepair.
Chorakuji experienced a major revival after the beginning of the Edo period. When Tokugawa Ieyasu entered the Kanto region, he placed particular importance on the temple because of its connection with his reputed ancestor, Tokugawa Yoshisue.
Ieyasu appointed the eminent Buddhist monk Tenkai as chief priest and ordered him to restore the temple. Tenkai renovated the grounds, rebuilt structures that had fallen into ruin, and converted Chorakuji from the Rinzai school to the Tendai school of Buddhism.
Under the protection of the Tokugawa shogunate, the temple was granted an estate producing 100 koku of rice and was eventually restored as a major temple with around 700 affiliated temples.
During this period, some structures associated with Nikko Toshogu Shrine were also relocated to Chorakuji. The temple consequently flourished as an important religious institution closely connected with the Tokugawa family.
The present Main Hall was rebuilt in 2005 through donations from parishioners and supporters. It was constructed using traditional techniques practiced by Japanese temple carpenters.
The hall enshrines a Buddhist triad consisting of Shaka Nyorai, Monju Bosatsu, and Fugen Bosatsu. These statues are traditionally said to have been donated by Tokugawa Iemitsu, the third shogun of the Tokugawa shogunate, and form the spiritual center of the temple.
Sanbutsudo Hall is traditionally said to date back to the temple’s foundation in 1221. The present structure is based on a building reconstructed by Tokugawa Iemitsu during the Edo period.
Inside are three monumental wooden Buddhist statues, each standing more than 3 meters tall. From right to left, they represent Shaka Nyorai, Amida Nyorai, and Miroku Bosatsu.
The three figures symbolize the past, present, and future, respectively. Their imposing scale and solemn presence make them one of the highlights of a visit to Chorakuji.
The Imperial Messenger Gate was constructed in connection with the relocation of buildings from the Toshogu shrine established by Tokugawa Hidetada, the second Tokugawa shogun.
This magnificent four-legged gate features copper roofing and vermilion lacquer. It was opened only when official messengers of the shogunate or imperial court visited the temple, or when a new chief priest formally entered the temple grounds. For this reason, it became known as the “Never-Opened Gate.”
The Taiko Gate, also known as the Drum Tower, once housed a large drum used to announce temple ceremonies and mark the hours of the day.
Although the drum itself is no longer preserved, the structure remains an important architectural reminder of the temple’s long history and has been designated an Important Cultural Property of Gunma Prefecture.
A stone pagoda stands on the summit of Monjuyama. It is an important example of Japanese stone craftsmanship from the Kamakura period.
An inscription dated 1276 remains on its base. The pagoda is believed to have been erected as a memorial monument for Tokugawa Yoshisue, the founder of Chorakuji.
The temple grounds include a beautiful lotus pond known as the Shinji Pond because its shape resembles the Japanese character shin, meaning “heart” or “mind.”
A graceful stone arch bridge called Togetsukyo Bridge spans the center of the pond, creating a particularly picturesque scene within the temple grounds.
The Founder’s Hall enshrines an image of Zen Master Eicho, the monk who established Chorakuji’s religious tradition. The hall preserves the memory of the temple’s foundation and early history.
It also houses statues of Tokugawa Yoshisue and his wife, as well as a statue of Grand Priest Tenkai. These images reflect the close historical relationship between Chorakuji and the Tokugawa family.
One of the more unusual features of Chorakuji is a mysterious stone known as the “Cow Stone.”
According to legend, when Zen Master Eicho first came to this area, the cow carrying his belongings suddenly sat down in front of what is now the Founder’s Hall and refused to move. The cow is said to have eventually transformed into stone.
Local tradition holds that if visitors sit on the Cow Stone and make a wish, the cow will carry that wish to the Buddhist realm. In recent years, the stone has also become known as a place where people pray for the blessing of children.
The grounds of Chorakuji form an important part of the Nitta-no-sho Historic Sites, an area associated with the Nitta clan, a prominent medieval warrior family.
The expansive temple grounds contain groups of medieval stone monuments as well as ancient burial mounds, making the site valuable for the study of local and Japanese history.
With layers of history extending from the Kamakura period through the Edo period, Chorakuji is more than a religious institution. It is an important cultural heritage site for understanding medieval Japanese history, samurai culture, and the development of Zen Buddhism.
Today, Chorakuji remains one of Ota City’s notable historical attractions. Its peaceful grounds preserve numerous cultural properties and historic landscapes, allowing visitors to experience the atmosphere of a temple shaped by centuries of religious and political history.
Nearby, Serada Toshogu Shrine and numerous sites associated with the origins of the Tokugawa family provide further opportunities for historical exploration.
Chorakuji brings together the history of Kamakura-period Zen culture, the religious and political world of the Muromachi shogunate, and the traditions of the Tokugawa family. A leisurely walk through its grounds offers visitors an opportunity to experience the rich historical heritage of Ota City and eastern Gunma.
