Chorakuji Temple, formally known as Obasutezan Hoko-in Chorakuji, is a historic Tendai Buddhist temple in Chikuma City, Nagano Prefecture. Dedicated to the sacred image of Sho-Kanzeon Bosatsu, or the Bodhisattva Kannon, the temple is the 14th temple on the Shinano Thirty-Three Kannon Pilgrimage.
Built on the slopes of Mt. Obasute, Chorakuji offers sweeping views across the Nagano Basin, traditionally known as the Zenkoji Plain. For centuries, the area has been celebrated as one of Japan’s great places for viewing the moon. Here, religion, literature, landscape, and seasonal beauty come together to create a place where visitors can experience an important aspect of traditional Japanese aesthetics.
Chorakuji stands on the hillside behind Obasute Station on the JR Shinonoi Line. From the temple grounds, visitors can look across terraced rice fields toward the surrounding mountains and the broad Nagano Basin. After sunset, the landscape takes on another character as the moon rises above the rice terraces.
The surrounding area is famous for Obasute (Tagoto-no-Tsuki), a cultural landscape designated a National Place of Scenic Beauty. The expression Tagoto-no-Tsuki, literally “the moon in every rice paddy,” refers to the enchanting sight of the moon reflected in numerous small rice paddies. This landscape has inspired poets and artists for centuries.
The temple’s mountain name, Obasutezan, preserves the ancient name of the mountain, which has long been associated with legends and classical Japanese poetry. The name Choraku can be understood as expressing a wish for people to find lasting peace and happiness through the teachings of Buddhism.
The exact date when Chorakuji was founded is unknown. Historical sources from the Edo period, including Chikuma no Masago, compiled in 1753, and the late-Edo guidebook Zenkoji-michi Meisho Zue, describe the temple as a subsidiary temple of Takemizuwake Shrine in Yawata, which at the time had a Buddhist temple complex known as Sarashina Hachiman Jinguji.
This suggests that Chorakuji may originally have been a small hermitage or monks’ residence under the administration of the shrine’s Buddhist institution. It may have served as a place for ascetic training in the surrounding mountains, a retreat for elderly or retired monks, or a quiet residence for important visitors.
During the early Meiji period, the government’s policy of separating Buddhism and Shinto led to major changes in religious institutions throughout Japan. Chorakuji temporarily became unoccupied, and many of its historical records were lost. As a result, much of the temple’s early history remains uncertain.
The history of Mt. Obasute itself, however, reaches much further back. By the 10th century, the mountain was already known as a scenic place associated with moon viewing and poetry. Since the Heian period, Obasute has held a special place in Japanese literature and the cultural imagination.
An illustrated manuscript known as the Chorakuji Engi, believed to date from the Edo period and now held by the Nagano City Museum, contains a mythological account involving Okuyama-hime-no-Mikoto, Konohanasakuya-hime, and deities associated with the Suwa region.
Although these stories are legendary rather than straightforward historical records, they reflect the traditional shinbutsu-shugo culture of Japan, in which Buddhist and Shinto beliefs were closely intertwined. Chorakuji’s history is therefore deeply connected not only with Buddhism but also with the local religious traditions of the surrounding mountains and villages.
Chorakuji’s greatest cultural distinction lies in its connection with literature and the celebrated moon of Obasute. Poems and haiku inscriptions can be found throughout the grounds, providing visitors with a direct connection to the writers who came here in earlier centuries.
In 1688, during the journey that became known as Sarashina Kiko, the famous haiku poet Matsuo Basho visited Mt. Obasute. He composed the well-known verse:
“Omokage ya / oba hitori naku / tsuki no tomo”
The poem evokes the image of a solitary elderly woman beneath the moon, bringing together the legendary story of Obasute and the quiet beauty of moonlight. The verse is known for its deep emotional resonance and lingering sense of solitude.
The monument known as Omokage-zuka, or the Basho Memorial Mound, was erected in 1769, more than 80 years after Basho’s visit, by the haiku poet Kasha Hakuhaku.
The famous haiku poet Kobayashi Issa is said to have visited Chorakuji at least four times. The celebrated surveyor Ino Tadataka also visited the area in 1814. During his stay, he recorded 13 poems dating from earlier periods in his diary.
These visits demonstrate that Chorakuji was more than a religious site. Its exceptional scenery made it a place of literary inspiration and scholarly interest, attracting visitors who wished to experience the landscape celebrated in classical poetry.
The present Main Hall and Kuri, or priest’s residence and kitchen complex, are traditionally said to have been rebuilt in 1834. Architectural analysis, however, suggests that the buildings may date from the Bunka and Bunsei periods, from 1804 to 1829. Their restrained design preserves the atmosphere of late-Edo-period Buddhist architecture.
The Kangetsuden, or Moon-Viewing Hall, stands beside the Main Hall. A dedication plaque dated 1864 remains at the building, suggesting that it was constructed around that time. The hall underwent conservation work in 2007 and continues to preserve the atmosphere of the traditional moon-viewing culture for which the temple is famous.
Above the Omokage-zuka stands the Tsukimido, another pavilion dedicated to viewing the moon. It is thought to have been built around the same period as the Main Hall and was conserved in 2003.
From this elevated position, the moon appears above the broad Nagano Basin, while the terraced fields below create a landscape that has long been regarded as one of the finest moon-viewing scenes in Obasute.
The Kannondo, or Kannon Hall, stands higher on the temple grounds. Although traditionally believed to have been rebuilt in 1691, architectural details such as the decorative carving of the beams suggest a later reconstruction during the Horeki and Meiwa periods, from 1751 to 1771. Conservation work was carried out in 2004.
One of the most striking features of the temple grounds is Obaishi Rock, also known as Oba-iwa. This enormous natural rock measures approximately 15 meters high and about 25 meters in both width and depth.
From the top of the rock, visitors can enjoy a magnificent panorama of the Nagano Basin. Under a clear night sky, the view becomes especially atmospheric as the moon rises over the surrounding mountains and rice terraces.
The Edo-period travel writer Sugawara Masumi left illustrations showing people climbing this rock to enjoy the moon. Traditionally, the rock itself has been associated with the legendary Mt. Obasute described in Japanese folklore.
Obasute (Tagoto-no-Tsuki) is designated as a National Place of Scenic Beauty. While the phrase “moon in every rice paddy” is commonly used to describe the moon reflected across the area’s terraced fields, the cultural-property designation specifically refers to the moonlit scenery of Shijuhachimai-da, a group of 48 rice paddies historically associated with Chorakuji.
The paddies were also known as Tsukimi-da, or “moon-viewing fields,” and Tsukiyo-da, or “moonlit fields.” The area became a setting for poetry gatherings held around the autumn full moon.
According to tradition, selected groups were permitted to fill the rice paddies with water shortly before the autumn harvest, construct viewing platforms, and hold poetry gatherings while watching the moon reflected in the water. These gatherings connected agriculture with poetry, seasonal rituals, and the refined culture of moon viewing.
References to Tagoto-no-Tsuki can be found in historical sources, including a prayer document dedicated by Uesugi Kenshin to Takemizuwake Shrine. The expression also appears in the traditional Noh and kyogen repertoire, including Tokusa, suggesting that the fame of the landscape had spread widely by at least the Muromachi period.
The last known occasion on which this traditional moon-viewing event was actually held is said to have been in 1927.
Although moonlight is the defining feature of Chorakuji, the temple is beautiful throughout the year. In spring, cherry blossoms add soft color to the historic grounds, while autumn brings brilliant foliage to the surrounding trees.
The combination of flowers and changing leaves, historic temple buildings, terraced rice fields, and the distant mountains of the Zenkoji Plain creates a landscape that changes dramatically with the seasons.
The temple grounds are home to a large katsura tree, designated as a Chikuma City Natural Monument. Estimates of its age vary among sources, but it is said to be more than 500 years old, with some traditions placing its age at between 800 and 1,000 years.
Standing quietly within the temple grounds, this ancient tree is a fitting symbol of Chorakuji, which has preserved the spiritual and cultural atmosphere of Obasute across generations.
Chorakuji is both a place of Buddhist worship and one of Japan’s most evocative landscapes for experiencing the traditional culture of moon viewing. Walking through the temple grounds, visitors encounter historic buildings, literary monuments, ancient trees, and sweeping views of the terraced fields below.
The temple is particularly meaningful for travelers interested in Japanese literature and aesthetics. The poems of Basho, the legends of Obasute, the seasonal landscape, and the tradition of Tagoto-no-Tsuki all reveal how deeply nature has been woven into Japanese cultural expression.
Despite being close to Obasute Station, the temple grounds retain a peaceful atmosphere. Whether visited during cherry blossom season, beneath autumn foliage, or on a clear evening when the moon rises over the rice terraces, Chorakuji offers an opportunity to slow down and experience the beauty that generations of Japanese poets and travelers have admired.
