It is a historic ancient temple founded and restored during the Kamakura and Muromachi periods, and it houses many valuable cultural assets, including its main gate, a nationally designated Important Cultural Property.
The temple is located in a scenic area near Tenryukyo Gorge and is known as a famous spot for flowers such as wisteria, peonies, and rhododendrons. Many worshippers and tourists visit, especially from spring to early summer.
History of Kaizenji Temple
Founded in the Kamakura Period
There are several legends regarding the founding of Kaizenji Temple. According to temple tradition, the temple was founded during the Kamakura period by Shijo Yorimoto, who entered the Igara Manor. Another record suggests it was founded by the Ema clan, a branch of the Hojo clan.
Igara Manor was a manor that existed in the area around present-day Iida City from the Kamakura to Muromachi periods, and was the political and economic center of the region. The fact that a samurai family appointed as local administrators built a temple in this area demonstrates the deep connection between the samurai class and Buddhism at that time.
Restoration in Kenmu 2 (1335)
The most important turning point in the history of Kaizenji Temple was its restoration in Kenmu 2 (1335). Ogasawara Sadamune, who became the governor of Shinano Province, became the founder, and he invited Seisetsu Shocho (Daikan Zenji), a high-ranking monk from Yuan Dynasty China, from Kenninji Temple in Kyoto to be the founding abbot.
Seisetsu Shōchō was a high-ranking Zen monk who introduced the Rinzai school of Zen Buddhism from China to Japan. He was also active at Engaku-ji and Kenchō-ji temples in Kamakura and was considered the foremost Zen monk of his time. By welcoming him as its founding abbot, Kaizen-ji Temple established itself as a central Rinzai Zen temple in southern Shinano Province.
The temple’s founder, Ema-ni Jōgen, was the wife of the Ema clan, the local lords of Igarashi Manor. She donated temple lands, solidifying Kaizen-ji’s foundation. With the patronage of Ogasawara Sadamune and the religious authority of Seisetsu Shōchō, Kaizen-ji rapidly developed.
Prosperity during the Muromachi Period
In 1338 (Ryakuō 1), Kaizen-ji was ranked as one of the “Various Mountains” in the Five Mountains and Ten Temples system. This meant it was officially recognized as a temple of a status second only to the Kyoto Five Mountains and Kamakura Five Mountains.
Furthermore, in 1427 (Ōei 34), it attained the status of one of the “Ten Temples.” The Ten Satsuma were a group of temples with a high status second only to the Five Mountains, and only a limited number of temples in Japan were able to attain this status. Kaizenji’s inclusion among the Ten Satsuma demonstrates its importance as a religious and cultural center of southern Shinano during the Muromachi period.
During this period, Kaizenji functioned as a training ground for many monks and played a significant role in the cultural development of the surrounding area. The rigorous training system unique to Zen temples and the advanced culture introduced from China profoundly influenced the spiritual culture of this region.
From the Sengoku Period to the Edo Period
Records indicate that the main hall was built during the Tenbun era (1532-1555). Even during the turbulent Sengoku period, Kaizenji continued to function as a center of faith in the region.
In the Edo period, Kaizenji clearly belonged to the Myoshinji branch of the Rinzai school of Zen Buddhism, and has continued to uphold its lineage to this day. Throughout the Edo period, it continued its activities as a temple with the support of influential local figures and parishioners. ### Modern and Contemporary Period
Despite the impact of the anti-Buddhist movement during the Meiji era, Kaizenji Temple successfully preserved its valuable cultural assets. In the Showa era, its historical value was officially recognized, with the temple gate being designated a National Important Cultural Property.
Currently, in addition to its role as a religious facility, it is also a popular tourist destination with historical buildings and beautiful gardens.
Cultural Assets of Kaizenji Temple
Nationally Designated Important Cultural Property: Temple Gate
The most important cultural asset at Kaizenji Temple is the temple gate, designated as a National Important Cultural Property. This gate is a valuable structure that preserves the architectural style of the early Muromachi period, strongly retaining the characteristics of Zen Buddhist style (Tang style).
Architectural Style of the Temple Gate
The temple gate is a three-bay, single-entrance gatehouse with a hipped roof covered in cypress bark shingles. The temple gate exhibits distinctive Zen Buddhist architectural details throughout, particularly in its structural elements and column placement, reflecting the advanced architectural techniques of the time.
All columns are cylindrical, and a balustrade surrounds the upper level. The deep eaves and powerful, curving roof embody the aesthetic sensibilities of Zen Buddhist architecture during the Muromachi period.
Historical Value
While there are various theories regarding the construction date of the temple gate, its stylistic characteristics suggest it dates from the late 14th to early 15th century. As a representative example of medieval Zen Buddhist architecture remaining in the southern Shinano region, it holds an extremely important position in architectural history.
Medieval gatehouses remaining in Nagano Prefecture are limited in number, and the Kaizenji Temple gate is remarkably well-preserved, making it a valuable resource for understanding the architectural techniques and aesthetic sensibilities of the time.
Other Cultural Properties
Besides the temple gate, Kaizenji Temple possesses many other cultural properties. The main hall, rebuilt during the Edo period, exhibits a simple yet powerful architectural style characteristic of Zen Buddhist temples.
The temple houses treasures such as calligraphy and paintings associated with Seisetsu Shocho, calligraphy by successive chief priests, Buddhist statues, and Buddhist implements, some of which are occasionally displayed on special occasions.
Highlights of Kaizenji Temple
The Beauty of the Wisteria Trellis
Kaizenji Temple is widely known as the “Wisteria Temple,” and its wisteria trellis is one of the most famous wisteria viewing spots in southern Shinshu. The sight of purple and white wisteria blossoms hanging from ancient trees, some hundreds of years old, is breathtaking.
Best Time to See
The best time to see the wisteria is usually from late April to early May, around Golden Week. While this may vary depending on weather conditions, during this time, countless wisteria flower clusters, some over a meter long, hang down, filling the temple grounds with a sweet fragrance.
The sight of purple and white wisteria blooming simultaneously is truly a work of art created by nature. Walking beneath the wisteria trellis, you can experience a fantastical space created by the purple and white gradient above and the sunlight filtering through the trees.
Peony Garden
Within the grounds of Kaizenji Temple is a magnificent peony garden, where colorful peonies bloom in abundance during the spring. Various varieties of peonies—red, white, pink, yellow, and more—are planted, allowing visitors to enjoy the magnificent beauty of the peony, often called the “king of flowers.”
The best time to see the peonies is from mid-April to early May, often coinciding with the wisteria blooming season, allowing visitors to enjoy both at the same time. The combination of the large-flowered peonies and the elegantly drooping wisteria captivates visitors.
Rhododendron Clusters
Another highlight of Kaizenji Temple is the rhododendrons. Planted throughout the temple grounds, the rhododendrons bloom with vibrant flowers from late April to May.
Rhododendrons are naturally alpine plants, but at Kaizenji Temple, they are carefully cultivated to thrive even in lowland areas. The sight of rhododendrons in a variety of colors—pink, white, reddish-purple, and more—blooming against the backdrop of the temple gate and main hall is truly exceptional.
Seasonal Expressions
While Kaizenji Temple is particularly famous for its spring flowers, it offers different charms throughout the four seasons.
Spring (March-May): Starting with plum and cherry blossoms, followed by peonies, wisteria, and rhododendrons, flowers bloom one after another. This is the most vibrant season.
Summer (June-August): The fresh greenery is beautiful, and the temple grounds are enveloped in deep green. You can feel the tranquil atmosphere characteristic of a Zen temple.
Autumn (September-November): The autumn leaves color the temple grounds, and the maple trees around the temple gate are particularly magnificent. In the crisp autumn air, the contrast between the historical buildings and the autumn foliage creates a beautiful landscape.
Winter (December-February): The snow-covered temple gate and main hall have a sumi-e (ink painting)-like quality, embodying the serene world of Zen.

Differences from Other Kaizenji Temples
There are several temples named “Kaizenji” throughout Japan. To avoid confusion, we will introduce the main Kaizenji temples.
Kaizenji Temple in Nagano City
There is also a Shingon Buddhist temple called Kaizenji in Nagano City. This temple is located at the northern foot of Maizuru Mountain and was relocated by Sanada Nobuyuki in 1624 (Kanei 1) along with Shiratori Shrine. It functioned as the head temple of Shiratori Shrine.
While Kaizenji Temple in Iida City belongs to the Myoshinji branch of the Rinzai school of Zen Buddhism, Kaizenji Temple in Nagano City belongs to the Shingon school, and their sects and founding histories are completely different.
Kaizenji Temple in Honjo City, Saitama Prefecture
There is also a Rinzai Zen temple called Kaizenji in Honjo City, Saitama Prefecture. This temple was founded in 1591 (Tensho 19) by Ogasawara Nobumine, the lord of Honjo Castle, and was established as the Ogasawara family’s ancestral temple. It is one of the seven temples on the Musashi Honjo Seven Lucky Gods pilgrimage, and Hotei (the god of happiness) is enshrined here.
Interestingly, both Kaizenji Temple in Iida City and Kaizenji Temple in Honjo City have deep connections to the Ogasawara clan and belong to the same Rinzai school. This suggests that the Ogasawara clan established Kaizenji temples in various locations. ## Research and Literature on Kaizenji Temple
