History of Seikaiji Temple
Founding and Temple Tradition
According to temple tradition, Seikaiji Temple was founded during the Konin era (810-824) by Kobo Daishi Kukai, with Aizen Myoo as the principal deity. A legend remains that Kukai stopped at this location on his way to visit Atsuta Shrine in Nagoya, built a large mound within the temple grounds, and buried a cast statue of Daishō Kangiten.
During the Jisho era (1177-1181), the current principal deity, a Zenkoji-style Amida Triad, was enshrined, and it is believed that the temple’s form was established during this period.
Changes from the Medieval to the Early Modern Period
From the medieval period onward, Seikaiji Temple developed under the patronage of many influential figures. During the Kamakura period, Hojo Tokiyori and, during the Muromachi period, Ashikaga Takauji were patrons of the temple, contributing to its prosperity.
From the Sengoku period to the early Edo period, the temple received protection from warlords who ruled the Owari region, including Asano Nagamasa, Matsudaira Tadayoshi (fourth son of Tokugawa Ieyasu), and Tokugawa Yoshinao (first lord of the Owari Tokugawa family). Its relationship with the Owari Tokugawa family was particularly deep, receiving support throughout the Edo period in the form of land security and building repairs.
Developments since the Modern Era
Despite the impact of the anti-Buddhist movement after the Meiji Restoration, Shokaiji Temple successfully preserved its valuable cultural assets. In 1954, the main hall, pagoda, and multi-storied pagoda were designated as important national cultural properties, and the temple came to be recognized as an important temple from the perspective of cultural property preservation.
In 1992 (Heisei 4), the city of Inazawa developed the Otsuka Seikaiji Historical Park, opening approximately 5,000 square meters of land, including the temple grounds, to the public as a park. This created a unique space where a historical temple and a place of relaxation for citizens are fused together.
Cultural Properties of Seikaiji Temple
Nationally Designated Important Cultural Property
Main Hall
The main hall of Seikaiji Temple is a building rebuilt during the Keian era (1648-1652) and was designated a National Important Cultural Property in 1954 (Showa 29). It is a magnificent building with a five-bay by five-bay hip-and-gable roof and tiled roof.
While the exterior is a reconstruction from the early Edo period, the interior’s altar, raigo-mawari (a surrounding area for welcoming the deceased), and the majority of the ceiling reuse materials from the medieval period, making it a valuable historical structure that conveys the architectural style of the Muromachi period. The main image, a Zenkoji-style Amida Triad, is enshrined in the inner sanctuary, creating a solemn atmosphere. #### Pagoda
The pagoda of Shōkai-ji Temple, like the main hall, is a stone pagoda designated as an Important Cultural Property in 1954. Made of granite and standing approximately 3 meters tall, it is estimated to have been constructed between the late Kamakura period and the Nanboku-chō period.
It is a typical pagoda structure, consisting of a base, body, roof, and finial, with intricate carvings on each part. In particular, Sanskrit characters are inscribed on the body, suggesting it was built as an object of esoteric Buddhist worship. It is in excellent condition and is highly regarded as a fine example of medieval stone art.
Multi-storied Pagoda
The multi-storied pagoda of Shōkai-ji Temple is a strikingly elegant structure within the temple grounds. It was designated an Important Cultural Property in 1954. It is estimated to have been built in the mid-Muromachi period and features a three-bay multi-storied pagoda structure with a shingle roof.
The pagoda features the distinctive form of a multi-storied pagoda, with a square lower level and a circular upper level, and the details of the brackets and carvings are magnificent. Its overall proportions are beautiful, and it is known as an outstanding example of Japanese multi-storied pagoda architecture. Located in front of the main hall, it plays an important role in the landscape of the temple grounds.

Shōkaiji Temple as a Hydrangea Temple
Hydrangeas at Ōtsuka Shōkaiji Historical Park
Shōkaiji Temple became widely known as a “hydrangea temple” due to the large hydrangea garden planted in the adjacent Ōtsuka Shōkaiji Historical Park. The sight of approximately 10,000 hydrangea plants of about 90 varieties blooming all at once during the rainy season in June is truly spectacular.
The park is planted with a diverse range of hydrangea varieties, from traditional Japanese varieties to Western hydrangeas, lacecap hydrangeas, and mountain hydrangeas, creating a vibrant display of blue, purple, pink, and white flowers. Because the blooming periods vary slightly depending on the variety, visitors can enjoy the flowers for an extended period, from early to late June.

The hydrangeas with the pagoda in the background are a particularly excellent photo spot.
Seasonal Charms
