History of Iwasaki-ji Temple
Founding History
Iwasaki-ji Temple is said to have been founded in 806 (Daido 1) during the early Heian period. This period was a crucial turning point in the history of Japanese Buddhism, coinciding with the time when eminent monks such as Saicho and Kukai brought new forms of Buddhism back from Tang China and established the Tendai and Shingon sects.
While detailed records from the time of its founding are not available, it can be inferred that the temple served as a center of Buddhist faith in the region, attracting the devotion of local residents from an early stage. The existence of Buddhist statues created from the Heian to Kamakura periods suggests that the temple possessed a considerable scale and a strong foundation of faith even at that time.
Changes in Era and the Present
Iwasaki-ji Temple has experienced numerous changes throughout its long history of over 1200 years. It has overcome various difficulties faced by Japanese temples, including the turmoil of the Sengoku period, the control of temples during the Edo period, and the anti-Buddhist movement after the Meiji Restoration, to reach its present state.
Iwasaki-ji Temple, currently a Soto Zen temple, is maintained primarily by local parishioners. Through regular memorial services and annual events, it continues to play a vital role as a spiritual center of the local community.
Group of Buddhist Statues Designated as Prefectural Cultural Properties
The most distinctive feature of Iwasaki-ji Temple is its collection of precious Buddhist statues, designated as Yamaguchi Prefecture Cultural Properties on April 5, 1983 (Showa 58). These statues were created from the mid-Heian period to the early Kamakura period, demonstrating the high level of Buddhist art at that time.
Wooden Standing Statue of the Thousand-Armed Kannon Bodhisattva
The wooden standing statue of the Thousand-Armed Kannon Bodhisattva, the principal image of Iwasaki-ji Temple, is an important Buddhist statue estimated to be from the mid-Heian period. The Thousand-Armed Kannon is a symbol of compassion, said to “save all sentient beings with a thousand hands and a thousand eyes,” and is a particularly popular deity in Kannon worship.
This statue exhibits the gentle and elegant style characteristic of the Heian period, demonstrating the high level of skill of the Buddhist sculptors of that time. The statue is in excellent condition and is a valuable cultural asset that conveys its original appearance.
Wooden Seated Shakyamuni Buddha Statue
Shakyamuni Buddha is a Buddhist statue representing Gautama Siddhartha (Shakyamuni Buddha), the founder of Buddhism. The wooden seated Shakyamuni Buddha statue owned by Iwasaki-ji Temple is believed to have been created between the Heian and early Kamakura periods, and is depicted in a seated form with the meditation mudra.
Shakyamuni Buddha statues hold an important position as the fundamental Buddha in Buddhist temples, and this statue has been an object of worship for many years. The meticulous finishing of the carving details demonstrates the faith and high level of skill of the Buddhist sculptor of the time.
Wooden Seated Amida Buddha Statue
Amida Buddha, as the principal deity of the Western Pure Land, is the most widely worshipped Buddha in Japanese Buddhism from the Heian period onward. The wooden seated statue of Amida Buddha at Iwasaki-ji Temple is depicted in a seated form with the mudra of meditation, characterized by its serene expression and well-proportioned physique.
From the late Heian period to the early Kamakura period, Pure Land Buddhism spread widely from the aristocracy to the common people. It is believed that this Amida Buddha statue was created and worshipped within this historical context.
Regarding the Public Display of Hidden Buddha Images
Important: The three wooden statues—the standing statue of the Thousand-Armed Kannon Bodhisattva, the seated statue of the Shakyamuni Buddha, and the seated statue of the Amida Buddha—are hidden Buddha images and are only displayed to the public on February 18th each year.
A hidden Buddha image is a Buddhist statue that is usually kept in a shrine and not seen by the general public, and traditionally is only displayed on specific days. At Iwasaki-ji Temple, a special display is held every year on February 18th, allowing visitors to view these precious, prefecturally designated cultural properties up close.
On days when the hidden Buddha statues are publicly displayed, many worshippers and Buddhist art enthusiasts visit from far and wide.
