Overview

Itsukushima Shrine is the main head shrine for all shrines dedicated to its name, located on Miyajima Island in Hiroshima Prefecture. It is renowned for its unique architectural style, which features a striking placement over the sea and incorporates design elements from the Heian Period (794–1185). In 1996, it was also designated a World Heritage Site. The National Treasure group—the Main Hall, Offering Hall, and Worship Hall—forms the core of the complex. These structures are considered the ultimate expression of architectural beauty, harmonizing perfectly with the surrounding ocean environment.

Historical Background

The founding of Itsukushima Shrine is traditionally attributed to Saekino Kuramoto, a local influential figure, in 593 CE (the first year of Emperor Suiko). During the late Heian Period, Taira no Kiyomori became a deep devotee and oversaw the construction of magnificent halls around 1168. This established the foundation for the large shrine complex seen today. The current Main Hall, Offering Hall, and Worship Hall were reconstructed in 1571 (the second year of Genki), with significant aid from Mōri Motonari during the late Muromachi Period. These buildings are valuable remnants that faithfully follow the Heian style established by Taira no Kiyomori while integrating superior architectural techniques developed during the Muromachi Period.

Features and Appeal

Although the Main Hall, Offering Hall, and Worship Hall are three separate structures, they create a unified and elegant composition by connecting their roofs.

Architectural Structure: The Main Hall utilizes ryōnagare-zukuri (a large and specialized form) which flows along both its front and back sides. The complex consists of the “Main Hall” (dedicated to the Three Goddesses of Munakata), the “Offering Hall” (where votive offerings are placed), and the “Worship Hall” (where worshippers pay respects). All three buildings share roofs finished with elegant hiwada-buki (cedar bark roofing).
Advanced Engineering: The construction demonstrates incredible ingenuity, especially given its challenging location over a tidal sea. Techniques include methods to protect pillars from corrosion and the inclusion of meaki, or gaps in the floorboards, designed to relieve pressure from high tides. These features showcase the advanced knowledge and technology of the era.
Aesthetics and Scenery: The contrast between the green backdrop of Mount Misen, the vibrant vermillion color of the shrine buildings, and the blue of the Seto Inland Sea creates overwhelming beauty. Especially at high tide, when the structures appear to float on the water, they create a magical landscape reminiscent of paradise, where nature and architecture become one.
Historical Significance: The site has been protected by powerful figures across history, including the Taira clan, Ashikaga clan, Mōri clan, Toyotomi clan, and Tokugawa clan. Though reconstructed during the Muromachi Period, it remains a unique monument in Japanese architectural history, conveying the elegance of the Heian era to the present day.
