60 years in the summer of 2008. On completion of the renovations, Ōkuninushi was returned to the inner shrine in a ceremony attended by over 8,000 people, held on May 11, 2013. Architecture The main structure of Izumo Oyashiro was built in the Taisha style, the oldest style of building shrines. An impressive sized gable-entrance structure is built for the main structure, which gave the name of The Great Shrine or The Grand Shrine. The main hall (honden) bears an enormous chigi (scissor-shaped finials at the front and back ends of the roof). A Japanese architecture book states, "In plan, the present Main Shrine resembles that of the Daijoe Shoden, built for the accession of each new Emperor. The main shrine at Izumo is thought, therefore, to preserve a floor plan characteristic of ancient domestic architecture" (Nishi & Hozumi, 1985, p. 41). From the view of architectures, the original height of the main structure of Izumo Taisha makes it difficult to study the historical building styles and methods. However, what is known is that from the construction of a building as big as the main structure, major problems were presented. Because of this, structural and stylistic changes occurred each time the main structure was rebuilt, which caused the outer form to be less reflective of the original construction of the main structure. Although the outside of the structure changed with each reconstruction, the floor plan remained virtually unchanged. The layout consists of nine support pillars arranged so that the inside is divided into four sections and causes the entrance to be off-centered. A significant characteristic that is common among most shrines is the symmetrical design, making the main structure of Izumo-taisha peculiar for its asymmetrical floor plan. The main structure was built more like a home rather than a shrine which suggests that between the people and kami there was a less formal relationship than at other shrines. Kagura-den Izumo-taisha's was first built in 1776 by the Senge family, Izumo Kokusō, or governor of Izumo, as a grand hall for performance of traditional rituals. It was rebuilt in 1981 to commemorate the centennial of the foundation of the Izumo Oyashiro-kyo order. Traditional prayer by Izumo Kokuso, wedding ceremonies of believers, and the performances of sacred dance to ancient Japanese music involve the Oracle with 240 mats. Also worshipped with prayer is a frame with four dyed Kanji characters, meaning "the
