Treasure Hall of Izumo Taisha (神祜殿)

The hall was completed in 1981 to a design by Kiyonori Kikutake (1928-2011), a key figure in the Metabolist movement of the 1960s. It serves as the shrine's treasure hall, where the shrine shows the public the precious objects in its keeping.

Its name means "the help of the gods" or "receiving good fortune from the gods".

A renovation carried out to commemorate the Great Relocation of the Heisei era renewed the exhibition space, and the hall reopened on 23 November 2017.

It was built facing the shrine's administrative building, completed in 1963 to Kikutake's design and no longer standing.

On the ground floor, the exhibition traces the history of the shrine: its origins, its sixty-year rebuilding cycle and its annual rituals. The remains of the central pillar (shin no mihashira) of an earlier main sanctuary occupy the centre. They came to light in the spring of 2000 in front of the Yatsuashi Gate ("eight-legged gate"), during a survey carried out before the basement of the worship hall was enlarged. A full-size section of roof shows how layers of cypress bark are stacked to make the roof of the main sanctuary.

Upstairs are a curved jade bead (magatama) and a bronze dagger-axe (dōka) of the Yayoi period, unearthed in the seventeenth century in the grounds of a shrine 200 m to the east, Inochinushi no Yashiro. The jade comes from Niigata Prefecture, the dagger-axe from northern Kyūshū. There is also a nineteenth-century two-string zither, the yakumo-goto: an ordinary koto has thirteen strings, and its maker said the god Ōkuninushi no Kami had revealed the design to him in a dream. Replicas of the multicoloured clouds painted on the ceiling of the main sanctuary complete the display.
