Izumo Grand Shrine

Izumo Grand Shrine stands in Izumo City, Shimane Prefecture, with Okuninushi-no-Okami as its principal enshrined kami. The hereditary priestly line of the ancient provincial governors (kuni-no-miyatsuko) of Izumo has officiated at the shrine since antiquity. The main hall exemplifies the taisha architectural style and was designated a national treasure in 1952.

The shrine precincts occupy the western plain of Izumo, sheltered by Mount Yakumo. According to tradition, ancient structures here far exceeded the height of the present main hall. A Heian-period saying, "Izumo exceeds Tōdai-ji exceeds Kyoto," ranked the shrine's building first among three great structures. In 2000, archaeological excavation within the shrine precincts uncovered timber remains of the central pillar from a Kamakura-period reconstruction—a composite column of three cryptomeria logs bound together, approximately three metres in diameter—confirming the tall-building tradition through material evidence.

The *Kojiki* records of the Land Cession myth establishes the shrine's mythic origin: Okuninushi-no-Okami ceded Ashihara-no-Nakatsukuni to the heavenly realm in exchange for the construction of a magnificent sanctuary. His sons Kotoshironushi-no-Kami and Takeminakata-no-Kami played crucial roles in this cession and remain key points in Izumo mythology.

While its founding date is unknown, the shrine appears in both the *Kojiki* and *Nihon Shoki* under the name Ame-no-Hisumi-no-Miya. The *Engishiki* (*Procedures of the Engi Era*, 927 CE) lists it as Kizuki Grand Shrine, a major shrine of the register. Following the Shinto-Buddhist separation (*shinbutsu-bunri*) of the Meiji period, it was renamed Izumo Grand Shrine in 1871. The main hall undergoes renewal and relocation approximately every sixty years; the most recent ceremony was the Heisei Great Relocation in 2013.

The Kami-Ari Matsuri (Festival of the Kami's Presence), held in the tenth month of the lunar calendar (around late November), is the shrine's defining festival. Tradition holds that the eight million kami gather in Izumo during this period for sacred council. The spring grand festival in May and the Cool Hall Rite in June are among the year-round observances.
