Izumo-taisha's Kaguraden (神楽殿 Kagura hall) 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
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 Chinese characters, meaning “the Oracle Filled with Aureole,” by Prince Arisugawa above the altar.
The Kagura-den features the largest shimenawa (sacred straw rope) in Japan; it is 13.5 meters long and weighs around 5 tons. The rope is one of the most easily recognized and distinctive features of Izumo-taisha.
