Himuro jinja (氷室神社) is a Shinto shrine in Nara, located directly across the street from the Nara National Museum.
Established in the 8th century, around the time the capital was moved to Nara, the central ritual at this shrine centered around encasing fish in blocks of ice, and offering them to the gods.
The main worship hall (haiden) is two ma wide, and one ma deep.
During the Edo period, the shrine was one of a number of sites employed by the Imperial Court and Tokugawa shogunate as a site for important government rituals. It was also a central hub of performers, of bugaku in particular (Japanese court dance). In earlier periods, Himuro jinja was a major gagaku (Japanese classical music) site as well. ®wiki.samurai-archives.com
