Namura Shrine in Ayado in Ryuo Town, Shiga Prefecture, is a historic shrine and a treasure trove of cultural properties since most of the structures of the shrine are nationally designated as either a National Treasure (NT) or an Important Cultural Property (ICP). The origin of the shrine is not clear, but, as many Kofun (ancient Imperial tombs) have been discovered in the area, it is considered that this shrine was originally founded to enshrine the spirits of ancestors.

The Romon gate (ICP) has the impressively huge thatched roof. The wooden statue of Fudo Myoo (ICP) is enshrined in the Fudo Hall in the precinct, which is the reminder of Shinbutsu Shugo (the fusion of Shinto and Buddhism) practiced until the end of the Edo period (1868).

The main hall, Nishi-Honden (NT), was constructed in 969 to enshrine the deity Kunisazuchi no Mikoto, who had resided in Mt. Kongo in Yoshino in Yamato province (present-day Nara Prefecture). The old shrine located on the opposite side of the road is the east shrine, Higashi Honden (ICP), which enshrines Okuninushi no Mikoto and Susanoo no Mikoto.

Namura Shrine is the head shrine of all the branch shrines in 33 adjacent villages; hereby the Grand Autumn Festival is held once every 33 years.
