Ōmiwa Shrine (大神神社, Ōmiwa-jinja), also known as Miwa Shrine (三輪神社, Miwa-jinja; alternately written as Miwa-myōjin (三輪明神)), is a Shinto shrine located in Sakurai, Nara Prefecture, Japan. The shrine is notable because it contains no sacred images or objects, since it is believed to serve Mount Miwa, the mountain on which it stands. For the same reason, it has a worship hall (拝殿, haiden), but no place for the deity to be housed (神殿, shinden). In this sense, it is a model of what the first Shinto shrines were like. Ōmiwa Shrine is one of the oldest extant Shinto shrines in Japan and the site has been sacred ground for some of the earliest religious practices in Japan. Because of this, it has sometimes been named as Japan's first shrine. Ōmiwa Shrine is a tutelary shrine of the Japanese sake brewers.

Ōmiwa Shrine in the context of Haiden (Shinto)
In Shinto shrine architecture, the haiden (拝殿) is the hall of worship or oratory. It is generally placed in front of the shrine's main sanctuary (honden) and often built on a larger scale than the latter. The haiden is often connected to the honden by a heiden, or hall of offerings. While the honden is the place for the enshrined kami and off-limits to the general public, the haiden provides a space for ceremonies and for worshiping the kami. In some cases, for example at Nara's Ōmiwa Shrine, the honden can be missing and be replaced by a patch of sacred ground. In that case, the haiden is the most important building of the complex.
