諏訪神社
Historically, the Upper and the Lower Shrines have been two separate entities, each with its own set of shrines and religious ceremonies. The existence of two main sites, each one having a system parallel to but completely different from the other, complicates a study of the Suwa belief system as a whole. One circumstance that simplifies the matter somewhat, however, is that very little documentation for the Lower Shrine has been preserved; almost all extant historical and ritual documents regarding Suwa Shrine extant today are those of the Upper Shrine.
