Almost no historical documents from the Lower Shrine (which includes Harumiya) survived through the centuries. Nearly all records about Suwa Taisha come from the Upper Shrine across the lake.

Harumiya means 'Spring Shrine' because the deity traditionally resides here from February to July, then moves to nearby Akimiya (Autumn Shrine) for the rest of the year in a seasonal ritual unique to Suwa Taisha.
