Kashima Shrine
According to local folklore, Sika deer from this area were considered sacred due to a visit from Takemikazuchi-no-mikoto, one of the four gods of Kasuga Shrine. He was said to have been invited from Kashima Shrine in present-day Ibaraki Prefecture, and appeared on Mount Mikasa (also known as Mount Wakakusa) riding a white deer. From that point, the deer were considered divine and sacred by both Kasuga Shrine and Kōfuku-ji. Killing one of these sacred deer was a capital offense punishable by death up until 1637, the last recorded date of a breach of that law.
