The tenth month of the lunar calendar is called Kannazuki. This was a common name in the days when people lived according to the waxing and waning of the moon. According to folklore, all of the gods throughout Japan gathered in the Izumo region of Japan and held a meeting. As a result, other regions were emptied of gods. This period was called 'Kannazuki,' or the month of no gods. Conversely, in the region of Izumo, this time is called 'Kamiarizuki,' or the month when all gods are present.

On the evening of the tenth day of the tenth month of the old Japanese calendar, Shinto rituals and the Kamimukae festival are held to welcome all of the gods of the country in Inasanohama, which is not far from Izumo Taisha. From the eleventh day to the seventeenth day a meeting called Kamuhakari is held. In it the fate of humanity, marriages between men and women and other matters are decided. During this time, the festival of Kamiari is held at Kaminomiya, which is near to Inasanohama. On the final day, the seventeenth, the farewell festival known as Karasade is held.
