Ame no Mihashira no Mikoto - Ame no Mihashira no Mikoto

...The Imperial Court dispatched messengers to hold the festival, and the Engishiki stipulated that it should be held on the 4th of both April and July. The Tatsuta Wind God Festival Prayer in the same book also states that Amenomihashira-no-Mikoto and Kuni-no-Mikoto were worshiped in the field of Tatsuta, and offerings were made to the god of Tatsuta, and prayers were made to protect the rice grown by the people of the country from bad winds and rough waters. The first appearance of this festival was in the April entry of the 4th year of Tenmu (675) in the Nihon Shoki, which states that officials were sent to worship the wind god in Tatsuta's Tatsuno and the oikigami in Hirose's Kawai, along with the Oimi Festival held at Hirose Shrine (now Kawai-cho, Kitakatsuragi-gun, Nara Prefecture). From then on, records of the festival being held every April and July until the end of the Nihon Shoki can be found.
