The Aoi Matsuri (葵祭), or "Hollyhock Festival," is one of the three main annual festivals held in Kyoto, Japan, the other two being the Festival of the Ages (Jidai Matsuri) and the Gion Festival. It is a festival of the two Kamo shrines in the north of the city, Shimogamo Shrine and Kamigamo Shrine. The festival may also be referred to as the Kamo Festival. It is held on 15 May of each year.
The festival originated in the 7th century, most likely as an appeal to the gods after a storm destroyed the harvest. The emperor made offerings to the gods of the Shimogamo and Kamigamo Shrines, believed to be the deities responsible for the destruction. After this, the harvest was saved.
