Gozan no Okuribi (五山送り火), more commonly known as Daimonji (大文字), is a festival in Kyoto, Japan. It is the culmination of the Obon festival on August 16, in which five giant bonfires are lit on mountains surrounding Kyoto city. It signifies the moment when the spirits of ancestors, who are said to visit this world during O-Bon, are believed to be returning to the spirit world—thus the name Okuribi (送り火, roughly, "send-off fire").

​

The origins of the festival are believed to lie in the ancient roots of Obon with specific families having the hereditary duty of organising the logistics of the bonfires. The festival is held every year on August 16th.
