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 O-Bon festival on August 16, in which five giant bonfires are lit on mountains surrounding the city. It signifies the moment when the spirits of deceased family members, 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").
