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").
The origins of the festival are obscure, but it is believed to be ancient. Specific families have the hereditary duty of organising all the logistics of the bonfires, and they spend many hours annually providing volunteer labor to maintain this tradition.
Starting at 8 PM, the giant bonfires are lit, each with a distinctive shape. Three of the fires form giant Chinese characters, and two form familiar shapes. The characters, their locations, meanings, and the lighting times are:
Daimonji (大文字), Dai (big 大) is on Mt. Daimonji (大文字), which rises behind Ginkakuji Temple (The Silver Pavilion) in the eastern mountains of Kyoto.
Myo (妙) and Ho (法) are in Matsugasaki in northern Kyoto, on Mt. Mantoro and Mt. Daikokuten respectively. They are counted as one mountain. Myoho means “the supreme law” in Buddhism.
Funagata, (shape of a ship 船形) is on Mt. Myoken in Nishigamo in the northwest part of Kyoto.
Left-side Dai (左大文字) is on Mt. Ookita, which rises behind Kinkakuji Temple (The Golden Pavilion).
Toriigata (shape of a torii gate 鳥居形)” is on Mt. Mandara in Saga on the west side of Kyoto.
The most famous—and the first to be lit—is the character dai (大), on Kyoto's Daimonji-yama. The other four fires are lit at five to ten-minute intervals, and by 8:30, all the characters can be seen. Each bonfire lasts for 30 minutes.
The best place to view the festival is from the Nakagyo Ward, in the center of the city. Many hotels have Daimonji specials where, for a fee, you can see all five fires. Many people also like to go to the Kamo River, between Sanjo and Imadegawa Streets, for an excellent view of the initial fires.
