Obon or just Bon is a Japanese Buddhist custom to honor the departed (deceased) spirits of one's ancestors. It has been celebrated in Japan for more than 500 years and traditionally includes a dance, known as Bon-Odori.

Bon Odori meaning simply Bon dance is a style of dancing performed during Obon. Originally a Nenbutsu folk dance to welcome the spirits of the dead, the style of celebration varies in many aspects from region to region. Each region has a local dance, as well as different music. The music can be songs specifically pertinent to the spiritual message of Obon, or local min'yo folk songs.

The way in which the dance is performed is also different in each region, though the typical Bon dance involves people lining up in a circle around a high wooden scaffold made especially for the festival called a 'yagura'. The yagura is usually also the bandstand for the musicians and singers of the Obon music. Some dances proceed clockwise, and some dances proceed counter-clockwise around the yagura. Some dances reverse during the dance, though most do not. At times, people face the yagura and move towards and away from it. Still some dances, such as the Kagoshima Ohara dance, and the Tokushima Awa Odori, simply proceed in a straight line through the streets of the town.

The dance of a region can depict the area's history and specialization. For example, the movements of the dance of the Tankō Bushi (the "coal mining song") of old Miike Mine in Kyūshū show the movements of miners, i.e. digging, cart pushing, lantern hanging, etc. All dancers perform the same dance sequence in unison.
