The festival of Obon lasts for three days; however its starting date varies within different regions of Japan. "Shichigatsu Bon" (Bon in July) is based on the solar calendar and is celebrated around 15 July in areas such as Tokyo, Yokohama and the Tohoku region. "Hachigatsu Bon" (Bon in August) is based on the solar calendar, is celebrated around the 15th of August and is the most commonly celebrated time. Bon Odori (盆踊り, meaning simply Bon dance is an event held during Obon. It is celebrated as a reminder of the gratitude one should feel toward one's ancestors.
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.
