http://www.guillaumeerard.com/en/japan/events/tokyo-koenji-awaodori.html Each year in late August the Kōenji Awa Odori festival is held over three days. This is increasingly becoming a major tourist attraction for the area. It is the second largest Awa Dance Festival in Japan, with an average of 188 groups composed of 12,000 dancers, attracting 1.2 million visitors over the course of the weekend.[1] The festival has its origins in Tokushima and was adopted by Kōenji post-war. It involves a procession of groups performing traditional music and dance, and is enjoyed by a wide variety of people. The procession weaves its way through the streets on both sides of Kōenji Station, often with a dramatic conclusion at the "finish line". (excerpt from Wikipedia)
