Taiko drumming has been part of Japanese culture for centuries, played in religious festivals and ceremonies. It was also used in warfare to intimidate enemies. The Kodo troupe popularized taiko globally in the last 40 years through regular international tours. Based in Sado Island, Japan, Kodo performances feature traditional drums and other instruments along with dance and vocal performances lasting around two hours. The largest taiko drum, the odaiko, can weigh over 4 tons and be over 9 feet in diameter.
