The taiko is a Japanese drum that comes in various sizes and is used to play a variety of musical genres. It has become particularly popular in recent years as the central instrument of percussion ensembles whose repertory is based on a variety of folk and festival music of the past. Such taiko music is played by large drum ensembles called kumi-daiko. Its origins are uncertain, but can be sketched out as far back as the 6th and 7th centuries, when a clay figure of a drummer indicates its existence. Chinese and Korean influences followed, but the instrument and its music remained uniquely Japanese. Taiko drums during this period were used during battle to intimidate the enemy and to communicate commands. Taiko continue to be used in the religious music of Buddhism and Shintoism. In the past players were holy men, who played only at special occasions and in small groups, but in time secular men (rarely women) also played the taiko in semi-religious festivals such as the bon dance.

Modern ensemble taiko is said to have been invented by Daihachi Oguchi in 1951. A jazz drummer, Oguchi incorporated his musical background into large ensembles, which he had also designed. His energetic style made his group popular throughout Japan, and made the Hokuriku region a center for taiko music. Musicians to arise from this wave of popularity included Sukeroku Daiko and his bandmate Seido Kobayashi. 1969 saw a group called Za Ondekoza founded by Tagayasu Den; Za Ondekoza gathered together young performers who innovated a new roots revival version of taiko, which was used as a way of life in communal lifestyles. During the 1970s, the Japanese government allocated funds to preserve Japanese culture, and many community taiko groups were formed. Later in the century, taiko groups spread across the world, especially to the United States. There is now a video game, called Taiko Drum Master, about taiko. A taiko ia also used to play video games.
