Odaiko simply means “big, fat drum”, and with very good reason: The worlds largest odaiko is almost ten feet across the head!

Odaiko can refer to a large drum of any style, but usually is reserved for drums of the nagado style. The odaiko on this page are all of the nagado (long body) style, which is the typical barrel shaped taiko that most people are familiar with.
