The Thunder Big Drum is a Hagyuu School training device whose origins lye in a ritual practice used to bring rain.


When the drum sounds like thunder under a clear sky, the dragon of heaven will be surprised and call the rain”.


The Thunder Big Drum is used to determine mastery of the Hagyuu School by beating the drum using the shockwave of its ultimate technique Kaze Atemi. One is considered a master when they are able to strike the drum twice simultaneously.
