Yagura

Yagura (櫓, 矢倉?) is the Japanese word for: "tower", "turret", "keep", "scaffold". The word is most often seen in reference to structures within Japanese castle compounds, but can be used in a variety of other situations as well. The bandstand tower erected for Bon Festival is often called a yagura, as are similar structures used in other festivals. Yagura-daiko, that is, taiko drumming from atop a yagura is a traditional part of professional sumo competitions.
