Hiroshima Castle Yagura-mon
The most common type of gate used for the Japanese castles is the Yagura-mon (from yagura "turret" and mon "gate") photographed here at the Hiroshima castle. As the name suggests, the gate has a yagura tower built on top, which improves the gate's resistance and offers space for defending troops.
