Views of the reconstructed keep (tenshu) at Okazaki Castle, Aichi Prefecture. The castle is a ferro-concrete, three-tiered, five-floor donjon and the interior has some interesting exhibits of roof tiles from the original castle including its shachi, samurai battle swords, armour, and reproductions of Edo Period fireworks - another industry in which Okazaki has a long history. There are also video displays, dioramas of previous battles and information on Okazaki's history as a castle town.
