Construction on Iga Ueno Castle began in 1585 by the command of Takigawa Katsutoshi. However, the "honmaru", or innermost bailey, as well as the "tenshu", or donjon, upon which the modern reconstruction was based were built by Katsutoshi's successor, Tsutsui Sadatsugu. Sadatsugu was then succeeded by Tōdō Takatora. Takatora renovated the "honmaru", giving it high walls. This meant that the walls of the "honmaru" of Iga Ueno Castle were the tallest of any castle in Japan, a record that still holds. After the threat of rebellion passed, the castle was not seen to be as important as it once was. As a result, the "tenshu" was not re-built after it was destroyed by high winds in 1612. Because of its beautiful architecture, and floor plan, Iga Ueno Castle is also known as "Hakuho" or "White Phoenix Castle."
