Japan:Aizu-Wakamatsu Castle

Aizu-Wakamatsu Castle, also known as Tsuruga Castle is a concrete replica of a traditional Japanese castle in northern Japan, at the center of the city of Aizuwakamatsu, in Fukushima Prefecture.
The castle was constructed by Ashina Naomori in 1384, and was originally named Kurokawa Castle. It was the military and administrative center of the Aizu region until 1868.
Date Masamune, the greatest warlord of the Tohoku area, had struggled against the Ashina clan for years, and finally captured the castle in 1589 at the Siege of Kurokawa Castle. But soon he submitted to Toyotomi Hideyoshi and gave it up in 1590.
