Aizuwakamatsu Castle

Aizuwakamatsu Castle, historically known as Tsuruga Castle, is a prominent Japanese castle located in the center of Aizuwakamatsu city within Fukushima Prefecture. Originally established in 1384 by Ashina Naomori as Kurokawa Castle, the site served as a strategic stronghold in the Aizu basin during the Nanboku-cho period. The structure underwent a major transformation in 1592 under the rule of Gamō Ujisato, who rebuilt it into a modern hirayamashiro, or hilltop castle. Ujisato famously constructed an unprecedented seven-story tenshu keep in 1593, renaming the fortress Tsuruga Castle to reflect its new status and architectural grandeur.

The castle holds significant historical importance due to its association with several powerful warlords, including Date Masamune, Uesugi Kagekatsu, and Katō Yoshiaki, who each influenced its development and defensive layout. It played a pivotal role during the turbulent Sengoku period and later became a symbol of resistance during the Boshin War in the Meiji Restoration era. Following centuries of service as a military and administrative center, the original structures were eventually dismantled, with the main keep demolished in the late 19th century after the castle ceased official use in 1889.

Today, the site is recognized as a National Historic Site of Japan. While the original wooden buildings no longer stand, the iconic tenshu was reconstructed in 1965 using concrete to preserve the visual heritage of the landmark. The castle grounds now serve as a public park and museum, allowing visitors to explore the rich history of the Aizu region. Despite the modern materials used in reconstruction, the castle remains a vital cultural symbol, representing the resilience and evolving legacy of northern Japan's feudal past.
