Kozashi Castle in Aizuwakamatsu City is the ruins of a castle built during the turbulent period of the Warring States period. It is said that Uesugi Kagakatsu ordered Naoe Kanetsugu to build this castle, which is known as the site of fierce battles.
Construction of Kozashi Castle proceeded in a rush and was completed in only one year. The earthen mounds and stone walls still remain today, and its solid structure is considered to be the best of the technology of the time. However, the construction was interrupted by Tokugawa Ieyasu's attack on Aizu, and the castle became a battlefield.
Today, the ruins of Kozashi Castle are mostly reclaimed and turned into rice paddies, with only portions of the Honmaru and Ninomaru ruins remaining. However, the earthworks and stonewalls that remain remind visitors of the castle's appearance in those days and make them feel the weight of history. A large zelkova tree towering over the ruins of Ninomaru welcomes visitors to this historical site.
The ruins of Kozashi Castle, with its beautiful scenery of history and nature, are well known to many people. Especially in spring, the area is famous for its cherry blossoms, which attract many tourists. In recent years, the castle ruins have attracted more and more attention as a stage for events and the filming of period dramas.
The ruins of Kozashi Castle are a quiet and tranquil place surrounded by rich nature. It is a precious spot where visitors can enjoy nature while following in the footsteps of history. Why not visit when you visit Aizu Wakamatsu?
