The castle was the final stronghold of the Aizu clan during the Boshin War, surviving a month-long siege against Imperial forces.
The castle keep was rebuilt using a rare red-tile aesthetic to reflect its appearance during the late Edo period.
The Rinkaku Tea House was saved from destruction in 1874 by a local government official who moved it to a private residence before its eventual return to the park.
The stone walls surrounding the moat were constructed using a 'boshin' technique that allows them to withstand seismic activity.
The park contains the site of the former Aizu Domain school, Nisshinkan, which educated young samurai in literature and martial arts.
Tsuruga Castle City Park surrounds the reconstructed 1960s concrete keep of Tsuruga Castle, originally built in 1384 and famously destroyed during the 1868 Boshin War. The park grounds feature stone walls, deep water-filled moats, and extensive cherry blossom groves containing over 1,000 trees. The site houses the Rinkaku Tea House, a relocated structure surviving the Meiji-era demolition. The castle keep serves as a local museum displaying samurai armor, weapons, and historical artifacts related to the Aizu domain. Visitors can climb to the top level for a panoramic view of the Aizuwakamatsu basin. The park is designated as a significant historical site by the Japanese government. The current keep utilizes red roof tiles, a feature unique to this specific reconstruction in Japan.
The view of the castle reflected in the northern moat, particularly when the cherry blossoms are in full bloom.
Purchase a combined entry ticket if you intend to visit both the main keep and the Rinkaku Tea House.
Wear comfortable walking shoes, as the perimeter of the moats and the castle grounds involve significant walking on gravel paths.
Visit during early spring to view the cherry blossoms, though be prepared for crowds during peak bloom.
Avoid visiting on public holidays if you prefer solitude, as the park grounds become heavily congested.
The facility is open daily year-round, though individual interior sections may occasionally close for maintenance.
Maintain silence inside the tea house; follow path markers to protect historical stonework; do not touch artifacts in the museum.
