Guide
Tsuruga-jo Castle is a historic fortress located in Ote-machi, Aizu Wakamatsu City, Fukushima Prefecture. Often referred to as Aizu Wakamatsu Castle, it is affectionately known by locals as "Tsuruga-jo." The structure is a flatland-mountain castle (hirayama-jiro) consisting of the Honmaru (inner circle) surrounded by the Nishidemaru, Kitademaru, Ninomaru, and Sannomaru circles. The castle is a designated National Historic Site, and the main keep has been reconstructed with a reinforced concrete exterior to preserve its original appearance. Today, the interior of the keep serves as the Wakamatsu Castle Castle Museum, housing various local historical artifacts.
The origins of the castle date back to 1384, when it was established as a residence by Ashina Naomori, the 7th head of the Ashina clan. It was originally known as Kurokawa Castle (or Odaki Castle). Throughout the Sengoku period, the Ashina clan used this site as a stronghold. Later, after the rule of Date Masamune, it developed into the administrative center of the Aizu Domain. The castle has a deep connection to the Tokugawa Shogunate through the Aizu Matsudaira clan and was the site of intense battles during the Boshin War at the end of the Edo period. Today, the area is maintained as "Tsuruga-jo Park," preserving its historical legacy.
The most striking feature of Tsuruga-jo is its beautiful keep adorned with red tiles. The Honmaru area includes the main keep along with several structures such as the Iihimi-yagura (rice storehouse tower), Tsukimi-yagura (moon-viewing tower), and Chatsubo-yagura, as well as various gates like the Iron Gate and Back Gate. Visitors can observe the complex defensive structures by exploring the different circles (Ninomaru and Sannomaru) and their respective gates and towers. The interior of the keep functions as a museum, offering deep insights into regional history. The castle is also surrounded by several moats, such as the Otemae Nishi-hori and Minamacho-dori, which are essential to understanding the castle's defensive architecture.
Tsuruga-jo Park is recognized as one of "Japan's 100 Best Cherry Blossom Spots," making it a premier destination in the spring when the cherry blossoms are in full bloom. The castle offers different beautiful expressions throughout the four seasons. The castle and museum are open daily from 8:30 AM to 5:00 PM. Visiting during the bright daylight hours is recommended to clearly observe the intricate details of the keep and the surrounding moat structures. Spring and autumn are particularly recommended for experiencing the most dramatic seasonal landscapes.
