Hiroshima Castle

Hiroshima Castle, also known as “Carp Castle” (Rijō), is a historic Japanese castle located in the heart of Hiroshima City. Originally built in the 16th century, the castle was the center of power for local feudal lords and played a significant role in Japan’s feudal era. Surrounded by a scenic moat and wooded grounds, Hiroshima Castle today stands as a symbol of Hiroshima’s resilience and cultural heritage.

Although the original structure was destroyed by the atomic bomb in 1945, it was reconstructed in 1958 as a historical museum dedicated to Hiroshima’s samurai history, castle culture, and architectural legacy. It’s a must-visit for those interested in Japanese history, architecture, and serene park landscapes.

Why is Hiroshima Castle Famous?

Hiroshima Castle is famous for its historical and cultural significance as the seat of power for the feudal lord (daimyō) Mōri Terumoto, one of Toyotomi Hideyoshi’s top generals. Its original construction marked Hiroshima's transformation from a small fishing village to a political and economic hub in western Japan.

The castle is also a symbol of Hiroshima’s post-war recovery. After being destroyed by the atomic bombing in 1945, it was rebuilt and now serves as a museum preserving the story of Hiroshima’s samurai past, castle architecture, and military history.

Entry and Visit Details

The castle grounds are open to the public and free to explore. If you want to enter the reconstructed main keep (castle tower), which now functions as a museum, there is a small entrance fee:

• Adults: ¥370
• High school students and younger: ¥180
• Groups and special exhibitions: May have different pricing

Tickets can be purchased on-site. The museum features informative exhibits in both Japanese and English, covering topics such as the feudal history of Hiroshima, samurai armor and weapons, and historical maps.

History and Architecture

Hiroshima Castle was originally constructed in 1589 by Mōri Terumoto, who chose the location for its strategic value. Built in the typical Japanese style of the Azuchi-Momoyama period, the castle featured five stories, stone foundations, and wooden structures with black and white plaster walls.

After the Mōri clan was moved to another province, the castle passed into the hands of successive lords under the Tokugawa Shogunate. It remained a seat of regional government until the Meiji Restoration. Tragically, the castle was destroyed by the atomic bomb on August 6, 1945. Only the stone foundations and a few structures survived. The current reconstruction, completed in 1958, restored the castle’s exterior while modernizing the interior to serve as a museum.
