Hiroshima Castle (Carp Castle): What It Is

Hiroshima Castle (Hiroshima-jō) is one of Hiroshima’s landmark castles, located in the heart of Hiroshima City, Hiroshima Prefecture.

Construction began in Tenshō 17 (1589) by the Sengoku daimyō Terumoto Mōri (Mōri Terumoto), built on a delta at the mouth of the Ōta River. Known for its beautiful black exterior, the castle is also called “Carp Castle (Rijō)”.

The atomic bombing of 1945 destroyed the main keep and all buildings, but in 1958 (Shōwa 33) the keep was reconstructed in its exterior appearance. Today, the interior is open as a museum introducing Hiroshima’s history and culture.

With its moats and stone walls still remaining, Hiroshima Castle—selected as one of Japan’s Top 100 Castles—is loved by locals and visitors alike.

In this guide, we’ll cover Hiroshima Castle’s highlights, history, and practical tips for your visit.


Top Things to See at Hiroshima Castle

Because there may be periods when the keep interior is closed, checking opening information before your visit is recommended.
