Hiroshima Castle is a historic flatland castle (hirajiro) constructed during the transition from the Azuchi-Momoyama to the Edo period. It holds the nickname 'Rijo' (Carp Castle), a name that is also the origin of the Hiroshima Toyo Carp baseball team's name. Although the original structures, including the main keep, were destroyed by the atomic bombing in 1945, the castle tower was rebuilt in 1958. Today, it serves as a vital museum dedicated to the history, folklore, and natural history of the Hiroshima region.
The history of Hiroshima Castle began in 1589 when Mori Motonari built the fortress on the delta of the Ota River. It was originally a massive fortification and developed as the center of the Hiroshima Domain during the Edo period. In the mid-Edo period, the castle underwent significant renovations by Fukushima Masanori, expanding into a vast complex with inner, middle, and outer moats. In more recent history, the main enclosure served as a military headquarters during the Sino-Japanese War, highlighting its role as a central military hub. While much of the original architecture was lost due to the atomic bomb, the current keep and surrounding buildings serve as a reconstructed testament to its historical grandeur.

The interior of the castle tower (tenshukaku) features permanent exhibits from the 1st to the 3rd floors, showcasing the formation of Hiroshima Castle, the lifestyle of the castle town, and impressive collections of samurai armor and swords. The 4th floor is dedicated to special exhibitions, while the 5th floor serves as an observation deck, offering breathtaking views of Hiroshima City. Visitors can also admire the beautiful stone walls and moats that surround the castle, providing a clear look at traditional Japanese castle architecture. The Ninomaru area often hosts historical displays and seasonal events.
The operating hours for the castle tower vary depending on the season. From March to November, it is open from 9:00 AM to 6:00 PM. From December to February, it is open from 9:00 AM to 5:00 PM. Please note that the last entry is 30 minutes before closing. Additionally, special evening events such as the 'KAGURA Night Market' are sometimes held, allowing visitors to experience the historical atmosphere under the night sky.

Beyond viewing the historical exhibits inside the tower, visitors can enjoy special exhibitions themed around Hiroshima's unique culture. The surrounding area occasionally hosts performances of 'Kagura,' a traditional Japanese dance and music, providing a direct connection to local heritage. A stroll through the castle grounds allows you to visually understand the structure of the former castle town and the reconstructed architectural styles.
Several historical sites are located near Hiroshima Castle. A must-visit is Shukkeien Garden, a beautiful traditional Japanese garden created by the first lord of the Hiroshima Domain, Asano Nagashige. Additionally, 'Okonomimura'—a hub for Hiroshima's soul food, Hiroshima-style Okonomiyaki—is nearby, allowing you to pair your historical exploration with a taste of local culinary culture.
