As of 22 March 2026, the castle is closed due to structural deterioration, although the grounds are open are free to roam around. The original Carp Castle (Rijō) was built in the 1590s by Hideyoshi's warlord Terumoto Mōri, predating the city itself. It was destroyed by the atomic bomb, by which time it was serving as a military headquarters, and reconstructed in using modern materials in 1958. Some of the original stone foundations can still be seen. Today, the castle grounds are a nice place for a walk, and definitely Hiroshima's favorite place for hanami (cherry blossom parties), with more than 350 sakura trees. The five-story castle museum is an attractive reconstruction of the 16th century donjon, with interesting relics and armor to see (and try on), as well as some informative displays about the history of the castle and the city. The view from the top is worth the entrance fee all by itself. Photography is allowed for self-use only. Gift shop sells various Warring States period-related goods, while the stamp-collecting area for Japanese Top 100 Castles is outside the castle. No elevators are available - visitors will be walking the five stories by stairs.
Hiroshima Castle , sometimes called Carp Castle , is a castle in Hiroshima, Japan that was the residence of the daimyō of the Hiroshima Domain. The castle was originally constructed in the 1590s, but much of it was dismantled in the Meiji era, and what remained was largely destroyed by the atomic bombing on August 6, 1945. The main keep was rebuilt in 1958, a replica of the original that now serves as a museum of Hiroshima's history before the Second World War, and other castle buildings have been reconstructed since.

護国神社 Gokoku-jinja
Located on the castle grounds, this concrete shrine has great significance to locals, having been rebuilt after the atomic blast and now the center for most annual Shinto traditions in the city. But other than a historical marker, there's not much to see for travelers, other than festivals (especially New Year's Eve).
中央公園
A big, sprawling green space in the middle of the city. Broadly defined, the park grounds include many of the attractions below, including the castle and the Carp's old baseball stadium (scheduled for demolition). But Chuo Park is worthy of note in its own right, with nice, long walking paths and athletic fields — there are quite a lot of open-invitation soccer, football, and ultimate frisbee games that are regularly held here, so don't be shy about showing up with athletic shoes and seeing if anyone needs an extra.
ひろしま美術館
Established by the Hiroshima Bank in 1978. The permanent collection covers European art from late Romanticism to early Picasso, including a couple of Japanese painters who painted in Western styles. There's at least one painting by every famous artist of the period, but no major works by any of them.
広島市こども文化科学館
Great fun for kids, with hand-on science exhibits and a planetarium on the top floor. There's also a library with a few shelves of English language books.
広島県立美術館
Has a good permanent collection of modern European art, including major works by Dali and Magritte, and a few modern Japanese artists as well. Special exhibitions are of a generally high quality, ranging from Persian carpets to The Legend of Ultraman. It's located in front of Shukkeien.
There are carp ponds, tea houses, and flowering trees in the tranquil urban gardens that were created in the 16th century.
