Hiroshima Castle
A flatland fortress on the Ota River delta, rebuilt with quiet dignity
Hiroshima Castle — known locally as Rijo — rises from the broad delta of the Ota River, its white-walled keep reflected in a moat that still invites leisurely boat cruises. Built by Mori Terumoto, the castle grounds today centre on the main and second baileys, where the reconstructed Ninomaru buildings open free of charge. Inside, special exhibitions trace the castle's layered history, a museum shop offers thoughtful keepsakes, and performances by the Aki Hiroshima samurai troupe bring the grounds to life with surprising theatricality.
When to go
The castle is open daily from 9 am to 6 pm, making early-morning visits particularly rewarding — the moat catches the light before the day's foot traffic builds. Spring and autumn both flatter the grounds, though any season rewards a measured, unhurried pace.
