Hiroshima Castle (広島城), nicknamed 'Carp Castle' (鯉城, Rijō) for the carp that once swam in its moats, is a reconstructed five-story castle in central Hiroshima, originally built in 1589 by feudal lord Mori Terumoto. The castle served as the administrative and military center of Aki Province (modern Hiroshima) until the Meiji Restoration (1868), and during World War II, it housed the Imperial General Headquarters. The original castle was destroyed by the atomic bomb in 1945 — located 1km from the hypocenter, it was obliterated instantly, with only stone foundations remaining.

The current structure is a 1958 concrete reconstruction faithfully replicating the original's five-story exterior with white walls, dark wooden accents, and elegant curved rooflines. The interior houses a museum documenting Hiroshima's feudal history, samurai culture, and castle architecture, with exhibits on Mori clan governance, Edo-period city life, and wartime history. The top floor observation deck offers 360° views of Hiroshima City, Peace Memorial Park, and the Seto Inland Sea. The castle grounds feature original stone walls (surviving the atomic bomb), two reconstructed turrets, and Hiroshima Gokoku Shrine — a Shinto shrine honoring war dead. Cherry blossoms (late March–early April) transform the grounds into a hanami spot, with 370 cherry trees creating a pink canopy over moats and pathways.

Insider Guide

**Museum content:** Hiroshima Castle's museum focuses on Edo-period samurai culture and regional history rather than wartime events (that's Peace Memorial Museum's domain). Exhibits include samurai armor and swords, reproductions of castle interiors, dioramas of feudal Hiroshima, and explanations of castle construction techniques. English signage is present but limited; audio guides (¥300) are recommended for deeper understanding. The museum is educational but not world-class — its value lies in architectural appreciation and historical context rather than rare artifacts. **Castle vs. Peace Park:** Hiroshima Castle and Peace Memorial Park represent opposite poles of Hiroshima's identity — feudal military power versus peace advocacy. Visiting both provides balanced perspective. The castle was a military headquarters until the atomic bomb obliterated it, symbolizing the destruction of Japan's wartime regime. Its reconstruction represents post-war recovery and cultural preservation. Allocate 60 minutes for the castle, 2–3 hours for Peace Memorial Park and museum; combined, they form a comprehensive Hiroshima historical narrative. **Cherry blossom season:** Hiroshima Castle's moats and grounds host 370 cherry trees, blooming late March to early April (peak typically April 1–5, varies yearly). Evening illuminations during bloom (18:00–21:00) light the castle and cherry trees, creating photogenic nighttime scenes. Hanami (cherry blossom viewing) here is less crowded than famous Tokyo or Kyoto spots, offering a relaxed, local atmosphere. Bring a picnic blanket and konbini snacks for casual hanami beneath blossoms with the castle as a backdrop.
