Hiroshima Prefecture is a prefecture on the island of Honshu in the Chūgoku region of Japan, with its capital at Hiroshima. The prefecture spans coastal and inland areas including the Seto Inland Sea islands and borders Yamaguchi Prefecture, Shimane Prefecture, and Okayama Prefecture, with transport links to Kobe, Osaka, and Tokyo via rail and air. Known for industrial centers, maritime landscapes, and sites of modern history, the prefecture is a nexus for manufacturing, cultural heritage, and postwar commemoration.
Hiroshima lies along the Seto Inland Sea coast and encompasses island chains such as the Miyajima archipelago and the Geiyo Islands, bordering the Chūgoku Mountains and river systems including the Ōta River, Yasaka River, and Gōno River. The prefecture contains varied terrain from the urban plain of Hiroshima (city) to mountainous districts near Onomichi, Fukuyama, and Shōbara, and features protected areas associated with Setonaikai National Park and coastal ecosystems linked to Inland Sea (Seto) fisheries. Transportation corridors include the Sanyo Shinkansen, Sanyō Main Line, and the Sanyō Expressway, while ports such as Hiroshima Port and Kure Port connect to shipping routes toward Shikoku and Kyushu.
The area was part of feudal provinces like Aki Province and Bingo Province during the era of Kamakura shogunate and Muromachi period power struggles involving clans such as the Mōri clan and figures including Mōri Motonari and Uchida Ieyoshi. In the Sengoku and Azuchi–Momoyama periods, sites like Fukuyama Castle and Onomichi were strategic in campaigns by Toyotomi Hideyoshi and Tokugawa Ieyasu, shaping regional domain divisions under the Edo period han system. During the Meiji Restoration and Meiji period reforms, the modern prefectural system emerged alongside developments tied to Sanyō Railway expansion and industrialization led by firms with links to the Mitsubishi and Sumitomo zaibatsu networks. In the 20th century, naval bases at Kure and wartime industries made the region central to the Pacific War logistics; the atomic bombing of Hiroshima (city) on 6 August 1945, involving the B-29 Superfortress Enola Gay and the Trinity test precedents, transformed global discourse through institutions such as the International Atomic Energy Agency and postwar movements including Mayors for Peace and Peace Studies initiatives at universities like Hiroshima University.
The prefecture's population centers include Hiroshima (city), Fukuyama (city), Kure (city), and Miyoshi (city), with demographic trends reflecting Japan-wide aging patterns tracked by agencies such as the Statistics Bureau of Japan and policies influenced by the Basic Act on Countermeasures for Aging Society.

Public health systems interact with national programs overseen by the Ministry of Health, Labour and Welfare, and civil society organizations collaborate with groups such as Red Cross Society of Japan and peace NGOs formed after the Hiroshima Peace Memorial Museum initiatives.
Industrial hubs around Hiroshima (city), Fukuyama (city), and Kure (city) host manufacturers linked to global firms including Mazda Motor Corporation, shipyards servicing clients like Mitsui Engineering & Shipbuilding, and steelworks historically affiliated with Sumitomo supply chains. The regional economy integrates agriculture from plains producing rice and citrus varieties marketed through cooperatives such as JA Group and fisheries harvesting oysters in the Seto Inland Sea supply chain sold to markets in Tokyo and Osaka. Logistics rely on facilities connected to Hiroshima Airport, freight terminals at Hiroshima Bay, and export routes coordinated with ports in Kobe and Nagoya. Innovation clusters involve research partnerships among Hiroshima University, corporate R&D centers, and government programs funded by the Ministry of Economy, Trade and Industry to support SMEs and technology transfer.
Cultural heritage sites include Itsukushima Shrine on Miyajima, Hiroshima Peace Memorial (Genbaku Dome), Shukkeien Garden, and castles such as Hiroshima Castle and Fukuyama Castle, attracting visitors via routes promoted by the Japan National Tourism Organization and local tourism bureaus.
