Hiroshima is the capital of Hiroshima Prefecture in Japan. As of June 1, 2019, the city had an estimated population of 2.089 million. The gross domestic product in Greater Hiroshima, Hiroshima Urban Employment Area, was US$61.3 billion as of 2010. Kazumi Matsui has been the city's mayor since April 2011.
Hiroshima was founded in 1589 as a castle town on the Ōta River delta. Following the Meiji Restoration in 1868, Hiroshima rapidly transformed into a major urban center and industrial hub. In 1889, Hiroshima officially gained city status. The city was a center of military activities during the imperial era, playing significant roles such as the First Sino-Japanese War, the Russo-Japanese War, and the two world wars.
Hiroshima is best remembered as the first city targeted by a nuclear weapon when the United States Army Air Forces dropped the atomic bomb "Little Boy" on the city at 8:15 a.m. on August 6, 1945. Most of the city was destroyed, and by the end of the year 90,000–166,000 had died as a result of the blast and its effects. The Hiroshima Peace Memorial serves as a memorial of the bombing.
