paid for the construction of a new headquarters building within the castle grounds and a short distance from the main tower, so that the castle could be enjoyed by the citizens and visitors of Osaka. Hiroshima Castle served as Imperial General Headquarters during the First Sino-Japanese War (1894–1895) and later as the headquarters for the 5th Infantry Division; Kanazawa Castle served as HQ for the 9th Infantry Division. For this reason, and as a way to strike against the morale and culture of the Japanese people, many castles were intentionally bombed during World War II. The main towers of the castles at Nagoya, Okayama, Fukuyama, Wakayama, Ōgaki, among others, were all destroyed during air raids. Hiroshima Castle is notable for having been destroyed in the atomic bomb blast on August 6, 1945. It was also on the grounds of Hiroshima Castle that news of the atomic bombing was first transmitted to Tokyo. When the atomic bomb detonated, a team of volunteer high school girls had just taken their shift on a radio in a small fortified bunker in the main courtyard of Hiroshima Castle. The girls transmitted the message that the city had been destroyed, to the confused disbelief of the officers receiving the message in Tokyo. Shuri Castle (actually a Ryukyuan gusuku), on Okinawa Island was not only the headquarters for the 32nd Army and the defense of Okinawa, but also has the distinction of the being the last castle in Japan attacked by an invading force. In April 1945, Shuri Castle was the coordinating point for a line of outposts and defensive positions known as the "Shuri Line". US Soldiers and Marines encountered fierce resistance and hand-to-hand combat all along the Shuri Line. Starting on May 25, the castle was subjected to three days of intense naval bombardment from the USS Mississippi. On May 28, a company of US Marines took the castle, finding that the intensity of the destruction had prompted the headquarters contingent to abandon the castle and link up with scattered units and continue the defense of the island. On May 30, the US flag was raised over one of the parapets of the castle. Shuri Castle was re-built in 1992, and is now an UNESCO World Heritage Site. Over of the Shuri Castle were burnt down due to an electrical fault on 30 October 2019 at around 2.34 am. Reconstruction and conservation During the
