Content:  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

Title: Bombing of Yawata
Content:  The Japanese city of Yahata (which was incorporated into the larger city of Kitakyushu in 1963) was subjected to three major air raids during World War II, part of the U.S. strategic bombing campaign. The first raid took place on the night of 15/16 June 1944. This was the first attack on the Japanese home islands by United States Army Air Forces bombers since the Doolittle Raid of 1942. The city was next attacked during the day and night of 20 August 1944. These two attacks caused little damage to the city's industrial facilities. The third raid was conducted on 8 August 1945 and resulted in 21 percent of Yahata's urban area being destroyed. The third raid may have spared nearby Kokura from destruction, as Kokura was to be the primary target for the second atomic bomb the following day, but smoke from the fires in Yahata combined with cloud cover decreased visibility to the point that the secondary target of Nagasaki was bombed instead.
Title: Hyōgo-ku, Kobe
Content:  The concentration of military and industrial manufacturing facilities including Kobe Steel, Kawanishi Aircraft Company Kawasaki Aircraft Industries and the Kawasaki and Mitsubishi Shipyards made the city of Kobe a primary target of bombing by the United States during World War II. It suffered the highest fatality rate of the five major Japanese cities (the others being Tokyo, Yokohama, Nagoya and Osaka). The first attack upon Kobe was by one B-25 bomber as a part of the Dolittle Raid on 18 April 1942. With Japan's success in expanding its territory through south-east Asia at the time, an attack by foreign aircraft was not expected at the time and it was reported that some residents even waved flags at the plane as it flew overhead, thinking it was a Japanese aircraft.

Title: Bombing of Sendai during World War II
Content:  The city of Sendai was the largest population and commercial center of the Tohoku region of northern Honshu island, but lacked specific targets of strategic military significance. The Tōhoku Main Line railway connecting Tokyo with Aomori also ran through the city. The industrial city of Kamaishi was bombed on July 14, 1945, which was also the first air raid experienced in Miyagi Prefecture during the war. The first experience of Sendai with bombing was on March 10, 1945, when three B-29 Superfortress bombers from the Tokyo Air Raid dropped their bomb load on Mount Zaō for unknown reasons, killing 34 civilians, and an additional two B-29 bombers attacked Sendai Airport causing minor damage. On May 25, 1945, a photo-reconnaissance B-29 overflew Sendai at an altitude of 8000 feet, compiling a detailed map of the downtown area of the city. On July 10, 1945, another B-29 made an over flight of Sendai, this time dropping propaganda leaflets warning the residents of the city of its imminent destruction.

These attacks were followed by similar ones against Kobe, Osaka, and Nagoya, as well as other sectors of Tokyo, where over 9,373 tons of incendiary bombs were dropped on civilian and military targets. By the time of the dropping of the atomic bombs on Hiroshima and Nagasaki, light and medium bombers were being directed to bomb targets of convenience, as most urban areas had already been destroyed. In the 9-month long bombing campaign, over 300,000 Japanese civilians died and 400,000 were wounded.
Title: Japan during World War II
Content:   After securing airfields in Saipan and Guam in the summer of 1944, the United States Army Air Forces undertook an intense strategic bombing campaign, using incendiary bombs, burning Japanese cities in an effort to pulverize Japan's industry and shatter its morale. The Operation Meetinghouse raid on Tokyo on the night of March 9–10, 1945, led to the deaths of approximately 100,000 civilians. Approximately 350,000–500,000 civilians died in 66 other Japanese cities as a result of the incendiary bombing campaign on Japan. Concurrent to these attacks, Japan's vital coastal shipping operations were severely hampered with extensive aerial mining by the U.S.'s Operation Starvation. Regardless, these efforts did not succeed in persuading the Japanese military to surrender. In mid-August 1945, the United States dropped nuclear weapons on the Japanese cities of Hiroshima and Nagasaki. These atomic bombings were the first and only such weapons used against another nation in warfare. These two bombs killed approximately 120,000 to 140,000 people in a matter of minutes, and as many as a result of nuclear radiation in the following weeks, months and years. The bombs killed as many as 140,000 people in Hiroshima and 80,000 in Nagasaki by the end of 1945.

On 28 June Moji, Nobeoka, Okayama and Sasebo were attacked. Kumamoto, Kure, Shimonoseki and Ube were bombed on 1 July. Two nights later, Himeji, Kōchi, Takamatsu and Tokushima were attacked. On 6 July, attacks were conducted against Akashi, Chiba, Kōfu and Shimizu. Gifu, Sakai, Sendai and Wakayama were struck on 9 July. Three nights later, the B-29s targeted Ichinomiya, Tsuruga, Utsunomiya and Uwajima. On 16 July, Hiratsuka, Kuwana, Namazu and Ōita were attacked. Chōshi, Fukui, Hitachi, Okazaki

On April 7, 1945, another precision bombing attack hit and destroyed most of the Mitsubishi Aircraft Engine Works. On May 14 and 16, 1945, there were large air raids and widespread firebombing that targeted the Mitsubishi factories and other war industries, the arsenal, railroad freight yards, and the seaport. Nagoya Castle, a national treasure which was being used as a military command post, was also hit during the May 14 raid and burned down. Also during the winter of 1944 and spring of 1945 there were random single-bomber attacks that were used as psychological warfare to disrupt the city and damage the morale of

Content:  As part of World War II, the city was bombed three times by the United States Army Air Forces (USAAF) between April 1945 and July 1945. The most serious attack was an area bombing with Napalm bombs on April 15, 1945. The attacks destroyed around 35% of the urban area and claimed 1,520 dead and 8,759 injured. The attacks burned down 9.3 km2 of the city (see Bombing of Tokyo).
