The Wikipedia article of the day for June 15, 2021 is Bombing of Yawata (June 1944).
The Bombing of Yawata on the night of 15/16 June 1944 was the first air raid on the Japanese home islands conducted by United States Army Air Forces (USAAF) strategic bombers during World War II. The attack was undertaken by 75 B-29 Superfortress heavy bombers (examples pictured) staging from bases in China. Only 47 of these aircraft dropped bombs near the raid’s primary target, the Imperial Iron and Steel Works at Yawata, and little damage was caused. Five B-29s were lost in accidents during the operation and two were destroyed by Japanese aircraft. While the raid did not achieve its aims, it raised Japanese civilians’ awareness that their country was being defeated and received unduly positive media coverage in the United States. Intelligence gathered also revealed weaknesses in Japan’s air defenses and the raid was the first of many on Japan. Yawata was attacked again on 20 August 1944. Much of the city was destroyed in a firebombing raid conducted by B-29s based in the Mariana Islands on 8 August 1945.
