May 25th is the 70th anniversary of the Great Yamanote Air Raid. This was the fifth and final low-altitude night incendiary raid on urban areas of Tokyo by the US Army Air Forces. The first of these five massive firebombing raids was the Great Tokyo Air Raid of March 10, 1945. On that night, 279 B-29s dropped 1,665 tons of incendiaries on the Shitamachi district of the capital. By dawn, more than 100,000 people were dead, over a million were homeless, and 15.8 square miles of Tokyo had been burned to the ground.
