Kōyō Ishikawa (石川 光陽, Ishikawa Kōyō; July 5, 1904 – December 26, 1989) was a Japanese photographer. As an officer of the Tokyo Metropolitan Police Department, he was one of the few known photographers of the immediate aftermath of the U.S. bombings of Tokyo in World War II, since strict regulations prohibited civilians from taking pictures of war damage.
