“Here, leaders of Japan’s combined fleet made plans for the fiercest battles, including those of Leyte Gulf, Iwo Jima, and Okinawa  from late 1944 to the war’s end 
in August 1945. They knew when kamikaze pilots crashed to their deaths when signals from their planes stopped. They cried when they monitored cables from 
officers aboard the famed battleship Yamato as it came under heavy U.S. fire and sank off southern Japan.

“Hisanao Oshima, who was there from February to May 1945 with a communications crew monitoring Morse code, still cannot forget the moments when he lost
signals from kamikaze fighters. ‘The sound stops, and that means he crashed. I just cannot get that out of my head,’ he said in an interview with public broadcaster
NHK.

“ [ photo ] Journalists walk in underground tunnels that Japan’s Imperial Navy once used as secret headquarters underneath the Hiyoshi Campus of Keio University
in Yokohama....
“Hundreds of hangars, tunnels, and other wartime remains still exist in Japan, but many have been abandoned as interest has waned.”

Comment: Morse signals from kamikaze plans would have to refer to multiplace planes, such as torpedo bombers or bombers. I do think kamikaze planes
were in the great majority, single place fighter planes. The stopping of signals could also have marked the plane’s being attacked by U.S. screening fighters.

I read in a book of Japanese Navy pilot accounts, this is the late-war way of determining where the Allies were. Weather planes were sent out, and transmitted
position reports more or less continuously. When the signals ended, that marked that the scouts had encountered Allied forces.
