Another piece of info:

The attack on Pearl Harbor

7:49am - Fuchida radios his planes to attack with "To To To" code for "charge"

7:53am - Fuchida radios "Tora Tora Tora" code ("tiger") that the surprise attack on Pearl was successful.



CAPT. MITSUO FUCHIDA
(1902-1976)

So it seems that "To To To" was the attack code and not Tora Tora Tora...
