Answer:
“Climb Mt. Itaka”
Step-by-step explanation:
The phrase that the Japanese used to proclaim to troops that they should go forward and attack Pearl Harbor was “Climb Mt. Itaka”. With this code, the Japanese started the attack on November 19th in 1941. Pearl Harbor attack was what finally tipped the United States to declare the war.
The phrase said to Japanese tropes that meant they should return was “Climb Mt. Tsukuba”.
