New Controversy On Pearl Harbor Messages Likely

By Thomas O'Toole

December 6, 1981

When U.S. codebreakers here translated an intercepted secret radio cable from the Japanese Foreign Office in Tokyo to the embassy on Massachusetts Avenue Nov. 19, 1941, shock waves rolled across town, all the way to the White House.

"In case of emergency," the translated cable read in part, "the following warning will be added in the middle of the daily Japanese language shortwave news broadcast. This signal will be given in the middle and at the end as a weather forecast, and each sentence will be repeated twice.

"When this is heard, please destroy all code papers, etc. This is to be a completely secret arrangement."

At once, the nation's six Army and two Navy radio intercept stations were alerted to watch for Japan's message that trouble was about to start. Intelligence officers here made it a top priority for all radiomen to listen for the warning message from Japan.

The Japanese repeated the warning in a second secret message to Japan's embassies throughout the world the morning of Dec. 4, and that also was intercepted by U.S. codebreakers. It said:

"When crisis leading to worst arises, following will be broadcast at end weather reports: One, East Wind Rain, war with United States; two, North Wind Cloudy, war with Russia; three, West Wind Clear, war with Britain, including attack on Thailand, Malaya and Dutch Indies.If spoken twice, burn codes and secret papers."
