US Naval code-breakers. The US Naval intelligence (code-breakers section) had begun to crack the super-encrypted Japanese Naval Code Kaigun Ango Sho D (known by US code-breakers as AN-1 and later called JN-25). Simplistically, this was a complex 'code within a code'. The Japanese coded-messages were transmitted by radio and then heard by US Military (and Allied) listening posts throughout the Pacific. These messages were sent to a central collection office within US Naval intelligence to be decoded if possible. The more messages collected, the better the chance of finding patterns that enabled decoding of small bits of messages. Because of the US Doolittle Raid of 18 April 1942, Japanese radio traffic using the JN-25 codes dramatically increased. This assisted the US code-breakers to determine that some sort of Japanese offensive was planned for the eastern part of New Guinea & the Solomon Islands. This information was used by Admiral Nimitz to position two US aircraft carriers in the area. The US intelligence information was verified by the subsequent Battle of Coral Sea from 4-8 May 1942. This validated the earlier decoding and helped the Code breakers project that the next Japanese strike would be aimed at Midway based on the latest intercepts & partial decoding. The Japanese final decision to invade & seize Midway happened on 5 May 1942. Japanese instructions went out by radio in code thereafter. Starting 14 May 1942, the US code-breakers were getting the first hints of the Japanese Midway operation. By the next week US Admiral Nimitz was fairly certain that the Japanese would attack Midway the first week in June.
What else can I help you with?
Ask us anythingIn June 1942 decoded Japanese messages alerted the US to the Japanese attack on?
Decoded Japanese military radio messages let U.S. forces know that the Japanese Navy was planning a very large attack on Midway Island, along with a smaller attack on Wake Island.
Where did the Japanese attack after Pearl Harbor?
After the attack on Pearl Harbor, the Japanese attacked various locations in the Pacific, including the Philippines, Guam, Wake Island, and Hong Kong.
Why Japanese sent part of their returning fleet to Wake Island?
The overall Japanese plan was very complicated. They were attacking in five widely separated areas, and all were to commence just as soon as the attack on Hawaii was under way. These included the naval air attack on Hawaii, an invasion of the Philippines, two invasions in southeast Asia, and an attack on Wake Island. Wake Island was a US possession and, unlike Hawaii, the Japanese intended to land troops and capture and hold the island. But their initial attack was repulsed by the Marine Defense Battalion on Wake. Part of the task force returning from Hawaii was diverted to support a renewed effort to capture Wake Island.
Was Croker Island actually attacked by the Japanese as in the movie 'Australia'?
The Japanese attacked Australia in Air raids and once they attacked Sydney harbour by sneaking mini submarines in. However there was never an attack by Japanese soldiers on Australian soil.
What does tora mean in Japanese?
In Japanese, "tora" (虎) means "tiger." The character 虎 represents the animal tiger in the Japanese language. Tigers are symbolic in Japanese culture, often representing strength, courage, and protection.
The Doolittle Raid convinced Japanese leaders to attack Midway Island?
Indirectly, yes. The Doolittle attack in April, 1942, showed that the US carriers were as much of a threat to Japan as they had thought. The attack on Midway (June 4-7, 1942) was planned as a way to draw out the US carriers, since Pearl Harbor was now heavily defended. Unfortunately, the US, alerted to the Japanese movements, turned the tables with a trap of their own, sinking 4 Japanese carriers at the cost of one of their own, the Yorktown.

What time did the Japanese launch their planes to attack Midway Island?
0600 dawn
What strategy did the u.s. use to attack the Japanese on selected islands?
"Island Hopping" .
What island in the north Pacific Ocean was an American victory over Japan?
This was a failed attack against the US base at Midway. The island was northwest of Hawaii. The Japanese raid on the island was foiled because the US had broken the Japanese military codes and knew when the attack was planned. The Japanese were caught off guard and lost the battle there.

Why did the Japanese attack changde?
IF you mean why did Japan attack CHINA; the Japanese attacked China, because Japan is an island nation with few natural resources, and China has a lot of natural resources, so Japan attacked China to get it's resources to help the Japanese people.
Why did the leaders of the us navy believe a full scale naval attack against Pearl Harbor was impossible?
They believed it was impossible because they thought that there was no way for an entire Japanese fleet to sneak all the way over to Hawaii undetected. In addition, the waters at Pearl Harbor were relatively shallow. So, torpedoes were out of the question. But the Japanese were always a few steps ahead. They added wooden fins to their torpedoes to allow them to be used in shallow water. They also managed to hide their fleets, making it seem as if they completely disappeared. The US Navy & US Army leaders did think an attack was possible but not likely. They thought that Japan would likely attack the Philippines, Guam, Wake Island, and Midway Island. They took military precautions for those possibilities, but not as much thought was paid to the idea that Japan would attack Hawaii also. The actual Japanese attack against Hawaii on December 7, 1941 was not a full-scale naval attack. The surprise attack was an attack by carrier-based aircraft, by midget submarines & fleet submarines only.
What was true of the Battle of Iwo Jima?
Almost all of the Japanese fought to their deaths.
Was Croker Island actually attacked by the Japanese as in the movie 'Australia'?
