Isoroku Yamamoto Biography

(Japanese Naval Officer Who Conceived The Pearl Harbor Attack in 1941)

Birthday: April 4, 1884 (Aries)

Born In: Nagaoka, Niigata, Japan

Isoroku Yamamoto was an able Japanese Naval Chief who played a vital role in the Pearl Harbor attack that made Japan victorious in the early phase of World War II. He was educated at Harvard and was good at English. His word of opposition against the invasion of Manchuria and his personal apology to the American Ambassador for the attack of Japanese fighter planes on the U.S. boat on the Yangtze River incurred him the wrath of right-wing Japanese who planned to assassinate him. He also strongly disapproved the Tripartite Pact that Japan had made with Nazi Germany and forewarned the Japanese Prime Minister Fumimaro Kondoye of the tremendous power of the United States. He was the mastermind behind the successful Japanese Pearl Harbor attack against the United States fleet. Though he was personally not in favor of war against the Americans, he discharged his duties sincerely as a true patriot who wished to be at the side of his country at its odds and ends. He enjoyed playing games like Shogi, a Japanese chess game, Go, bridge and poker. It is an irony that this pro-American was killed by the Americans to avenge the harm done to them at the Pearl Harbor.
