Minoru Genda (源田 実 Genda Minoru , 16 August 1904 – 15 August 1989) was a well-known Japanese military aviator and politician. He is best known for planning the Pearl Harbor attack.
Minoru Genda was the second son of a farmer from Kake, Hiroshima Prefecture, north of the actual city of Hiroshima. Two brothers were graduates of Tokyo University, another brother graduated from Chiba Medical College, and his youngest brother entered the Army Academy. Genda graduated from the Imperial Japanese Naval Academy in 1924 and then took flight training for 11 months in 1928–1929, graduating with honors to become a fighter pilot.
Early military service
Genda was assigned to the aircraft carrier Akagi in 1931. He was well known in the navy and in 1932 Genda formed an aerobatic demonstration team at Yokosuka, leading a division of biplanes around the country, conducting demonstrations and aerobatics. Known as "Genda's Flying Circus", the team, consisting of Genda, Yoshita Kobayashi and Motoharu Okamura, using Nakajima A2N Type 90 fighters, was part of a public relations campaign to promote naval aviation. He gained combat experience with the Second Combined Air Group during the Second Sino-Japanese War from the autumn of 1937, was senior flight instructor for the Yokosuka Air Group in 1938.
Genda was one of the world's first naval officers to realize the potential of massing aircraft carriers to project air power. In the 1930s the aircraft carrier was a new and untested weapons system. Most naval strategists and tacticians of the time conceived of single carriers launching raids on enemy targets, or sailing with a fleet to provide air cover against enemy bombers. Genda understood the potential of massed air raids launched from multiple aircraft carriers steaming together.
An air power advocate from the time he attended the Japanese Naval Academy, Genda urged Japan's pre-war military leaders to stop building battleships (which he believed would be better used as "piers" or scrap iron) and concentrate on aircraft carriers, submarines, and supporting fast cruisers and destroyers. Above all, Genda thought that modern and large naval air fleet would be necessary for survival if Japan was ever to fight a war with the United States and the United Kingdom as well as their allies.
Pearl Harbor and World War II
The Pearl Harbor attack plan which was ultimately utilized by Japanese Admiral Isoroku Yamamoto was essentially the work of Lieutenant Commander Genda, with important contributions by others. He also recommended Mitsuo Fuchida, his classmate at the Japanese Naval Academy, to lead the Pearl Harbor attack.
Yamamoto had become acquainted with Genda in 1933 when he served aboard the carrier Ryūjō. Yamamoto initially conceived of a one-way attack on Pearl Harbor from 500 to 600 miles (800 to 970 km) away. In his scheme, returning aircraft would ditch in the ocean off Oahu and the pilots would be picked up by destroyers and submarines. Yamamoto was focused on smashing the U.S. Pacific Fleet and sinking as many battleships as possible. Conventional American and Japanese naval doctrine held that battleships were the instrumental tool of naval supremacy, so it was believed that the destruction of several of these ships would shift the balance of naval power in Japan's favor.
In summer 1940 at the age of 36, Genda, was fortunate to be chosen by the Japanese Naval Department to travel abroad as a military attaché to obtain first-hand military accounts of German air offensives and British defensive measures during the Battle of Britain. His assessment of the Royal Air Force (RAF), Hawker Hurricane Mk I and Supermarine Spitfire Mk I fighters against the German Messerschmitt Bf-109E "Emil" later provided evidence that the Japanese Mitsubishi A6M Zero Model 21 could easily outmaneuver these European aircraft. The carefully recorded details were secretly documented during his brief tour in London and were hand-carried by Genda during his return trip to Japan for naval department studies. His official trip was in accord with British-Japanese naval accords authorizing official military attaché visits to the war front to observe and document military operations. Genda's European trip provided added stimulus for Japanese strategic naval studies and exercises to discover weaknesses and formulate tactics that were later used against the U.S. On his return to Japan, he was assigned to the First Carrier Division and met with Yamamoto in early February 1941, during which time Yamamoto presented some ideas for attacking the U.S. Pacific Fleet. Genda warmed to his ideas. Genda had previously considered an attack on Pearl Harbor in 1934 and had discussed the possibility then with Takijirō Onishi. Genda emphasized to Yamamoto that "secrecy is the keynote and surprise the all-important factor." Genda felt that the task was "difficult, but not impossible" and began working on the details of the plan. Genda favored an all-out attack using six aircraft carriers for an overpowering air strike. Genda was responsible for much of the training, especially in the new tactics of shallow-water torpedo use, effective use of level-bombing by tactical aircraft, and coordinating several aircraft carriers simultaneously. He played a key role in persuading IJN leaders to name Mitsuo Fuchida, his classmate at the Japanese Naval Academy, as the leader of the air attack.
The surprise attack on Pearl Harbor resulted in a lopsided victory, with 12 American warships sunk and over 180 American aircraft destroyed. The main Japanese fleet suffered no ship losses and 29 aircraft lost, losses that the Japanese considered acceptable. In the following first six months of the Pacific War the Imperial Japanese carrier units ranged across the Pacific and Indian oceans causing major damage to Allied forces and bases. Later, the Battle of Midway brought this phase of the Pacific War to an end, as four of Japan's six heavy carriers were sunk. The Pacific War ground on for three more years.
Genda served with distinction during World War II and personally participated in combat. He was a noted naval aviator and fighter pilot with over 3,000 flight hours. He organized an elite Japanese air unit (the 343 Kokutai) near the war's end as an alternative to the suicidal kamikaze units. Genda believed that even late in the war Japanese pilots were capable of fighting experienced American pilots on equal terms if properly trained and supplied with state-of-the-art aircraft. He personally felt that the Kawanishi N1K2-J Shiden-Kai (Allied code name, "George") was equal to the American F6F Hellcat and F4U Corsair. This unit had some success against American aircraft and fought with distinction.
Genda documented his World War II experiences in a revealing autobiography, published in Japan.
Genda's military career came to a halt with the Imperial Japanese Navy's dissolution after the war ended.
Genda returned to active duty in 1954 as a member of the newly established Japan Air Self-Defense Force (JASDF), eventually rising to the rank of general and later the chief of staff. He also test-flew the Lockheed P-80 Shooting Star in the U.S. during this period.
In late 1950s, Genda, as the JASDF's deputy chief of staff, was involved in the political turmoil surrounding the acquisition of a successor to the F-86 Sabre then in service. The JASDF and the Defense Agency wanted the Grumman F-11 Super Tiger, but heavy lobbying by Lockheed—including alleged bribery, through the shadowy underworld figure Yoshio Kodama—of key LDP politicians, including Finance Minister Eisaku Sato and Policy Affairs Research Council chairman Ichiro Kono, led to the adoption of its own contender, the F-104 Starfighter. Genda functioned as Sato's front man in uniform, openly criticizing the Grumman design and working to steer the selection in favor of the Lockheed aircraft. In August 1959, Genda became the JASDF chief of staff, with the blessing of Sato, his political patron. In his new capacity, he finalized the adoption of the Lockheed jet over the objections of his subordinates.
After retiring from the military in 1962, he ran for and was elected to the upper house of Japan's legislature, the House of Councillors, as a member of the Sato Faction within the Liberal Democratic Party. He was the first of several former SDF officers who entered politics under the auspices of the Sato Faction, mostly at the far right end of the Japanese political spectrum. He remained influential in politics for more than 20 years, as a leading member of the Defense Division of the LDP's Policy Affairs Research Council, often representing the hardline nationalist position advocating abrogation or curtailment of Article 9 of the postwar Japanese Constitution and open remilitarization of the armed forces. He is particularly well known for his fierce opposition, along with 12 other far-right LDP Diet members, to Japan's ratification of the Nuclear Non-Proliferation Treaty during the 1974–1976 session of the Diet, on the grounds that Japan might one day need to acquire its own nuclear arsenal.
Genda died on 15 August 1989, exactly 44 years to the day after the Japanese surrender in World War II, and just one day short of his 85th birthday. He was married and had three children.
In popular culture
Genda served as an uncredited technical adviser in the making of the 1970 film Tora Tora Tora. In the film, the role of Genda was portrayed by Tatsuya Mihashi.
Genda was portrayed by Canadian actor Robert Ito in the 1976 film Midway, and by Japanese-American actor Cary-Hiroyuki Tagawa in Touchstone Pictures' 2001 film Pearl Harbor.
Alternative-history writer Harry Turtledove used Genda as the primary Japanese protagonist in his fictional account of an invasion of Oahu following the Pearl Harbor attack in his books Days of Infamy and End of the Beginning.
