attack on Pearl Harbor
Attack on Pearl Harbor
The attack on Pearl Harbor was a surprise military strike by the Imperial Japanese Navy Air Service against the United States naval base at Pearl Harbor, Hawaii Territory, on the morning of December 7, 1941.
 The attack, also known as the Battle of Pearl Harbor, led to the United States' entry into World War II.
 The Japanese military leadership referred to the attack as the Hawaii Operation and Operation AI, and as Operation Z during its planning.
Minoru Yasui
Minoru "Min" Yasui (安井稔 , Yasui Minoru , October 19, 1916 – November 12, 1986) was a Japanese American lawyer from Oregon.
 Born in Hood River, Oregon, he earned both an undergraduate degree and his law degree at the University of Oregon.
 He was one of the few Japanese Americans after the bombing of Pearl Harbor who fought laws that directly targeted Japanese Americans or Japanese immigrants.
 His case was the first case to test the constitutionality of the curfews targeted at minority groups.
Kōkūtai
A Kōkūtai (航空隊 ) was, during World War II and in the Imperial Japanese Navy, a type of aerial combat unit, similar to the Air Groups in service in the other armies and navies of the time (called "Group" in the British Royal Air Force, "Gruppe" in the German Luftwaffe, "Groupe" in the French Armée de l'Air etc.).
 Although belonging to the Imperial Navy the Japanese Kōkūtai could be based at land or on board naval aircraft carriers and were constituted by hundreds of men and aircraft (that latters were distributed in smaller units called Hikōtai, the equivalent of squadrons).
 For example, the famous 343 Kōkūtai (a fighter group, divided in three Hikōtai) was based at land while the 652nd Kōkūtai (a bomber group) was carrier-based.
 As in general in the Imperial Japanese Navy Air Service, most pilots and aircrew members of a Kōkūtai were non-commissioned officers. Japanese American service in World War II
During the early years of World War II, Japanese Americans were forcibly relocated from their homes in the Pacific Coast states because military leaders and public opinion combined to fan unproven fears of sabotage.
 As the war progressed, many of the young "Nisei", Japanese immigrants' children who were born with American citizenship, volunteered or were drafted to serve in the United States military.
 Japanese Americans served in all the branches of the United States Armed Forces, including the United States Merchant Marines. William Forbes-Sempill, 19th Lord Sempill
William Francis Forbes-Sempill, 19th Lord Sempill AFC, AFRAeS, (24 September 1893 – 30 December 1965) was a Scottish peer and record-breaking air pioneer who was later shown to have passed secret information to the Imperial Japanese military before the Second World War.
 Educated at Eton, he began his career as a pilot in the Royal Flying Corps and then served in the Royal Naval Air Service and Royal Air Force during the First World War.
 In 1921, Sempill led an official military mission to Japan that showcased the latest British aircraft.
 In subsequent years he continued to aid the Imperial Japanese Navy in developing its Navy Air Service. Niihau incident
The Niʻ ihau incident (or Battle of Niʻ ihau) occurred on December 7–13, 1941, when Imperial Japanese Navy Air Service pilot Shigenori Nishikaichi (西開地 重徳 "Nishikaichi Shigenori") crash-landed his Zero on the Hawaiian island of Niʻ ihau after participating in the attack on Pearl Harbor.
 He was killed in a struggle with people on the island. Japanese American Citizens League
The Japanese American Citizens League (日系アメリカ人市民同盟 , Nikkei Amerikajin Shimin Dōmei ) was formed in 1929 out of existing Nisei organizations in California and Washington, and spread to become the largest and most well-known Japanese American organization in the United States.
 In its early years, it lobbied for legislation that expanded the citizenship rights of Japanese Americans, and local chapters organized meetings to encourage Nisei to become more politically active.
 During and leading up to World War II, the JACL was criticized for its decision not to use its political influence to fight the incarceration of Japanese Americans, aiding U.S. intelligence agencies in identifying "disloyal" Issei, and taking a hardline stance against draft resisters in camp.
 These issues remain a source of division within the Japanese American community and the organization itself. Japanese marine paratroopers of World War II
The Imperial Japanese Navy fielded naval paratroopers during World War II.
 The troops were officially part of the Special Naval Landing Forces (SNLF or "Rikusentai").
 They came from the 1st, 2nd and 3rd Yokosuka SNLFs.
 The 2nd Yokosuka took no part in any airborne operations and became an island defensive base unit.
 They were under the operational control of the Imperial Japanese Navy Air Service (IJNAS or "Dai-Nippon Teikoku Kaigun Koku Hombu").
 "Rikusentai" paratroopers should not be confused with the Imperial Japanese Army paratroopers, known as "Teishin". Mitsuo Fuchida
Mitsuo Fuchida (淵田 美津雄 , Fuchida Mitsuo , 3 December 1902 – 30 May 1976) was a Japanese captain in the Imperial Japanese Navy Air Service and a bomber aviator in the Japanese navy before and during World War II.
 He is perhaps best known for leading the first air wave attacks on Pearl Harbor on 7 December 1941.
 Working under the overall fleet commander, Vice Admiral Chūichi Nagumo, Fuchida was responsible for the coordination of the entire aerial attack. Japanese Americans
Japanese Americans (日系アメリカ人 , Nikkei Amerikajin ) are Americans who are fully or partially of Japanese descent, especially those who identify with that ancestry, along with their cultural characteristics.
 Japanese Americans were among the three largest Asian American ethnic communities during the 20th century, but since the 2000 census, they have declined in number to constitute the sixth largest Asian American group at around 1.3 million, including those of partial ancestry.
 According to the 2010 census, the largest Japanese American communities were found in California with 272,528, Hawaii with 185,502, New York with 37,780, Washington with 35,008, Illinois with 17,542, and Ohio with 16,995.
 Southern California has the largest Japanese American population in North America, and the city of Torrance holds the densest Japanese American population in the 48 contiguous states.
