Sunao Sonoda (園田 直 Sonoda Sunao , 11 December 1913 – 2 April 1984) was a leading Japanese Liberal Democratic Party (LDP) politician who served as foreign minister and health and welfare minister of Japan. He was called "flying foreign minister" due to his active diplomacy in increasing the role of Japan when he was in office. He was one of the significant figures in normalizing the relations between Japan and China.
Early life 
Sonoda was born in Kumamoto prefecture on 11 December 1913.
Sonoda joined the Japanese army in 1938, and served both in China and in the Pacific area during World War II. More specifically, he was commander of a kamikaze squad during the war. In 1947, Sonoda was elected to the House of Representatives, the lower house of the Diet, being a member of lower house for Kumamoto Prefecture. He was originally a member of the Democratic Party. Then he became a member of the Liberal Democratic Party (LDP) when the Democratic Party joined the Liberals.
In the 1950's, he was special envoy of the LDP. He served as parliamentary vice-foreign minister in 1955, and actively involved in normalizing the relations between Japan and the USSR. However, in 1960, he resigned from the LDP due to his objections to the ratification of the US-Japan mutual security treaty.
In addition, Sonoda was chief cabinet secretary in the cabinet of Takeo Fukuda who was in office from 1976 to 1978. Sonoda was part of the faction headed by Fukuda in the 1970s. However, he later joined the faction headed by Masayoshi Ōhira.
Minister of foreign affairs 
Sonoda served as minister of foreign affairs three times: in the cabinet of prime minister Takeo Fukuda from November 1977 to December 1978, in the cabinet of prime minister Masayoshi Ohira from December 1978 to November 1979, and in the cabinet of prime minister Zenko Suzuki from 17 May to 30 November 1981.
During his first term in the ministry of foreign affairs, Japan signed the treaty of peace and friendship with China. This treaty formed the basis of the relationships between two countries. Sonoda represented his country at the signature of this treaty in Beijing in 1978. Sonoda was secondly appointed foreign minister to the cabinet of Masayoshi Ohira who kept this and other three ministeries for his own faction. When in office for the second time, Sonoda visited five African countries in July 1979, including Tanzania, Nigeria, Kenya, Ivory Coast and Senegal.
On 17 May 1981, Sonoda was appointed by then prime minister and his close friend Zenko Suzuki as foreign minister for the last time due to unexpected resignation of the former foreign minister Masayoshi Ito. Sonoda called for adopting the omnidirectional diplomacy and unlike his two precedessors, issued entry visas to Soviet economic delegations. Sonoda was replaced by Yoshio Sakurauchi who was appointed foreign minister by prime minister Zenko Suzuki on 30 November 1981. The reason for Sonoda's removal from his post was his blunt remarks concerning U.S. policies in June 1981 as well as his other statements detrimental to Japan's relations with South Korea.
Personal life 
Sunao Sonoda married twice. His son from the first marriage, Hiroyuki Sonoda, ran for his father seat in Kumamoto Prefecture in the general elections of 1986. Sonoda'a second wife, Tenkoko Sonoda, also tried to take over her husband's seat in the same election after his death. Tenkoko Sonoda was a member of the Diet during her marriage. They married after World War II and had two children.
