Fukuda Doctrine
Takeo Fukuda was an expert in economics. He took on the role of an ‘economic prime minister’ under Miki's administration from 1974 to 1976. During this time, he established the Ministerial Conference on Economic Measures, enabling cross-ministry and agency talks on finance, wage and labor issues.
Fukuda subsequently became the 67th prime minister of Japan, lasting for only one term from 1976 to 1978. However, he was not forced out of office before he had gotten two major diplomatic reforms executed. Under Fukuda cabinet, Japan conducted an omnidirectional peace diplomacy, and signed Japan-China Treaty of Peace and Friendship in 1978. He pushed forward Japan's pacifistic position while making an effort to strengthen relations with Asian countries.
Mizuho Fukushima
Fukushima was also Minister of State for Consumer Affairs and Food Safety, Social Affairs, and Gender Equality in Prime Minister Yukio Hatoyama's cabinet (16 September 2009 – 28 May 2010); the SDP was the junior partner in the DPJ-led government coalition. However, in May 2010 disagreements over the issue of the Marine Corps Air Station Futenma led to the sacking of Fukushima from the cabinet on Friday May 28, and the SDP subsequently voted to leave the ruling coalition.
