query: How long was Takeo Fukuda prime minister of Japan?
passage: Takeo Fukuda
Fukuda was married and had five children: three sons and two daughters.[3] His eldest son, Yasuo Fukuda, after the sudden resignation of Shinzō Abe, became Prime Minister in September 2007, and remained in that office for one year, making him the first son of a Japanese prime minister to become a prime minister himself.[4] In addition, Prime Minister Junichiro Koizumi began his political career as a secretary to Fukuda, and the two were very close in their political and personal lives from the 1970s onward (Fukuda was the best man at Koizumi's wedding).
passage: Banri Kaieda
In January 2011, he was appointed to head the Ministry of Economy, Trade and Industry by Prime Minister Naoto Kan. The Fukushima disaster in March 2011 made evident numerous missteps within the ministry, and Kaieda stepped down as economy minister in August in order to take responsibility. He had been under intense pressure to resign from the Liberal Democratic Party, and was brought to tears on the Diet floor following 20 minutes of berating from LDP legislator Ryosei Akazawa days earlier.
