Yasuo Fukuda
Fukuda was born in Takasaki, Gunma, the eldest son of politician (later the 67th Prime Minister) Takeo Fukuda. He grew up in Setagaya, Tokyo, attending Azabu High School and graduating from Waseda University in 1959 with a degree in economics. After university, he joined Maruzen Petroleum (now part of the Cosmo Oil Company). He was only minimally involved in politics over the next seventeen years, working his way up to section chief as a typical Japanese "salaryman". He was posted to the United States from 1962-64. While his father Takeo Fukuda was prime minister from 1976–78, Yasuo became a political secretary. From 1978 to 1989, he was a director of the Kinzai Institute for Financial Affairs, serving as a trustee from 1986 onward.
Kozo Yamamoto
The general election of 2009 saw both Takeda and Yamamoto vying for the LDP slot of Fukuoka's 11th precinct. Yamamoto ultimately took the PR spot for Kyushu, and even with the political turnaround of the Democratic Party of Japan winning 221 of 300 electoral districts, both Takeda and Yamamoto won their respective seats. In 2012, Yamamoto successfully ran under the LDP in the 10th precinct of Fukuoka. He continued his electoral success in the same precinct in 2014, and was appointed his ministerships in 2016.
