Yasuoka is known to have worked himself and his staff very long hours. He was one of the key participants in the launch of Fukuda's administration in 2007. Yasuoka also chaired the LDP's Constitution Research Commission.

An avid jogger and swimmer, Yasuoka repeatedly swam the 2.1 km-wide Kinko Bay in Kagoshima Prefecture.
