Early life and family Hatoyama comes from a prominent Japanese political family which has been likened to the Kennedy family of the United States. Hatoyama, who was born in Bunkyō, Tokyo, is a fourth-generation politician. His paternal great-grandfather, Kazuo Hatoyama, was speaker of the House of Representatives of the Diet of Japan from 1896 to 1897 during the Meiji era.

As Prime Minister, he restored diplomatic relations with the Soviet Union, which cleared the way for Japan's membership in the United Nations. Hatoyama is the son of Iichirō Hatoyama, who was Foreign Minister for a time. His mother, Yasuko Hatoyama, is a daughter of Shojiro Ishibashi, the founder of Bridgestone Corporation and heir to his significant inheritance. Yasuko Hatoyama is known as the "Godmother" within the Japanese political world for her financial contributions to both of her sons' political ambitions.
