Iichirō Hatoyama (鳩山 威一郎 Hatoyama Iichirō?, November 11, 1918 – December 20, 1993) was a Japanese politician and diplomat. In 1976-1977, he was Foreign Minister under Prime Minister Takeo Fukuda. He is the son of Ichirō Hatoyama.
Hatoyama was born in Tokyo to a high-profile family. He studied at the University of Tsukuba.
Iichirō was a 1941 graduate of Tokyo Imperial University's School of Law; but despite family pressure, he resisted going into law or politics. Instead, he decided to become a public servant; but his plans were interrupted by the Pacific War. He enlisted in the Navy, and was presumed dead when the war ended.
At end of the war, Iichirō was one of 6.6 million Japanese military personnel and civilians who were stranded overseas. At the time, this was about 8 percent of Japan's entire population. These statistics provide a context for understanding what it meant that Iichirō was unable to return home until December 31, 1945.
Iichirō was the eldest son of Ichirō Hatoyama, who was the Prime Minister of Japan in 1955-1956. His grandfather Kazuo Hatoyama was Speaker of the House of Representative in the first Imperial Diet. Despite family pressure, he was interested in building a life outside the arena of Japanese politics; and his sons also grew to become independent-minded men.
His wife, Yasuko Hatoyama, is a daughter of Shojiro Ishibashi, the founder of Bridgestone Corporation. The couple have two sons. Kunio Hatoyama, like his brother Yukio, may be described as a fourth generation politician  and most recently the Minister of Internal Affairs and Communications.
In due course, Iichirō was promoted to the position of Deputy Director General in 1963; and he became Director General in 1965. He served as administrative Vice Minister in the Finance Ministry from 1971 to 1972. The position of vice minister is the highest rank in the civil service, comparable to that of "permanent secretary" in the British civil service or "undersecretary" in the civil service of the United States government. The minister is always a politician.
The capstone of his political career was the period in which he served as Foreign Minister in 1976–1977.
