Born in Kagoshima (Satsuma).

Son of a samurai family in Satsuma province, Yamamoto fought in the Boshin civil war that followed the Meiji Restoration- the Boshin War. In 1874, he graduated from the Naval Training Academy. He became one of the most influential figures in planning naval strategy during the Sino-Japanese War of 1894-1895 and in the administration of the Navy Ministry. He became navy minister in the second Yamagata Aritomo cabinet of 1898, a post he held in successive cabinets for six years.
In 1913, during the Taisho Political Crisis, Yamamoto was appointed prime minister after the collapse of the second cabinet of Katsura Taro which was a result of public uprisings. Yamamoto's cabinet, which closely cooperated with the party Seiyukai and its leader Hara Takashi, revised the administrative rule that allowed only officers on active duty to serve as army and navy ministers, which had been introduced by Yamagata Aritomo in 1898. The Siemens Incident of 1914, a scandal involving naval officers, forced Yamamoto's resignation.
In 1923, however, Yamamoto was again summoned to form a cabinet. Assuming responsibility for the Toranomon Incident, an assassination attempt on the prince regent (the later Showa Emperor) by a Japanese-Korean, Yamamoto resigned on 7 January 1924 and withdrew from politics.
