Yamamoto Tatsuo
Japanese politician (1856-1947)

Baron Yamamoto Tatsuo (山本 達雄; 7 April 1856 – 2 November 1947) was a Japanese banker and politician who was Governor of the Bank of Japan from 1898 to 1903. He was also a member of the House of Peers and served as a cabinet minister in the pre-war government of the Empire of Japan.
Early life
Yamamoto was born in Usuki, Ōita Prefecture. He was the younger son of a samurai family of Usuki Domain. After the Meiji Restoration, at 19 he moved to Osaka, and at 22 to Tokyo, where he studied at a school run by the Mitsubishi company.
Career
Yamamoto's first employment was as a teacher at the Osaka University of Commerce. At 26, he was appointed its principal.
In 1883, Yamamoto turned towards commerce, and obtained a position at the Mitsubishi-affiliated shipping firm Nippon Yusen, in which he rapidly rose through the corporate ranks. In 1890, he joined the Bank of Japan (BOJ), and in 1895 was appointed the chairman of the Yokohama Specie Bank. In April 1896, in order to better acquaint himself with issues pertaining to the gold standard, he travelled to England, and while still in England the following year, was appointed to the board of directors of the Bank of Japan.

Why this record matters
The phrase “japanese politician (1856-1947)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Biographical claims are most persuasive when dates, appointments and relationships can be traced to records created close to the events described. The source revision retrieved here is dated Jun 17, 2026. The linked authority identifier is Q458627. VIAF identifies the subject as 54044659. The Library of Congress control number is nr96004795. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1856, 1947, 1898 and 1903.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
