Source-derived summary

Nagata Yasujirō (永田泰次郎; January 26, 1867 – January 19, 1923) was a Japanese admiral who was Commander of the Interim Southern Islands Defense Unit from 1917 to 1919.

Biography

Nagata was born in Edo (present-day Tokyo) where his father was a samurai. After attending the preparatory school Keio University he graduated from the 15th class of the Imperial Japanese Naval Academy in 1886. His classmates was the future Prime Minister Okada Keisuke and admirals Takeshita Isamu and Takarabe Takeshi. He was commissioned as a lieutenant on February 20, 1895, and served as chief torpedo officer on the cruisers Hiei, Chiyoda, and Yoshino in 1899.

He received his first command, that of the destroyer Usugumo on June 22, 1900. In September of the same year, he was promoted to lieutenant commander and reassigned as naval adjutant to the Government-General of Taiwan, serving in Taiwan to March 1902. He served in a number of staff positions, and was subsequently promoted to commander on January 12, 1905. During the Russo-Japanese War, he was Admiral Tōgō Heihachirō's liaison with the civilian government in Tokyo.

He returned to sea in 1907 as executive officer on the cruiser Yakumo followed by the Iwami, and after commanding a number of destroyer squadrons was promoted to captain on October 11, 1909.

Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as japanese military personnel (1867-1923). Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated May 3, 2026. The linked authority identifier is Q11550256. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1867, 1923, 1917 and 1919.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. 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.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
