Count Date Munemoto (????, 24 August 1866 – 27 January 1917) was a Bakumatsu period Japanese samurai, and the 14th and final daimyo of Sendai Domain in the Tohoku region of northern Japan, and the 30th hereditary chieftain of the Date clan.
Munemoto fourth son of Date Yoshikuni.
In 1868, following the defeat of the Ouetsu Reppan Domei in the Boshin War of the Meiji Restoration, Yoshikuni resigned his offices and went into voluntary retirement and seclusion in Tokyo.
The new Meiji government permitted the two-year-old Munemoto to become daimyo of Sendai Domain, but penalized the domain severely for its participation in the rebellion by reducing its kokudaka from 620,000 to 280,000 koku.
The actual kokudaka of the reduced Sendai Domain was actually even less, and has been estimated at only 100,000 koku.
His childhood name was Kamesaburo (???).
In 1869, the office of daimyo was abolished by the new government, and Munemoto was made appointive imperial governor of Sendai.
In 1870, he yielded this position to his adoptive brother Date Muneatsu, but retained the post of clan leader.
He was married to the daughter of Matsura Akira, daimyo of Hirado Domain, by whom he had one daughter.
In 1884, Munemoto was created count (hakushaku) in the new Japanese kazoku peerage system.
He was advanced to Third Court Rank in 1911 and Second Court Rank in 1917.
On his death in 1917, the post of clan chieftain went to his younger brother Date Kunimune.
