Date Munenari (伊達 宗城, DAH-tay; September 1, 1818 – December 20, 1892) was the eighth head of the Uwajima Domain during the Late Tokugawa shogunate and a politician of the early Meiji era.
He returned to prominence in the subsequent years of political maneuvering in Kyoto, as a member of the conciliatory kōbu-gattai (公武合体 union of court and bakufu) party.
Late in Bunkyū 3 (1863), as a proponent of kōbu-gattai, he was made a member of the imperial advisory council (sanyō-kaigi 参与会議), together with Matsudaira Katamori and other like-minded lords.
[2] After the fall of the shogunate in 1868, Munenari took an active role in the new imperial government; Uwajima as a domain was also deeply involved in the military campaign of the Boshin War (1868–1869).
In 1871, representing the Japanese government, he signed the Sino-Japanese Friendship and Trade Treaty (Nisshin shukō jōki (日清修好条規)) with Li Hongzhang, a viceroy of Qing Dynasty China.
