was the 9th and final daimyà  of Hasunoike Domain in Hizen Province, Kyà «shà «, Japan (modern-day Saga Prefecture). Before the Meiji Restoration, his courtesy titles were title of Kai no Kami and junior 5th, lower grade court rank (ju go i no ge, å¾ÂäºÂä½Âä¸Â).
Naotada was the eldest son of Nabeshima Naotomo, the 8th daimyà  of Hasunoike. His mother was the daughter of Nijà  Harutaka. He attended the domain academy as a child, and on the retirement of his father on July 28, 1848, he became the 9th daimyà  of Hasunoike Domain.
In 1854, he was ordered by the Tokugawa shogunate to take responsibility of the defenses of the Nagasaki area against possible incursions by foreign ships, and was forced to raise and train troops, and build coastal defense fortifications. This greatly strained the already precarious finances of the domain, which could only be resolved by placing the domain into great debt. In 1864, he was ordered to participate in the First Chà Âshà « expedition, and contributed 1000 soldiers to the Tokugawa army. By order of his retired father, he also dispatched troops to Kyoto to assist the Tokugawa forces in keeping public order.
During the Boshin War of the Meiji Restoration, he switched sides to the Satchà  Alliance and dispatched HasunoikeâÂÂs forces under the command of his younger brother, Ishii Tadami, against the à Âuetsu Reppan Dà Âmei at Akita in support of Emperor Meiji.
In 1869, he was appointed "domain governor" as the title of daimyà  was abolished, and with the abolition of the han system and subsequent merger of Hasunoike into the new Saga Prefecture in 1871, he moved to Tokyo. In 1884, his adopted son became a viscount (shishaku) under the kazoku peerage. In April 1885, he was granted the courtesy title of senior 5th rank (shà  go i, æ£äºÂä½Â). He died at the clanâÂÂs Azabu residence in 1891, and his grave is at the Azabu Cemetery in Tokyo.
