He was a son of Mizuno Tadamasa, and brother of Mizuno Tadashige.

In 1542, Nobumoto sided with Oda Nobuhide, but later served to Tokugawa Ieyasu.

In 1543, he succeeded his father as lord of Kariya Castle.

In 1554, the Imagawa clan came to the west and built the Muraki Castle in the southeast of Owari, besieging Mizuno Nobumoto at his castle of Ogawa. Mizuno Nobumoto informed about the situation to Oda Nobunaga. Later, Nobunaga marched his army north and attacked the Imagawa forces in the Battle of Muraki Castle.

In 1576, under Ieyasu, he was assigned to defend Kariya Castle. However, in that same year, he betrayed Tokugawa Ieyasu and was killed.
