All of what is now Minami Ward was part of the domains of the Owari Domain during the Edo period (except for two villages which belonged to Imao Domain of Mino Province). After the Meiji Restoration, the area was transferred to the new Nagoya Prefecture, which later became part of Aichi Prefecture. A “Minami Ward” was one of the original wards, with the division of the city of Nagoya into wards on April 1, 1908; however, none of present-day Minami Ward was within the geographical extent of the original Minami Ward. On August 22, 1922, Minami Ward annexed the neighboring town of Yobitsuki and the village Kasadera from Aichi District. On October 1, 1937 the city of Nagoya was re-divided into ten wards, with the original Minami Ward divided into the new Minami Ward, plus Atsuta Ward, Nakagawa Ward, Minato Ward, and part of Showa Ward. In 1959, the Isewan Typhoon caused severe damage to the area.

Minami Ward was traditionally known for its production of sea salt and edible seaweed (green laver). During the post-World War II period, the area developed into a center for heavy industry, including a large factory operated by Mitsubishi Motors. The Mitsubishi plant closed in the year 2000.
