Archaeologists have found numerous Kofun period remains at numerous locations in what is now Saiwai-ku, indicating a long period of human settlement. Under the Nara period Ritsuryō system, it became part of Tachibana District Musashi Province. In the Edo period, it was administered as tenryō territory controlled directly by the Tokugawa shogunate, but administered through various hatamoto, and was the center of a prosperous farming area adjacent to Kawasaki-juku, a post station on the Tokaido highway connecting Edo with Kyoto. After the Meiji Restoration, the area urbanized due to its proximity to Kawasaki Station on the Tokaido Main Line. Saiwai Village within Tachibana District in the new Kanagawa Prefecture was created on April 1, 1889 through the merger of eight smaller hamlets. In the early twentieth century, the area was dominated by factories; notably Meiji Sugar and Toshiba. The area was largely destroyed by the Great Kanto earthquake of 1923, but was soon rebuilt. The area was annexed by the neighboring city of Kawasaki in two stages in 1927 and in 1937. The area was heavily damaged by American bombing during World War II.

Saiwai Ward was established with the division of Kawasaki into wards on April 1, 1972.

The economy of Saiwai Ward continues to be dominated by industry, with Toshiba, Canon, Pioneer Corporation, and Hitachi. A number of companies are headquartered in Sawai Ward, including the Japanese subsidiaries of Dell Computer, Toys "R" Us as well as Mitsubishi Fuso Truck and Bus Corporation, Universal Shipbuilding Corporation, and Fuji Sash.
