The area of the modern city of Iwade was within ancient Kii Province. Negoroji temple was founded in the 12th century. After the Meiji restoration, the area became part of Naga District, Wakayama, and the village of Iwade was established with the creation of the modern municipalities system on April 1, 1889. Iwade was promoted to town status on August 1, 1908. On September 30, 1956 Yade annexed the neighboring villages of Yamazaki, Negoro and Kamiiwade. The five towns in Naga District other than Iwade merged on November 7, 2005 to become the city of Kinokawa. However, as the town had a population of more than 50,000 people as of the 2005 census Iwade fulfilled the requirements to gain city status by both the ordinance of Wakayama Prefecture and Local Government Law. At the request of residents, Iwade decided to gain city status alone, which was attained on April 1, 2006
