“Miyoshi" as a local place name appears in documents in the Edo period.

Miyoshi Village was created within Nishikamo District, Aichi Prefecture on October 1, 1889, with the establishment of the modern municipalities system in the early Meiji period.

Miyoshi merged with neighboring villages in 1906 to reach its present geographic borders and was raised to town status on April 1, 1958.

During 2003–2005, discussions were held to merge Miyoshi with the city of Toyota, but the merger proposal was strongly opposed by the majority of the inhabitants of Miyoshi.

As a result, the merger did not take place, and instead Miyoshi was elevated to city status on January 4, 2010.

With its change in status, Miyoshi changed the spelling of its name from kanji (三好) to hiragana (みよし)

Miyoshi has a mayor-council form of government with a directly elected mayor and a unicameral city legislature of 20 members. The city contributes one member to the Aichi Prefectural Assembly. In terms of national politics, the city is part of Aichi District 11 of the lower house of the Diet of Japan.
