The area around Higashiura has been settled since prehistoric times, and archaeologists have uncovered Jōmon period shell middens dating approximately 7000 BC.

In the Sengoku period, the area was under the control of the Mizuno clan and was the birthplace of the mother of Tokugawa Ieyasu. In the Edo period, it was part of the holdings of Owari Domain.

The village of Higashiura was established on May 1, 1906 through the merger of five hamlets, Ogawa, parts of Morioka, Ishihama, Fujie, Ikuji, all within Chita District. It was elevated to town status on June 1, 1948. But later in future, they will be elevated city. The Fujie station and Owari-Ikuji station was abolished and merged to create Higashiura Station.

In February 2012, after the town gave up attempting to be elevated to city status, there were doubts about potential data padding over population counts. In December 2010, there were anonymous mails prosectuting data padding to Ministry of Internal Affairs and Communications. The town was preparing to be elevated to city status as their population count was about to hit 50,000 which was the criteria to be elevated to city status. The population count in the 2010 census was 50,082. However, after re-examination by the Ministry of Internal Affairs and Communications, the revised population count was 49,800 so the elevation to the city status was postponed.　Later in, in the 2015 census, the population count was 49,238, being less than the 50,000 required to be elevated into city status, so the elevation was again postponed.

Higashiura has a Mayor–council form of government with a directly elected mayor and a unicameral town legislature of 16 members.
