History

The area around Ena was part of traditional Mino Province, and the name of "Ena" appears in Nara period records, including the Nihon Shoki. During the Edo period, it was mostly controlled by Iwamura Domain, and Ōi-juku developed as a post town on the Nakasendō highway connecting Edo with Kyoto. During the post-Meiji restoration cadastral reforms, the area was organised into Ena District, Gifu.

The city was founded on April 1, 1954, by the merger of two towns (Oi and Osashima) and six villages (Tōnō, Sango, Takenami, Kasagi, Nakano, and Iiji), all from Ena District. On October 25, 2004, Ena absorbed the towns of Akechi, Iwamura, Kamiyahagi and Yamaoka, and the village of Kushihara (all from Ena District) to create the expanded city of Ena.

Ena has a mayor-council form of government with a directly elected mayor and a unicameral city legislature of 18 members.
