Hiezu, unlike other areas of Tottori Prefecture, has no evidence of ancient settlements. The area was inhospitable to early settlement due to coastal flooding and its sandy soil. The area of present-day Hiezu appears in a Heian-period dictionary compiled in 934, the Wamyō Ruijushō, as part of the village of Mino in Aimi District. Hiezu became part of the Kayashima shōen estate after this period, but all three areas of the village were destroyed by fire in 1571 in a regional conflict during the Sengoku period (1467 – 1573). By 1617 the village came under the control of the Ikeda clan, which controlled Hiezu as part of the Tottori Domain through the Edo period (1603 – 1868). The present-day village of Hiezu was formed by the merger of the villages on Hiezu, Tomiyoshi, and Imayoshi in 1889. The residents of Hiezu rejected a referendum on a merger with the city of Yonago in 2006. Hiezu, despite its small size, is the only village in Tottori Prefecture and remains an autonomous municipality.

Heizu has a mayor-council form of government with a directly elected mayor and a unicameral village council of 10 members. Heizu, collectively with the other municipalities of Saihaku District, contributes three members to the Tottori Prefectural Assembly. In terms of national politics, the village is part of Tottori 2nd district of the lower house of the Diet of Japan.
