The area of modern-day Hidaka was part of ancient Koma District, Musashi Province, mentioned in records dating from 716 AD as a place of resettlement for refugees from the Tang invasion of the Kingdom of Goguryeo on the Korean peninsula in 668 AD. During the Edo period, the area developed as Takahagi-shuku, a post station on the Nikkō Wakiōkan highway linking Edo with Nikkō. The three villages of Komagawa, Koma and Takahagi were established within Koma District with the establishment of the modern municipalities system on April 1, 1889. In 1896 Koma District was abolished, becoming part of Iruma District. On February 11, 1955 Komagawa and Koma merged to create the town of Hidaka. Takahagi joined Hidaka on September 20, 1956. Hidaka was elevated to city status on October 1, 1991.
