According to the Harima no Kuni Fudoki, the origin of the name "Tatsuno" was that upon the death of Nomi no Sukune in Ibo District (now in the city of Tatsuno), many came from Izumo and used rock from the Ibo River to make a grave, standing stones in a row on the plain.

The Tatsuno area was part of ancient Harima Province and was an important location for traffic on the Izumo Kaidà  highway running along the Ibo River, and was the location of Kinoyama Castle, a stronghold of the Akamatsu clan in the Muromachi period. After Oda Nobunaga gained supremacy during the Sengoku period, the area became the territory of the Ikeda clan, who ruled Himeji Domain in the early Edo period. Following Ikeda Toshitaka's death, his lands were divided by the Tokugawa shogunate and Honda Masatomo, was installed as daimyà  of the newly created Tatsuno Domain.

The castle town's area from the early modern period is extant today in what is now the "old Tatsuno-chà  area,â which still contains samurai residences and white-plastered earthen storehouses, giving the city the moniker of"Little Kyoto of Harima".
