Climate data for Kaibara, Tanba (1991−2020 normals, extremes 1978−present)
The area of Tamba was part of ancient Tanba Province, and corresponds almost exactly with ancient Hikami District. Numerous burial mounds from the Kofun period are located in the area. During the Sengoku period, the area was dominated by Akai Naomasa, nicknamed the "Red Demon of Tanba" from his stronghold at Kuroi Castle. The area was conquered by Akechi Mitsuhide under Oda Nobunaga, but Kuroi Castle did not fall until three years after Akai's death. Under the Tokugawa shogunate, Kaibara Domain was established for a cadet branch of the Oda clan. Following the Meiji restoration, the area became part of "Toyooka Prefecture" in 1871 before merging with Hyōgo Prefecture in 1876, and being organized into various villages and towns with the establishment of the modern municipalities system on April 1, 1889. The modern city of Tamba was established on November 1, 2004, from the merger of all six towns of the former Hikami District: Aogaki, Ichijima, Kaibara, Kasuga, Sannan, and Hikami.[citation needed] Tamba is a very small city with Hikami as the biggest of the six original towns.
