The area of Kaita was part of the ancient
Aki Province. In the
Edo Period, it was part of the holdings of
Hiroshima Domain. People started living in this area during the
Jomon period, and the coastline was further inland than it is today. The place name 'Kaita' first appeared in records around the end of the
Heian period, when there was a
shōen manor owned by the
imperial family called 'Kaita-sō' which existed into the
Nanboku-chō period. A market town called 'Kaitaichi' developed around the mouth of the Seno River and became a
post station on the
Sanyōdō highway which connected
Kyushu with the
Kinai region. Following the
Meiji restoration, the town of Kaitaichi and the village of Okukaita were established within
Aki District, Hiroshima with the creation of the modern municipalities system on April 1, 1889. The two municipalities were merged on September 30, 1956, to form the town of Kaita. ==Government==
