History

The Aioi area was part of ancient Harima Province and was located on the San'yō highway linking western Japan with the Kinai region. The area was the location of a stronghold of the Ebina clan, originally from Sagami Province, who were retainers of the powerful Akamatsu clan. In the Edo period, the area became part of the holdings of Akō Domain. The village of Ō (相生村, Ōmura) was established with the creation of the modern municipalities system on April 1, 1889. It was raised to town status on January 1, 1913, becoming Ō (相生町, Ō-chō). The town merged with the neighboring town of Naba on April 1, 1939, and the reading of the kanji of its name was officially changed to "Aioi" on April 13, 1939. It was raised to city status on October 1, 1942. Aioi merged with the villages of Wakasano and Yano on April 1, 1954.
