The port of Onomichi opened in 1168, serving for the next five centuries as a significant rice shipment center and a hub for foreign trade. While its commercial importance shifted during the Edo period, it remained a vital maritime location. On April 1, 1898, Onomichi Town in Mitsugi District was officially incorporated as the second city in Hiroshima Prefecture.
The city expanded significantly through the 20th century. In 1935, the notable ocean liner RMS Adriatic was scrapped at the city's docks. Between 1937 and 1970, Onomichi incorporated numerous neighboring municipalities, including the town of Kurihara and the village of Yoshiwa (1937), Sanba (1939), Fukada (1951), and several other villages from Mitsugi and Numakuma Districts through the 1950s. The town of Mukaihigashi joined the city in 1970.
In the 21st century, the city's boundaries reached their current form through major mergers. The towns of Mitsugi and Mukaishima were merged into Onomichi on March 28, 2005, followed by the incorporation of Innoshima and Setoda on January 10, 2006.

Onomichi has a mayor-council form of government with a directly elected mayor and a unicameral city council of 26 members. Onomichi contributes three members to the Hiroshima Prefectural Assembly. In terms of national politics, Onomichi is part of the Hiroshima 5th district of the lower house of the Diet of Japan. Prior to 2022, part of the city was in Hiroshima 6th district.
The Kyodo-kai yakuza syndicate is based in Onomichi. The Kyodo-kai is the second largest yakuza group in the Chugoku region after the Hiroshima-based Kyosei-kai.
Onomichi has prospered as a port town and a commercial city. Before World War II, it had an economy comparable to that of Hiroshima City. Shipyards have existed in Onomichi, Mukaishima, and Innoshima for a long time due to their location, which is blessed with water transport. In recent years, the shipbuilding industry has been in decline.
