Location and the Integration of Neighboring Ports
Ushimado Port lies in the former town of Ushimado, now part of Setouchi City, on the eastern side of Okayama Prefecture. Historically, Kashinokuri Port was located nearby to the west. Following the consolidation of local ports, the former Ushimado Port became the Ushimado District, while the former Kashinokuri Port became the Kashinokuri District. Both are now administered as parts of the same port.
A Harbor with a Rich Maritime History
Ushimado Port has long been known as an important harbor on the Seto Inland Sea and has also been called Karako no Seto. During the Edo period (1603–1868), the Okayama domain developed facilities including a lookout post for monitoring foreign ships and a tall lighthouse. The port welcomed diplomatic missions from Korea, known as the Joseon Tongsinsa, as well as processions of feudal lords traveling under the alternate-attendance system.
These activities gave Ushimado an important role in maritime transportation and international exchange. The historic character of the harbor reflects the Seto Inland Sea’s former importance as a major route for trade, travel, and diplomacy.
During the Meiji period (1868–1912), Ushimado became one of Okayama Prefecture’s principal ports. However, its prominence gradually declined after the development of railways shifted transportation patterns inland. Several plans to build light railways failed to materialize, although land reclamation and development took place in the early Showa period. Facilities such as a fisheries research station and a government monopoly bureau warehouse were established during this time.
During Japan’s postwar period of rapid economic growth, port infrastructure was modernized with the construction of a prefectural pier and cargo landing facilities. As commercial port activity later decreased, the harbor increasingly came to serve as a transport hub for nearby islands and a base for fishing and recreational boating.
The History of Kashinokuri Port
Kashinokuri Port, now part of the same port area, has a history closely linked to salt production. During the Tenpo era (1830–1844) of the Edo period, reclaimed land was developed into salt fields. Salt produced there was shipped out through Kashinokuri Port.
As industrialization progressed, traditional salt production declined. Today, some of the waterways that once carried seawater into the salt fields remain in use as sheltered moorings for boats, preserving traces of the area’s former coastal industries.

According to statistics for fiscal 2015, Ushimado Port recorded 46 vessel movements, representing a combined gross tonnage of 18,841 tons.

The crossing takes approximately five minutes. Ferries generally operate every 40 minutes during the daytime, while services in the early morning and evening run at intervals of approximately 30 to 60 minutes.
