The Role of Osaka Port as Part of Hanshin Port
Osaka Port forms part of Hanshin Port together with Kobe Port, Amagasaki-Nishinomiya-Ashiya Port, and Sakai-Semboku Port. Under Japan’s Port Regulations Law, it is designated as a Specified Port.
Osaka Prefecture has also designated the port as a Marine Transportation Base, giving it an important role as a disaster-prevention and emergency transportation hub.
Location and Port Area
Osaka Port is located at the innermost part of Osaka Bay. Amagasaki-Nishinomiya-Ashiya Port lies to the north, while Sakai-Semboku Port is located to the south.
The northern end of the port area is the Nakajima River on the border with Amagasaki City in Hyogo Prefecture, while the southern end reaches the Yamato River on the border with Sakai City.
The principal waterfront districts are concentrated south of the Yodo River, including Konohana, Minato, Taisho, Suminoe, and Nishi wards. These areas contain many of the port’s major facilities and logistics functions.
Characteristics and Development of Osaka Port
Unlike Kobe Port, which was developed as a national government project, Osaka Port has a long tradition as a municipally operated port constructed and managed by Osaka City itself.
Following the Great Hanshin-Awaji Earthquake of 1995, the port became increasingly important as an international container hub. In 2022, its handling volume of foreign-trade containers reached approximately 2.13 million TEUs, making it the fifth-largest port in Japan by this measure.
Port Statistics for 2022
According to official Osaka City statistics, Osaka Port recorded the following figures in 2022.
Vessels entering the port: 21,267 vessels, with a total gross tonnage of 101,004,174 tons
Ocean-going vessels: 4,494 vessels, with a total gross tonnage of 60,761,644 tons
Coastal vessels: 16,773 vessels, with a total gross tonnage of 40,242,530 tons
Total cargo handled: approximately 85.57 million tons
Breakdown of Imports and Exports
Exports: 8.49 million tons, including 7.65 million tons of containerized cargo
Imports: 25.87 million tons, including 24.72 million tons of containerized cargo
History of Osaka Port
From a River Port to a Modern Seaport
The history of Osaka’s port dates back to ancient times, including Naniwazu and Suminoe-no-tsu around the 6th century. During the Heian period, the area functioned as a river port known as Watanabeno-tsu.
However, the accumulation of sediment in the Yodo River gradually reduced its importance. During the Edo period, Osaka became known as the “Kitchen of Japan” as water transportation flourished and the city developed into a major economic center.
At that time, however, Osaka was not yet a modern seaport. Goods were primarily transported through rivers and inland waterways.
Development of the Ajigawa and Kizugawa Waterways
In 1683, the engineer Kawamura Zuiken oversaw the excavation of the Ajigawa River to improve flood control and navigation on the Yodo River system.
The Kizugawa River was subsequently excavated in 1699. These projects established important waterways connecting Osaka Bay with the urban center.
In 1704, the Yamato River was also diverted, creating a new course toward Osaka Bay and further improving the region’s waterways.
The Opening of Osaka Port and Its Impact
Osaka Port officially opened in 1868. At first, however, its facilities were inadequate to serve as a major port of call for foreign ships, and many foreign merchants moved their activities to Kobe.
As a result, Osaka temporarily lost its position as an international trading center. Continued flood-control projects and port improvements gradually restored the port’s importance.
The First Reconstruction Project and Construction of the Modern Port
In 1873, Dutch engineers G.A. Escher and Johannis de Rijke came to Japan to work on flood control and port development in Osaka.
They proposed constructing a flood diversion channel for the Yodo River and developing a new port. However, financial difficulties prevented these plans from being realized at that time.
After the major flood of 1885, improvements to the Yodo River were given priority. In 1890, a survey for port construction around Tempozan began under citizen-led initiatives.
In 1897, construction of the port at Tempozan officially began as an Osaka City project. The ambitious undertaking required an investment of more than 20 times the city’s annual budget.
This major project marked the beginning of Osaka Port’s development as a full-scale modern seaport.
Osaka Port Today
Osaka Port has undergone numerous changes and periods of development throughout its long history. While retaining its tradition as a municipally operated port, it has grown into an important hub for international maritime trade.
Today, with cooperation between Osaka City and Osaka Prefecture, the port continues to play a significant role in regional economic development, international logistics, and disaster preparedness.
For travelers, Osaka Port also provides a gateway to the city’s waterfront attractions, including the Tempozan area and other destinations along Osaka Bay, where the history of maritime trade meets modern urban tourism.
