Location and Geography
Nishiyodogawa Ward is located in the northwestern part of Osaka City and has convenient access to the Umeda area in southeastern Osaka.
The Nakajima Industrial Park occupies part of the western area, while residential neighborhoods have developed alongside industrial facilities. As redevelopment has progressed, the character of the district has gradually changed.
A History Shaped by Rivers, Industry, and Urban Development
From River Islands to a Modern Urban District
The land that now forms Nishiyodogawa was created over time by sediment carried by the Yodo River. In ancient times, the area consisted of numerous islands collectively known as Naniwa no Yasoshima, or the “Eighty Islands of Naniwa.” Place names such as Mifunejima and Himejima remain as reminders of this landscape.
In ancient times, parts of the area were associated with the territories of Sumiyoshi Taisha. Fishing flourished during the medieval period, while agriculture developed alongside fishing as land reclamation and new-field development progressed during the Edo period.
Industrialization and Its Transformation
From the Meiji era onward, factories began moving into the area, and Nishiyodogawa developed into a major heavy industrial district during the early Showa era.
However, serious pollution problems emerged from the 1950s onward. From the 1970s, many factories subsequently withdrew from the area, leaving large sites that were gradually redeveloped for housing and other urban uses.
The Development of Nishiyodogawa Ward
Nishiyodogawa Ward was established in 1925 as part of Osaka City’s expansion. At the time, alternative names such as “Shimoyodo Ward” and “Himejima Ward” had been proposed, but the name Nishiyodogawa was ultimately adopted.
Administrative boundaries were reorganized in 1943, including the transfer of areas south of the Yodo River to other wards. This resulted in the basic shape of Nishiyodogawa Ward seen today.
War, Pollution, and Community Recovery
Damage from the Osaka Air Raids
During the Pacific War, the Osaka air raids of 1945 destroyed the ward office and public health center. As part of postwar reconstruction, the first Nishiyodogawa Ward Office building was completed in 1947.
The Pollution Crisis
After the war, however, industrial pollution became a serious problem. Until the 1970s, residents suffered from health problems associated with air pollution, including chronic bronchitis and asthma.
In 1970, relief measures for people affected by industrial pollution began under the Special Measures Law Concerning Relief for Pollution-Related Health Damage. At the time, more than 1,000 people out of a population of approximately 110,000 in Nishiyodogawa were officially recognized as suffering from pollution-related illnesses, a proportion that was high compared with other areas of Japan.
