Overview
The Nishiawaji Anti-Aircraft Gun Position was an air-defense installation constructed by the former Japanese military in the Nishiawaji area of Higashiyodogawa Ward during the 1940s. It consisted of six anti-aircraft gun emplacements arranged in a fan-shaped formation, together with a command post that controlled the position.
When it was first constructed, the installation was known as the Kuniji Anti-Aircraft Gun Position. Its primary role was to defend Osaka City against aerial attacks.
Location and Structure
The six gun emplacements were arranged in an arc, with a two-story command post at the center. Both the gun positions and command post were constructed using reinforced concrete (RC), providing a robust structure designed to withstand wartime air raids.
History of the Nishiawaji Anti-Aircraft Gun Position
Construction and Wartime Operation
1942: Four anti-aircraft guns were installed, establishing the basic defense position.
1944: Construction of elevated gun platforms began as part of efforts to strengthen the site’s air-defense capabilities.
June 1945: Six reinforced-concrete gun emplacements and a two-story command post were completed, and the position began full-scale operations.
The site was occupied by the 1st Company of the 1st Battalion, 122nd Regiment, 3rd Anti-Aircraft Artillery Division, 15th Area Army. Approximately 150 to 200 personnel were stationed there and are said to have been responsible primarily for defending Osaka City against air raids.
Postwar Reuse and Demolition
After the end of World War II, parts of the former military position were converted into residential areas and factories. One example was the No. 6 gun emplacement at the western end of the site. Its first-floor walls were removed, and the structure was reused as an ironworks facility.
Over the following decades, however, the remaining structures were gradually demolished.
1989: The No. 1 and No. 2 gun emplacements on the eastern side were demolished.
2012: The No. 4 and No. 5 gun emplacements were demolished.
February 2019: The No. 6 gun emplacement was demolished.
November 2019: The No. 3 gun emplacement was demolished.
May 2024: The last remaining structure, the command post, was demolished. With its removal, all of the former gun emplacements and the command post disappeared.

A Site That Tells the Story of War and Peace
The Nishiawaji Anti-Aircraft Gun Emplacement Ruins have undergone major changes since the end of the war. Parts of the former military installation were reused as homes and industrial facilities, while the remaining structures were gradually dismantled over the decades.
With the demolition of the command post in May 2024, the physical structures of the former position have disappeared, making it difficult to trace the site as it once existed.
Nevertheless, the history of Nishiawaji’s anti-aircraft gun position remains significant as a reminder of the wartime history of Osaka. When visiting Higashiyodogawa Ward or other parts of Osaka, learning about this former military site offers an opportunity to reflect on the history of war, peace, and the transformation of the city over time.
