Osaka Castle Park Office

The Naejangnae Hilso is a park management office inside Osaka Castle Park, on the site of a prewar Osaka Army arsenal. A gate pillar and a red brick wall remain at the entrance, showing traces of the prewar period. During the war the western garden held many arsenal warehouses, and today all the buildings except the division headquarters have been demolished. The surroundings are a mix of things, so the area feels less orderly.
