While visiting Osaka I took some pictures of Namba City shopping mall since it's shown in Hidamari Sketch x Honeycomb.

Inside Namba City is both a shopping mall and the Nankai Namba Train Station.
More of the building.

A part of Namba City is Namba Parks which is shown in the Key visual novel Rewrite. Might go back and get some more pictures if they show it in the upcoming anime adaptation.
