You can see a bit of the Walled City in the old Van Damme movie, Blood Sport [1].

There used to be an incredible multi-story arcade outside Tokyo, あなたのウェアハウス [2], with two of the floors being themed as KWC. The weathering on all the elements (including the escalator and crane games!) was fantastic.
