Kawasaki's Warehouse arcade, near Yokohama, is a fantastically detailed, gritty recreation of the old walled city of Kowloon, near Hong Kong. The Tokyo Times photos depict a place that's like a fevered Gibson dream, and note that there's an accompanying, spooky soundscape. This is going on my must-see list for our next Japan trip.
