I was a little bit surprized when I read this page and see that ET:QW has a Japan map:

Individually, as a Japanese (live in Yokohama, the location near Miura), the idea of that the Strogg take over a sewage facility in Miura Peninsula and are preparing for subterranean attack into the urban interior is awesome. I like both parts of the choice of the location and the situation (enemy uses the sewer network) which feel very realistic, and most of Japanese people should have the same positive feeling as how I felt.
If you want to add some reality into that map, you can feel free to ask me anything about Miura or any questions about Japan. Although both the choice of the location and the situation, or everything I can read or see right now look perfect to me!
