Hey, this was a cool find, thanks for sharing these.

Egypt: https://www.nicovideo.jp/watch/sm23854453

According to Google translated comments from the comments on his Niconico: "Some songs from Egypt, and Chinese and Japanese stages are not my responsibility."

So this would at least confirm the China and Japan themes are Takaro Nozaki's.
