Kawasaki’s industrial zone, built on man-made islands reclaimed from Tokyo bay is actually surprisingly photogenic and quite an interesting place to spend an afternoon in. I went there on an outing with the Tokyo Cameras photo club and really enjoyed it. From Shinagawa station in Tokyo, take the JR Keihin Tohoku to Tsurumi Station. Change to the Tsurumi Line and get off at Ogimachi or Ookawa Station. It takes about 40 minutes, and costs 290 yen (be careful, because the Tsurumi Line runs infrequently, especially on weekends).
