Industrial and Port Area of Kawasaki
It is not at all a real tour destination, but for an introspective appreciation of where creature comforts such as Conditioning Shampoos, Hydrogenated Margarines, and Commercial Vehicles are created and shipped, this is the place.
There is a nice cool breeze from being so near the ocean, and Haneda Airport Runways are just a stone's throw across the river (but can't be accessed directly from here.)
Get there from East Side Kawasaki Station Bus Station #9, the Ukishima Bus Terminal-bound bus #3 and get off at "Ukishima Bus Terminal" Bus Stop.
