An ultra-futuristic party zone in Tokyo; you can get there via a special train (if you ride in front, it's like a roller coaster) or by riverboat from Asakusa. It houses a beach (inlet from the ocean), a tv station, multiple shopping centers/movie theaters, a monstrous game center, a huge ferris wheel, an amusement park, and a Toyota factory/showroom.
In the daytime:
the Rainbow Bridge and boats
I like to sit on the beach and watch the sunset:
The ferris wheel at night.
And just in case you're lonely for the US...
The statue of Liberty.
