Wonder of modern architecture
Fuji TV is an institution of Japanese television, and the building in Tokyo is a real wonder of modern architecture. There are only a few days a year when you can visit the offices and studios and climb to the top of the metal ball to enjoy the amazing views of Tokyo Bay and the Rainbow Bridge. I recommend going up at about five o'clock then waiting an hour to see how the landscape of the city is completely transformed as dark falls. It's not as high as the observation deck of the Tokyo Tower, but its located on the other side of the bay makes for some truly unique views. Admission is 500 yen, and you can drink in a bar there.
