There is so much to see and do in Odaiba, you can easily spend several days while shopping, visiting museums, Fuji TV, the giant Gundam, the cinema, Sega Joypolis, Gundam Cafe and more. The Rainbow Bridge is one of Odaiba’s iconic sights and is especially beautiful in the evening, when looking from the decks or beach.
Fuji TV is one of Japan’s private, nationwide TV stations. There are all kind of exhibits of popular television programs and you can visit the observatory deck which gives you an amazing panoramic view of Odaiba. You can also buy Fuji TV goodies and make photos with the Fuji TV Mascot. Except for Monday, Fuji TV is opened daily from 10:00 to 18:00. Free entry, although the observation deck is 550 yen. Things tend to get crowded in the weekends, so if you prefer some more breathing space, go weekdays.
