Rainbow Bridge is very similar in structure to the Golden Gate in San Francisco. You can get to Odaiba Island by car, train or monorail from the city of Tokyo. The most impressive thing for me is to see it at night. Everything is lit up around you and the thousands of colourful barges that can be rented for parties fill up the Sumida river. If you go to any of the restaurants in Odaiba overlooking the bay is simply magical.
