Sometimes a bridge isn't just for getting you from one place to another. The Rainbow Bridge, which links the mainland to the artificial islet of Odaiba, is also a tourist attraction in its own right at night. Built in the 1990s, the span has enabled this part of Tokyo Bay to flourish, and is surrounded by top tourist attractions.
The bridge is accessible on foot from subway stops or by taxi.
The nearest subway stops are Odaiba-Kaihinkoen Station and Shibaura-Futo Station.
The supporting towers of the bridge have been painted white, but they are lit up at night in rainbow colors, giving the bridge its nickname—its officially known as the Tokyo Bay Connector Bridge. The colored lights are charged up during the day by solar panels.
Crossing northern Tokyo Bay from the Odaiba waterfront entertainment district to Shibaura Pier, the Rainbow Bridge accommodates both vehicles and pedestrians. You can't enter the walkaway at night, however, and while you can push a bicycle across you can't ride it over the bridge.
It takes around twenty to thirty minutes to cross the bridge on foot, although most visitors linger at the benches in the middle and enjoy the view. There are pedestrian walkways on either side of the bridge, so pick the side with the view you most want to see. The view of Odaiba Seaside Park is the most popular.
