My plan was to take to Water Taxi from Odaiba Seaside Park to Hinode Pier and from there head to Shiba Park at the foot of Tokyo Tower, but to my surprise the first ferry was scheduled to leave at 11:30am, another two and a half hours in the future. This left me with two choices, cycle a big circle back over the Harumi Dori route and loop back to Tokyo Tower, or to walk Rainbow Bridge with my bicycle.
I found the entrance with no trouble and began walking my bicycle up a ramp towards what appeared to be a toll booth. Walking the bridge is free and you are indeed allowed to push your bicycle across, but in order to prevent you from riding the guys in the booth attach what can only be described as a "roller skate" to your rear wheel.
With my roller skate attached I set off over the bridge via the north walkway which gave spectacular views of both Tokyo Tower and Tokyo Sky Tree no to mention the Tokyo skyline itself and back over the island of Tokyo Bay where work has already begun on the venues for the 2020 Olympics.
Walking Rainbow Bridge certainly is a unique experience and while you can't cycle it I certainly recommend the route for cyclists looking for another way off the islands of Tokyo by. I'm really glad I walked the bridge and will never took at Rainbow Bridge in quite the same way again.
Rainbow Bridge is open to pedestrians from 9am until 9pm in the summer and 10am to 6pm in the winter. Access to the walkway is closed 30 minutes before closing time.
