From Shimbashi station (trains depart every 5min), the Yurikamome ("black-headed seagull") line automated transit service transports you to Odaiba, all of the sites of which it calls at. After slaloming between the tower blocks and turning around on itself, the train reaches Rainbow Bridge, from where the views over Tokyo and Odaiba are superb. For a day's unlimited travel with the option to hop on and off, get a One Day Open Pass.
