Rainbow Bridge レインボーブリッジ(東京港連絡橋)
1.7 km on foot above the bay: 20–30 minutes each way, free, no cars.
The bridge, officially named Tōkyō-kō Renrakukyō, opened on 26 August 1993 after work begun in 1987 by Kawasaki Heavy Industries: it links Shibaura to Odaiba over Tokyo Bay with a 798-metre double-deck structure that carries the motorway, the Yurikamome line and the pedestrian walkway together. The English name, chosen by public vote, is the one that stuck; the official Japanese name never entered everyday language.
