There is a huge "panoramic device" on the Bay of Tokyo.
Rainbow Bridge spanned between
Shibaura and
Odaiba over the bay, commands a super view of the whole Tokyo Port.
As two highways and the new transit "Yurikamome Line" run on the bridge of two stories, you can enjoy seeing the great scenery through a car or train window.
However, I recommend you to cross the bridge walking on the promenade.
You have the super-panoramic view to yourself here.
It is a half-hour walk with enjoying a sea breeze to the other side of the bridge, 1.7 km in distance.
