Odaiba (お台場) is a large artificial island in Tokyo Bay, Japan, across the Rainbow Bridge from central Tokyo. [Reference]
What to do in Odaiba?
I wanted to go there initially because of Ooedo-Onsen-Monogatari, but due to the personal concerns on Fukushima and onsen; with heavy rain where most of the tourists would also go there, I have decided to skip it. Instead below were visited on the island:
Rainbow Bridge
Odaiba Statue of Liberty
Transportation: Daiba Station (Yurikamome line), Exit 1.
