“Odaiba is simply awesome!”
In my opinion, Odaiba is the most fascinating place in entire Tokyo.
It is surrounded by water, you can enter it via the Rainbow-bridge and some impressive buildings are inside the island - everything is clean and orderly.
When I first came there, I thought: This must be the place where rich people live in Tokyo. And you have indeed a different feeling - a positive one though.
Just try it out and go there, it pays off!
