The other day we took a little trip to Odaiba, an island in the harbor made of trash. It sounds like it would be junky, but it has become a very ritzy sort of area. There are also some decent views back toward Tokyo. We ate a picnic lunch on the beach, then walked around to see some of the shopping centers, the giant ferris wheel (second largest in the world) and the Toyota showroom.

Crazy Japanese building... and a mini statue of liberty to the left
The giant ferris wheel... second only to the London Eye. The lowest gondola on the bottom right is all glass.
