Odaiba (お台場) is an artificial island connected to the city via Rainbow bridge – a bridge that is lit up at night in the colors of a rainbow (duh). Its offers are centered around entertainment: Gundam statue, ferris wheel, museums, parks and gaming centers are all located here.
Harajuku (原宿) is just a short walk away from central Shibuya, it features shopping streets (just like almost every other district in Tokyo) but also the heart of Japanese subculture and street fashion. To escape the crowds, enter Tokyu Plaza and enjoy the beautiful rooftop terrace overlooking lively Harajuku.
