Odaiba was a short trip my friends and I made during our last few hours in Tokyo because it was only a train ride away. This was actually my second time coming here because the first time was with my family during the summer. I realize that winter is their low season so there are not many people around and it is very quiet. Several stores and restaurants may be closed, especially the ones at the Decks Tokyo Beach (or at least when I went) but you can still go up on the deck to enjoy the view. Odaiba is a very colorful place at night because the ferris wheel, bridge, and attractions within stores light up. I suggest heading to Odaiba when the weather is warmer because other than it being more lively and more stores open, they also have more events such as the Tokyo Bay Grand Fireworks Festival in August. During the festival, many young couples and friends would have picnics by the river and watch for the fireworks display. My friends and I stayed for dinner with the view of the river and Rainbow Bridge. Everything is mostly walking distance from each other so there is no need to public transportation once you're in the area.
