Odaiba is a popular waterfront area close to central Tokyo connected by the Rainbow Bridge. The area is a popular area for any sort of outdoor gathering among tourists and locals alike. Odaiba is a short train ride away from Shimbashi or Shinjuku on the Yurikamome line or the JR Saikyo line respectively. This area is known for the recently moved Tsukiji Fish Market (now, Toyosu Fish Market), shopping centers, parks, and entertainment facilities. 
When you get tired of wandering around the waterfront, or simply feel like it’s time for a meal, rest assured that this area has a variety of eateries to choose from
