Odaiba is a popular shopping and entertainment district on a man made island in Tokyo Bay. It originated as a set of small man made fort islands (daiba literally means "fort"), which were built towards the end of the Edo Period (1603-1868) to protect Tokyo against possible attacks from the sea and specifically in response to the gunboat diplomacy of Commodore Perry. More than a century later, the small islands were joined into larger islands by massive landfills, and Tokyo began a spectacular development project aimed to turn the islands into a futuristic residential and business district during the extravagant 1980s. But development was critically slowed after the burst of the "bubble economy" in the early 1990s, leaving Odaiba nearly vacant. It was not until the second half of the 1990s, when several hotels, shopping malls and the Yurikamome elevated train line were opened, that Odaiba developed into one of Tokyo's most popular tourist attractions and date spots with a wide selection of shopping, dining and leisure options.
Despite the initial setbacks, several lavish development projects did materialize, including some of Tokyo's boldest architectural creations, such as the Fuji TV Building, Telecom Center and Tokyo Big Sight. Modern city planning furthermore provides Odaiba with plenty of green space and a pleasant division of motorized and pedestrian traffic using elevated walkways and the like.
