Odaiba

Odaiba is a large artificial island in Tokyo Bay. It is the home of the most of the Chosen Children, except T.K in Adventure and Ken Ichijouji in Zero Two. It is the location of the Fuji TV building, the workplace of Matt and T.K's father (incidentally, in our world, Fuji TV is the channel where the first 5 Digimon series is aired). Many important fights took place in Odaiba, like the battle against Parrotmon 4 years before the start of Adventure, the fight against Myotismon at the top of the Fuji TV building, the battle against VenomMyotismon near Tokyo Bay, and the battle against Armagemon at the Rainbow Bridge.
