Mediterranean Harbor is the entrance or "port-of-call" for Tokyo DisneySea, it is modeled after the fictional Italian port city Porto Paradiso. It is the location for the Venetian gondolas that guests can board and ride.
Mediterranean Harbor is different than Disney's other park entry hubs as it is shaped as a V rather than having a main street leading to the hub. Here you can find attractions such as Fortress Explorations, The Legend of Mythica, Fantasmic!, a nighttime show set with special barges, fountains, pyro effects, Disney characters and fireworks.
