Tokyo DisneySea is divided into seven themed ports. The seven ports have different themes related to Disney movies or originally created by Disney. Six ports are laid out roughly around the center, and the center area is one of the ports which is called Mysterious Island. Instead of Cinderella Castle that is the icon of most Disney parks, there is Mount Prometheus on the center of Mysterious Island which is the icon of Tokyo DisneySea. In the entrance plaza, there is a huge model of the earth with a water fountain. It is called the DisneySea AquaSphere and it is the symbol of Tokyo DisneySea.
