It wasn’t until 1997 that the name Disney Sea and its general plans were made public. Finally in 2001 after spending over 3 billion US dollars to build, Disney sea was born.

Mediterranean Harbor is the entrance “port-of-call” and themed as an Italian port city, with Venetian Gondolas that guests can board and ride.[1] Mediterranean Harbor’s layout differs from the entry “lands” of other Disney parks as it is a large “V” shape rather than a main street that leads to a central hub as seen on Main street USA at disneyland.
Built into the architecture of the port is Tokyo DisneySea Hotel MiraCosta;
Mermaid Lagoon is home to the characters of The Little Mermaid. The facade is made to resemble King Triton’s palace and features seashell-inspired architecture. This “port of call” is mostly indoors and recreates the feeling of being underwater.

Lost River Delta is Located at the back of the park, the dominant structure in this “port of call” is the ruins of an ancient Aztec pyramid which houses the dark thrill ride, Indiana Jones Adventure: Temple of the Crystal Skull. Also in the Lost River Delta is the DisneySea Steamer Line which transports guests back to Mediterranean Harbor, The Lost River Delta contains a roller coaster named Raging Spirits, which opened in 2005 and is similar to Indiana Jones et le Temple du Péril at Disneyland Park in Paris.
Port Discovery: This “port of call” is home to the fictional ‘Marine Life Institute’; Port Discovery houses two attractions: Aquatopia, a boat ride that uses (the ‘trackless’ technology also used in Tokyo Disneyland’s Pooh’s Hunny Hunt and Mystic Manor at Hong Kong Disneyland) to move and spin through a lagoon amid waterfalls and whirlpools, and the DisneySea Electric Railway, an overhead electric trolley that transports riders to and from the American Waterfront.

American Waterfront represents the northeastern seaboard of the United States in the early 20th century. It features two themed areas, an “Old Cape Cod” section, and a “New York Harbor” section. The land is dominated by a large passenger ship, SS Columbia, which is usually the site for various shows and events. Guests have the option of riding the area’s “Big City Vehicles” which roam the streets of the area. It also features the 2 ft 6 in (762 mm) gauge DisneySea Electric Railway. The port has a Broadway-themed theater which plays the show “Big Band Beat”, which features 1940s-style swing jazz performed by a 12-piece band, as well as 20 singers/dancers.[1] Unfortunately, we didn’t get a chance to see this show on this trip. The port’s most popular attraction is the Tower of Terror which used to also be at California Adventure.
Announced in June 2018 shortly before we visited, an eighth “port of call” named Fantasy Springs will be added to the park as part of its largest expansion so far. It will comprise three areas themed to the films of Frozen, Tangled, and Peter Pan. There will be a total of four new attractions, three restaurants, and a new luxury hotel situated in the park itself.[27] The entire area will be connected to the existing park through a pathway between the ports of Lost River Delta and Arabian Coast.[28] its opening date has been pushed back to 2023.Aquatopiais the second of only five attractions in the world to use a trackless ride system designed by Walt Disney Imagineering. The water in the lagoon is about 5 cm (2 inches) deep, as the vehicles actually roll along the shallow floor on wheels. The water is kept moving to create the illusion of depth, and occasional funnel drains give the appearance of foreboding whirlpools.
When Tokyo Disneyland was constructed, local railway laws were applicable to any railway that connected two points and can be used as a means of transportation, even if the railway was entirely on private land.

Created for Tokyo DisneySea and first being named in the Fortress Explorations walkthrough attraction, society of explorers and adventurers. was inspired by the defunct Pleasure Island’s Adventurers Club at Walt Disney World.
Fortress Explorations is the original Society of explorers and adventurers attraction. It lays the foundations of what Society of explorers and adventurers is which future Imagineers pick up on and expanded. You can now find references to society of explorers and adventurers throughout most of the Disney parks around the world now. It all started here though. It introduces us to the 4 core concepts of the society of explorers and adventures. Adventure, Romance, Discovery and Innovation. Here you can climb aboard and explore the ship ostensibly used by the original society and adventurers. Would this exhibit work in the United States? or would there be leftist outrage for its underhanded glorification of imperialism?
