Tokyo DisneySea has a nautical exploration theme to it. There are seven themed areas Mediterranean Harbor, American Waterfront, Lost River Delta, Port Discovery, Mermaid Lagoon, Arabian Coast, and Mysterious Island. No surprise to say that all of the areas have incredible attention to detail, and spotlessly clean.
