In Japan there two Disney parks – Disney Land and Disney Sea. Although the name has Tokyo, it’s actually in Chiba.
Disney Land is older: it opened in 1983. It has a castle of Cinderella, Splash Maintain, Big thunder Maintain, and so on which is similar to Magic Kingdom in FL.
Disney Sea opened in 2001. Its concept is “sea” and is a first concept of Disney in the world. As one of characteristics of Disney Sea, many restaurants have alcohol.
Some people come for one park or stay two days and go to both parks. But some people go to both in one day! That sounds hard, doesn’t it?!
