This is so exciting! A Frozen theme land is coming to Tokyo DisneySea, opening sometime after the first half of 2017.
Look at that! Not only it's got Frozen ride, it has everything else as well. Arendelle (much likely to be a themed Meet-and-Greet area), the village and even Elsa's ice castle on the mountain top!
The land will be constructed in an area of the park which has yet to be developed.
As part of the 10-year development plan which the resort announced last year, the opening of the Frozen area will be accompanied by two new areas themed to Beauty and the Beast and Alice in Wonderland, at Tokyo Disneyland Park.
You can check out the official announcement here (in Japanese), as well as look at the concept art.
