Tokyo Disney Resort has released a couple of concept images for potential area redesigns at Tokyo Disneyland and Tokyo DisneySea. You can see them in my front-page post at https://www.themeparkinsider.com/flume/202504/10847/.
Caveat: Oriental Land has not committed to either of these projects, and its initial concept art does not always end up matching final products. So take this with a Mack Truck-sized block of salt.
But that should not stop the fun on looking through the concept art to play "guess the attraction." You can enlarge the images by right-clicking and loading them in a new tab.
What do you see?
I'm not going to try guessing Port Discovery because it all looks to generic to hone in on any potential theming.
As for Adventureland, it looks to me like Encanto on the left and potentially a mini Avatar land on the right.
The art is too vague to get any sense of IP. . . Encanto is a good guess, but I disagree with avatar for the Adventureland concept. The roller coaster on the left looks interesting, with it darting and out of the green rings through the mountain, but I don't really see what IP that could belong to. On the other image I see some architecture that reminds me of the monsters Inc Disney Hollywood studios concept art with the colors and shapes, but this is all hopeless speculation anyway.
I had briefly thought Up with balloons
Robert, you're the expert. I want to see your guesses. :)
