There are no material updates concerning when they are opening, the dates published are similar to previously noted during financial results reporting (but at least we know Space Mountain is calendar year 2027 meaning before 12/31 rather than fiscal year 2027 which runs to end of March 2028):
- Space Mountain Earthrise - TBD 2027
- Sugar Rush: Sweet Rescue - Spring 2027
Sugar Rush: Sweet Rescue
"This indoor attraction, themed after the Disney movie "Wreck-It Ralph," is an interactive game that can be enjoyed by children and adults alike.
To save the world of "Sugar Rush," a racing game set in a candy kingdom, which is in danger of being destroyed by a glitch created by King Candy, the "Sugar Bugs," guests enter the game world and join forces with familiar characters from the movie, such as Ralph and Vanellope.
Immerse yourself in the colorful game world and enjoy restoring the Sugar Bugs to their original cute candy forms, such as gummies and cupcakes."
Space Mountain Earthrise
"Space Mountain Earthrise is an all-new indoor roller coaster-type attraction that takes guests on an unforgettable journey through outer space, featuring brand new architecture and a newly developed ride system that combines imaginative storytelling and immersive theatrical effects inspired by the wonders of space.
From there, guests can enjoy a dynamic and immersive experience through the cosmos unlike ever before, with special light and sound effects inspired by various space phenomena. Additionally, in a first for roller coasters at Tokyo Disney Resort, the ride vehicles will come equipped with an onboard audio system. The attraction’s exterior incorporates curved features designed after the movements of celestial bodies and forms found in nature, such as trees and flowers — an expression of the connection between space and nature."
