Tokyo Disney Resort’s massive transformation of Tomorrowland is moving full speed ahead, and new construction updates are giving fans another glimpse at what could become one of the most expensive attraction projects in Disney history.
For more than 40 years, Space Mountain stood as one of the defining experiences at Tokyo Disneyland. That chapter came to an end in 2024 when the beloved indoor coaster permanently closed, clearing the way for a completely new version scheduled to open in 2027. Rather than refurbishing the existing attraction, Tokyo Disney Resort has chosen to start over from scratch, creating an entirely new experience that will serve as the centerpiece of a reimagined Tomorrowland.
The history of Space Mountain stretches back decades. The attraction first debuted at Walt Disney World’s Magic Kingdom in 1975 before arriving at Disneyland Park in California in 1977. Over the years, versions of the coaster have appeared around the world, becoming one of Disney’s most recognizable attractions. Tokyo Disneyland’s Space Mountain opened with the park itself in 1983, making it one of the resort’s original rides and a fixture of the skyline for generations of guests.
While other Disney destinations have updated their versions of Space Mountain through overlays and rethemed experiences—including Hyperspace Mountain at Disneyland Paris and Hong Kong Disneyland—Tokyo’s project goes far beyond a simple upgrade.
The attraction welcomed its final riders on July 31, 2024. Construction walls quickly surrounded the area afterward, and demolition crews began removing the familiar mountain structure. For many Disney fans, seeing the iconic peaks disappear marked a major milestone in the resort’s history.
The replacement attraction sits at the heart of a much larger Tomorrowland redevelopment led by Tokyo Disney Resort and its operator, Oriental Land Company. Alongside the new coaster, guests will also find a redesigned plaza intended to create a more immersive futuristic setting around the attraction.
The scale of the investment continues to draw attention. According to official documentation released by Oriental Land Company, the project carries an estimated cost of approximately ¥70.5 billion, or about $461 million USD. That places the development among the most significant attraction investments ever undertaken at a Disney park.
Although many fans have embraced the unofficial nickname “Space Mountain Earthrise,” Disney has not announced a formal title. Current project materials continue to identify the attraction simply as “Space Mountain (2027).”
A recent construction video shared by X user @tacchi0712 has provided one of the clearest looks yet at the ongoing work. The footage appears to show major structural progress taking place behind the construction barriers, along with what looks to be new lighting elements already being tested as the future attraction begins to take shape.

The project also aligns with Tokyo Disney Resort’s broader strategy of investing heavily in large-scale expansions. The resort recently opened Fantasy Springs at Tokyo DisneySea, one of the most ambitious additions in its history, and the new Space Mountain appears poised to play a similarly important role for Tokyo Disneyland.
Disney’s previously released concept artwork hints at a dramatically different mountain than the one guests knew for decades. The design features a sleek exterior illuminated with glowing lighting effects and futuristic architecture. The new attraction is expected to combine updated ride technology, immersive storytelling, and modern visual effects as part of a reimagined Tomorrowland experience.
For now, guests can only follow the project’s progress from beyond the construction walls. With a 2027 opening date still on the calendar and work visibly advancing across the site, Tokyo Disney Resort’s next version of Space Mountain is steadily moving closer to launch.
