Once just a pipe dream of Nintendo fans everywhere, a Nintendo theme park land will soon be real. Super Nintendo World is a huge upcoming expansion to Universal Studios Japan, costing over $351 million (with some reporting the sum to be as much as $544 million). Much like the Wizarding World of Harry Potter was to Universal Studios Orlando and Hollywood, Super Nintendo World will be an additional land, rather than an entire stand-alone theme park.

Since the expansion was announced in 2015, information on the has gradually trickled in. We’ve collected all the details about Super Nintendo World into one handy-dandy FAQ. As we learn more info, we’ll update the post.

Here’s everything we know so far about the upcoming Super Nintendo World:

Wait — there’s a Super Nintendo World in the works?

Sure is!

Oh boy! Where will it open?

The first version of Super Nintendo World will open in Universal Studios Japan in Osaka.

When is the Osaka expansion opening?

First announced in 2015, Super Nintendo World is set for completion in time for the 2020 Summer Olympics in Tokyo. In 2017, Universal Studios Japan held a groundbreaking ceremony in Osaka to mark the beginning of construction. Featuring a dancing Mario, the ceremony provided a small sneak peak of the style and tone of the expansion.

What exactly is going to be in the land?

So far, it looks like the land will be mostly Mario-themed, at least initially. From the concept artwork and commercial rendering, we can theorize that both Peach’s castle and Bowser’s castle will be central to the design. There will likely be lots of atmospheric elements, such as Piranha Plants and question mark blocks. Character meet-and-greets with the various Mario characters, as well as restaurants and retail locations will populate the land.

Universal Studios hasn’t revealed any commercial renderings or publicity info about whether any other Nintendo properties outside Mario will be included, but with such a vast collection of beloved franchises to choose form, it is possible other Nintendo characters and games could eventually make appearances.

Images of a model rumored to be an early design of the park may reveal more of the layout. Posted by the Unofficial Universal Orlando Podcast, the images date back to 2016, so it is likely that even if the model is real, the plans have changed since its creation. The model includes a Toadstool cafe, a looming Bowser’s castle, and a Mario Kart attraction. Additionally, the images feature a separate Donkey Kong area, which appears to have a minecart-themed ride.

What will the rides look like?

Theme park reporters, critics, and fans have speculated for a couple years about what rides will appear in Super Nintendo World. The most persistent rumor has been a Mario Kart attraction, due to Universal’s International Association of Amusement Parks and Attractions 2018 convention demo: a ride that looks and acts like a dark ride, but uses coaster technology.

Any chance it’s going to open stateside?

Yup. Universal plans to expand the Nintendo land to Universal Studios Hollywood and Universal Studios Orlando. But Universal Studios hasn’t publicly announced a timeline for the additional Super Mario World expansions. Stay tuned for updates.
