Last year, Nintendo and Universal Studios began collaborating on a Nintendo addition to Universal theme parks. According to Sankei News (via Kotaku), the first details of this project emerged last week, including the cost, how large the area, what park it will be in, and when the project will be done.
The new additions will come to Universal Studios Japan at the cost of $351 million dollars. If you want an idea of how big the addition will be, check out the figure below:
