Japan won the bid for the 2020 Olympics, and now is planning to build a one of a kind stadium to accommodate such events. The gigantic sports arena will be built in Shinjuku, a ward of Tokyo. The stadium features seating for 80,000, adjustable seating sections, and a retractable roof-top. As of now, they have not released any numbers on what the estimated cost will be, but I’m sure it’s slightly more than what my wallet can carry. Make sure to check out the video presented by the guys at Zaha Hadid Architects, they made sure to design something like none other.
