Report National Stadium(1964 Olympic Stadium) in Tokyo 2020 Summer Games Posted May 24, 2015 I found and article clearing up some of the statements trhown out recently about the stadium. Here are the facts: ( http://number.bunshun.jp/articles/-/823372 ) 1. The retractable roof will be constructed after the games due to both budget and time constraints. 2. The stationary roof (obviously) will be built as planned. 3. The retractable seating feature will not be constructed. Therefore, the stadium will be in track mode permanently (like Nissan) 4. Not 30,000 seats, but just 15,000 seats will be temporary. Therefore the final capacity will be 65,000 which is plenty for a national stadium.
