Toyo Ito and Kengo Kuma compete for Tokyo Olympics stadium replacing Hadid
Two top Japanese architects are going head to head with designs for the 2020 Tokyo Olympic Stadium.
Kengo Kuma and Toyo Ito have unveiled rival proposals to build the sports arena, replacing Zaha Hadid’s competition-winning design.
The Japan Sport Council (JSC) has revealed images of the two designs competing for the Tokyo National Stadium contract.
The two schemes were submitted anonymously to a new competition for the 2020 Tokyo Olympic and Paralympic Games stadium – but according to industry insiders Kuma has partnered with Taisei Construction on scheme A, while Ito is working with construction companies Takanaka, Obayashi and Shimizu on scheme B.
Design A is ring-shaped with a latticed wooden roof and a rectangular well above a running track and pitch while design B also features an oval plan and has an atrium surrounded by a wavering glass shelter.
The winner will replace the 80,000-seat stadium design by Zaha Hadid that was scrapped in the summer, even though she had been working on it for over two years.
Ito and Kuma were among a host of high-profile architects and designers that petitioned against Hadid’s design in 2013. They claimed the stadium was “too big” for the city’s Yoyogi neighbourhood and that the architect’s design “could be better”.
Hadid teamed up with Japanese architecture and engineering firm Nikken Sekkei to renew its bid for the stadium in September, but was unable to enter the new competition as they couldn’t secure a contractor.
The winner is expected to be announced at the end of December and work is expected to start on the stadium in 2017 and it is scheduled to be completed by November 2019.
