Two new Olympic stadium designs unveiled by Japan Sport Council

The Japan Sport Council unveiled two new stadium designs for the 2020 Tokyo Olympics on Monday, which blend in with the greenery-rich Yoyogi area and come in on budget.

Speaking about the technical proposals on the Council’s website, architect and critic, Takashi Moriyama, said:

Both designs use wood in their construction materials, and I think that’s an interesting aspect.

I think the idea of using wood in large structures may globally impact architecture.

The two new designs, which are apparently both by Japanese firms, are simply referred to as ‘Design A’ (top image) and ‘B’ (bottom rendering). The companies responsible for these designs have not yet been disclosed.

Design ‘A’ features outside walls embellished with plants in multiple layers, while design ‘B’ is notable in that it dispenses with walls around its oval outline, which is formed by 72 wooden pillars.

Both designs have a construction budget of ¥153bn (US$1.26bn, €1.14bn, £832m), putting them within the Council’s ¥155bn (US$1.28bn, €1.16bn, £848m) budget.

The design tender was opened in September and closed on November 16. The two proposals will now undergo screening by an expert panel and checks by relevant Cabinet ministers, with the final selection to be made by the end of the year.

Construction of the new stadium was originally planned to start at the end of this year, with completion slated for spring 2019, ready to host the Final of the 2019 Rugby World Cup, which will now instead take place at Yokohama Stadium. However, the new stadium will be ready in time to host the 2020 Olympics.
