The two new stadium designs appear to be much smaller and less expensive than Zaha Hadid’s original stadium design. Her futuristic proposal, which had won the competition in 2012, was scrapped earlier this year due to escalating costs and public outcry. Both Ito and Kuma were among critics who petitioned against Hadid’s design in 2013, claiming it was too large and incongruous with the surrounding environment. In comparison, the two new proposals clock in at under the ¥155 billion budget and appear to take a more ecologically sensitive approach to the nature-protected Yoyogi area.

“Both designs use wood in their construction materials, and I think that’s an interesting aspect,” said architect and critic Takashi Moriyama, according to the Japan Times. “I think the idea of using wood in large structures may globally impact architecture.” Design A, which is believed to involve Toyo Ito, is covered with a latticed wood roof and a greenery-covered facade. Scheme B, thought to include Kengo Kuma, features an open, undulating glass roof and is surrounded by 72 wooden pillars.
The winner will be announced at the end of December. Construction is expected to begin in 2017 for completion in November 2019.
