Kengo Kuma
The original plans for the new stadium were scrapped in July 2015 by Japanese prime minister Shinzo Abe, who announced a rebid after a public outcry because of increased building costs. As a result, the new design was not ready for the 2019 Rugby World Cup, as originally intended. A new design created by architect Kengo Kuma was chosen in December 2015 to replace the original design and was completed in November 2019.
