Pritzker lauretes Toyo Ito and Fumihiko Maki have launched a petition against the construction of new Tokyo Olympic Stadium, which is to be designed by Zaha Hadid. It was originally initiated by a renowned anthropologist Shin-ichi Nakazawa, and Toyo Ito and Fumihiko Maki have joined the protest. They have pointed out the fact that 1) the selection process is unclear, 2) the construction process is unclear, 3) the excessive cost, and 4) neglecting the historic environment.
Ito and Maki have proposed an alternative plan which is to renovate the existing stadium. The cost of the renovation is estimated to be less than half the cost of building the Olympic stadium.
