A group of about 100 people led by architect Fumihiko Maki voiced in a petition against the Japanese government's current plan on the New National Stadium for the 2020 Tokyo Olympics, according to local media Friday.
They said the current design of the stadium potentially spoiled the landscape in Tokyo's Meiji Jingu Gaien area, a major urban green space in the country, said Japan's Kyodo News.
In the petition presented Thursday to the sports ministry and Tokyo metropolitan government, the group said "given a total floor space double to triple the past main Olympics venues such as London and Athens, we are also concerned about its costs for safety, maintenance and management," Kyodo quoted the petition as saying.
The group called on the authorities to modify the scale of the stadium to a combination of around 50,000 permanent seats and temporary seats from current 80,000-permanent-seat plan.
They also said that the new stadium should be one that would be appropriate for an aging society experiencing a declining population and urged the government to fully explain about the project to the nation, said the report.
The renovation plan designed by a British-Iraqi architect aims to make the existing national stadium an all-weather facility with a retractable roof.
According to the plan, the national stadium will be built on a 113,000 square meter site, about 1.6 times larger than the current site, and will have a total floor space of 290,000 square meters, about 5.6 times larger than the existing stadium.
