Along similar lines that Yamashita Park in Yokohama was built with debris from the 1923 Great Kanto Earthquake, a new proposal has been made by the mayor of Urayasu, Hideki Matsuzaki to fill in a part of Tokyo Bay with debris from last years earthquake and tsunami which devastated northern Japan.
Uruyasu city is in Chiba prefecture, west of Tokyo, famous for its Disney parks.
A park would then be built on the land, helping to create a new green space in congested Tokyo while helping to clear the rubbish and debris left over the earthquake. The proposal is now under consideration by the government.
Despite losing its bid to host the 2016 Olympic Games, Tokyo is still planning to bid for the 2018 and 2022 World Cup finals.
FIFA requires the host city to have a stadium that seats at least 80,000 people for the opening and final games. The stadium that was used in the 2002 World Cup final in Yokohama only holds 70,000, making it necessary for Tokyo to build another stadium.
The 2010 World Cup will be held in South Africa while Brazil will host the 2014 World Cup.
