Despite reducing the original volumen last May to one billion 372 million dollars, the present design will be still more expensive than planned.

This plan reduced the size of the olympic stadium to 220 thousand square meters, 70 thousand meters less than originally intended.

Besides, the minister of Sports, Hakubun Shimomura, proposed that if the new olympic stadium were built without the retractile roof and the number of seats were reduced, the cost and time of construction would be diminished.

Despite those modifications, the final price of the project could go up by 700 million dollars due to the increase in prices of materials, said sources of the Government to the state network NHK.

New modifications will be introduced to try reduce the cost even more of the stadium and added that until then no contract will be signed with the companies in charge of the stadium to start construction.
