Prime minister says Japan will redo the plans for the costly Tokyo 2020 Olympic stadium

In a major reversal, Japan's leader has announced that the plans for the main stadium for the 2020 Olympics will be redone because of spiraling costs.

Prime Minister Shinzo Abe told reporters Friday that the government would start from a "zero base" in reconsidering plans.

The proposed stadium faced growing criticism as the estimate of it cost rose to 252 billion yen ($2 billion).
