Japan will start construction of a new national stadium for the 2020 Tokyo Olympics in January or February.

Sports minister Hakubun Shimomura says the government will choose a new design and builder through an international competition with the aim of completing the stadium by the spring of 2020.

The government scrapped the original design of the stadium on Friday because of soaring costs which reached $2 billion. Construction of that stadium was supposed to begin in October and be completed in May 2019 in time for the Rugby World Cup in 2019.

Shimomura also said he is considering setting up an independent panel to find out why construction costs of the scrapped stadium were so high.
