The 2020 Tokyo Olympics and Paralympics are expected to generate from ¥25 trillion ($208 billion) to ¥30 trillion in sales and revenue for the economy from 2014 to 2020, the Bank of Japan said Monday.

The estimates reflect an increase in infrastructure investment related to the sporting extravaganza and tourism, the central bank said.

Tourism has been surging, and visitors to Japan are expected to reach 33 million in 2020 if the current trend continues, surpassing the government's goal of 20 million by that year, the BOJ said.
