Expected increases in building projects and overseas visitors in the run-up to the 2020 Tokyo Olympics and Paralympics could raise Japan’s annual GDP growth by about one percent by 2018.
The figure is part of an estimate that the Bank of Japan released on Monday.
The central bank’s calculations assume that investment in building projects will total about 82 billion dollars in the expected peak year of 2018.
Such projects would include not only the main stadium and other sports facilities, but also those in the private sector, such as hotels.
The estimate also assumes increased demand in the tourism industry, with the estimated number of foreign visitors to Japan to reach 33 million in 2020 if the current rate of increase continues.
Based on these assumptions, the real-term GDP will be pushed up by 0.2 percent to 0.3 percent each year between 2015 and 2018.
The bank says new projects should be explored after the construction boom peaks in 2018.
