Japanese Yen rallied against US Dollar on Friday, following the release of the Bank of Japan meeting minutes, which revealed that officials are cautious about the rising cost of the quantitative easing.
The central bank had pledged at the last April meeting to keep interest rates at near one-year lows.
The cautiousness demanded by the Bank of Japan's officials reflects the increased awareness of the risks that surround the quantitative easing program when implemented for a long time to support economic growth and avoid recession.
This comes at a time of concern and uncertainty about global economic growth and the US-China trade war.
The G20 summit will lunch in Japan next Friday and will continue until Saturday, during which the most prominent issues on the world stage will be discussed.
In terms of trading, by 19:06 GMT, US dollar fell against Japanese Yen by 0.2% to 107.1, with the highest at 107.4 and the lowest at 106.7.
