The Japanese government is arranging to compile a stimulus package of at least 20 trillion yen about ($188 billion) to help the domestic economy emerge from deflation and fend off possible adverse effects of Brexit, sources close to the matter said. 
The sources said that the government initially envisaged compiling a stimulus package of somewhat more than 10 trillion yen. But the size is likely to double as the package will now include projects for fiscal 2017 and beyond and increase "zaito" low-interest government loans by 6 trillion yen, according to (Kyodo) News Agency. 
There is also a possibility the size of the package and public expenditure may increase even further, depending on agreements between the government and the ruling coalition of the Liberal Democratic Party and Komeito party, the sources said.
