This is the biggest lost of USDJPY since 1998 : 18 years one time. So it's a rare phenomenon.
I have a pessimistic view about current situation of global economy. There is no bright signal.
Despite the effort of BOJ to increase stimulus and depreciate Yen, I think Yen will receive more bid.
Look at on the chart, I draw a long long term , USDJPY officially break this , signal for more loss.
I believe USDJPY would fall to 105 level in the medium term.
