USD/JPY decline extends to more than 100 pips as technical levels crack. What’s next

This is starting to get interesting
There isn’t a big reason to be buying yen or searching for safety today.
S&P 500 futures are down 4 points after an 8 point rally to a fresh all-time high on Friday. I could see the Friday gain being wiped out because it came in a super-quiet market but it doesn’t sap USD/JPY too much.
