"The move in dollar/yen has certainly entered levels that are interesting," said Emma Lawson, a senior currency strategist at National Australia Bank. "Most people have moved towards expectations for a December or January taper and the yen is standing out as the currency to short."

Data on Thursday showed that U.S. retail sales rose 0.7 percent in November from a month earlier, compared with market expectations for a 0.6 percent rise. Last Friday, the closely watched non-farm payrolls report showed the U.S. economy created a higher-than-expected 203,000 new jobs last month.
"The dollar is broadly higher and I guess the Fed meeting next week has a lot to do with this," said Nizam Idris, managing director and head of strategy, fixed income and currencies at Macquarie Bank.
"The budget deal is also signed, so that's another hurdle out of the way," he added, referring to news late Thursday that the U.S. House of Representatives passed a two-year budget plan that would end some automatic spending cuts.
The prospect of another stalemate on budget talks had been seen by analysts as one reason why the Fed may push back the start of tapering its stimulus program.
Both Idris and Lawson said Friday's move in dollar/yen puts the currency pair on track for a move to the 105 level, possibly before year-end.

Kelly Teoh, a market strategist at trading firm IG, added: "The immediate level we are watching is 104. The dollar strength is going to continue and be exaggerated ahead of the FOMC meeting."
