What's next for USDJPY ?

As USDJPY breaks above 103.50s for the 3^rd time this year, will traders ride the bandwagon siding with the expectations of fresh BoJ stimulus offseting any growth challenges from this month's Japanese tax hike, or will a stock market selloff weigh on the pair as it has done in the past? We know that bond yields usually move in tandem with yen pairs. We also know the Fed is expected to taper in April, alongside dovish (accommodative) talk from Fed chairwoman Yellen. So where does all this leave USDJPY?
