Having said that, the future of USDJPY is in the lips of Yellen.
there might be a technical correction on the pair in favor or JPY towards 101.5 or even a little bit bellow, but on a long run, particularly of FED increases its interest rate, USD may cross the line of 102.5 and above towards 103.5 and 104.
There is the initial sign of an upward movement, with Tenkan Kijun twist bellow the Kumo Cloud. Lagging span is still in the price and didn't cross the Kumo but if it will, this will happen at the tighest part of the cloud, which means that the price may jump after a technical correction.
On the BoJ side, everything has been said, and there isn't an expected next move yet, we need to see and wait for FED's announcement.
