JPY movement after BOJ comments - looking at my pairs

Watching the JPY today, it's pretty interesting seeing it gain more than 1% after the BOJ Governor's comments, sitting around $JPY 37.2677. They're still talking about easing, but there's this underlying shift in tone that markets seem to be picking up on. This makes me re-evaluate my EUR/JPY and GBP/JPY short positions, especially since I'm seeing a bit of a rally in safe havens. Curious to see if this is just a knee-jerk reaction or a more sustained shift in sentiment, particularly with US CPI next week.
