I would SELL

GBPJPY 1H Technical analysis.
Remember - this is only technical analysis.
NFP can make pairs move different directions than technical shows.
This pair reached one higher tf trend line which stopped this movement up.
So i think price could start to make movements down again.
First we need to break this support area.
When price will be UNDER this zone then we can enter a sells.
Also remember that when Resistance or Support are broken, price tries to retest it.

Also this plan might be for longer period of time.
