Since 158 recent top, GbpJpy fell like a stone around 1k pips in a very short period of time.
At this moment the pair is trading exactly in support, a zone that acted as resistance in 2018 and 2019.
I expect a correction from this zone and 152.50 could be the buyer's target.
A clear drop under support would negate my outlook and could lead to continuation to the downside
If you decide to trade this pair you should be careful with SL
