What happened to USDJPY suddenly?

Just noticed USDJPY dropped pretty heavily at what seemed like a not-important time of day. Was curious if anyone knew exactly what happened.
I did read on Twitter at the exact moment it dropped, that former President of Japan Shinzo Abe collapsed while giving speech or something. A gunshot was heard. Very odd for Japan.
So I’m curious if for some reason that affected the price. No idea.
