Men!

That's the very first strike in Kendo that is learned. It is a cut to the head. a straight beautiful arc. 

It's a 45 degree angle from over the kendoka's head, extending the angles between the wrist and elbows simultaneously. 

The strike is completed when the tsuba (hilt) is in front of the striker's face. Upon impact the striker grips the shinai to let inertia finish the hitting.
