An element of Japanese manners by kneeling directly on the ground and bowing to prostrate oneself as touching one's head to the floor in order to show deference to a highly revered high-class person, as a deep apology, and to express the desire for a favor from said person.
For the pose itself (without the intent of deference or apology), see orz.
