A direction presentation apparatus includes an instructed direction calculating unit which calculates, using a first angle in an external coordinate system representing an orientation of a camera that takes an image in front of a guided person and a second angle in the external coordinate system representing an orientation of a force sense presentation device that presents the guided person with a predetermined direction, an instructed force sense vector (hereinafter, referred to as a second instructed force sense vector) in a force sense presentation device coordinate system representing a direction to be instructed to the force sense presentation device from an instructed force sense vector (hereinafter, referred to as a first instructed force sense vector) in a camera coordinate system representing the direction to be instructed to the force sense presentation device.",
