A target locus of an attachment is determined while a calculation load for generating the target locus of the attachment is suppressed. A controller is configured to set a position of an arm distal end at a time when a contact detector detects contact of a bucket distal end with an excavation object at a start point of an arm distal end target locus. The controller is configured to receive information about a form of the arm distal end target locus in advance. The controller is configured to set a position for a finish point on the basis of an angle of a surface of the excavation object, an intersection angle between the arm distal end target locus and the surface of the excavation object, information about the form of the arm distal end target locus, and an offset amount about the finish point of the arm distal end target locus.
