Narrative:

On ground at nrt, I inserted wrong waypoint into INS 42N instead of 44N. Rechks by myself, first officer, and so did not catch error. After passing 42N 160E company flight asked what track we were on. We plotted position on chart, compared mileage to next position with flight plan, INS, and off plotting chart. We determined we had begun to track south off course. A correction back to course was made immediately. Flight proceeded with no further incident. Waypoint times indicated less than a min difference. Factors: fatigue (9 hour time zone difference). Also had 11 day trip which included multiple pacific xings. Single crew.
