Narrative:

We were flight sjc-nrt FL370, .83 mach out of radar coverage, but still in radio contact with zan. We were instructed to give position report at sya to zan. Waypoints to cross were sya, powal pasro. Powal was a non mandatory reporting point. Fob gave sya position report to zan and gave the eto for powal inadvertently for pasro. This eto was 36 mins before pasro. We were 6 mins behind flight plan so when we arrived at powal I double-checked numbers I noticed fob had given incorrect eto for pasro. Crossing powal, zan was told we would be crossing pasro. I should have caught this at the sya position report, but I did not. We attempted contact with zan but were unable to get them, which is a common occurrence. We had been instructed to contact tyo radio at pasro, so we called them up and informed them although we were not technically in their airspace yet. The fob was doing the radio and the airep form and I was doing the plotting, but you must double-check each other. I do double-check, but missed this one. So arriving at the non mandatory reporting point, powal, prior to pasro, the waypoint, we thought we had given the eto for, we noticed the mistake and realized ATC thought we would be at the next waypoint, pasro (a mandatory waypoint) at that specified time. We immediately notified tokyo radio. Double-check, double-check, double-check. I am going to be more careful to designate on my miscellaneous 14 flight plans which waypoints are mandatory and non mandatory reporting points.

Title: WDB ACFT GIVES ETO FOR WRONG WAYPOINT ON OVERWATER FLT.

Narrative: WE WERE FLT SJC-NRT FL370, .83 MACH OUT OF RADAR COVERAGE, BUT STILL IN RADIO CONTACT WITH ZAN. WE WERE INSTRUCTED TO GIVE POS RPT AT SYA TO ZAN. WAYPOINTS TO CROSS WERE SYA, POWAL PASRO. POWAL WAS A NON MANDATORY RPTING POINT. FOB GAVE SYA POS RPT TO ZAN AND GAVE THE ETO FOR POWAL INADVERTENTLY FOR PASRO. THIS ETO WAS 36 MINS BEFORE PASRO. WE WERE 6 MINS BEHIND FLT PLAN SO WHEN WE ARRIVED AT POWAL I DOUBLE-CHKED NUMBERS I NOTICED FOB HAD GIVEN INCORRECT ETO FOR PASRO. XING POWAL, ZAN WAS TOLD WE WOULD BE XING PASRO. I SHOULD HAVE CAUGHT THIS AT THE SYA POS RPT, BUT I DID NOT. WE ATTEMPTED CONTACT WITH ZAN BUT WERE UNABLE TO GET THEM, WHICH IS A COMMON OCCURRENCE. WE HAD BEEN INSTRUCTED TO CONTACT TYO RADIO AT PASRO, SO WE CALLED THEM UP AND INFORMED THEM ALTHOUGH WE WERE NOT TECHNICALLY IN THEIR AIRSPACE YET. THE FOB WAS DOING THE RADIO AND THE AIREP FORM AND I WAS DOING THE PLOTTING, BUT YOU MUST DOUBLE-CHK EACH OTHER. I DO DOUBLE-CHK, BUT MISSED THIS ONE. SO ARRIVING AT THE NON MANDATORY RPTING POINT, POWAL, PRIOR TO PASRO, THE WAYPOINT, WE THOUGHT WE HAD GIVEN THE ETO FOR, WE NOTICED THE MISTAKE AND REALIZED ATC THOUGHT WE WOULD BE AT THE NEXT WAYPOINT, PASRO (A MANDATORY WAYPOINT) AT THAT SPECIFIED TIME. WE IMMEDIATELY NOTIFIED TOKYO RADIO. DOUBLE-CHK, DOUBLE-CHK, DOUBLE-CHK. I AM GOING TO BE MORE CAREFUL TO DESIGNATE ON MY MISC 14 FLT PLANS WHICH WAYPOINTS ARE MANDATORY AND NON MANDATORY RPTING POINTS.
