Procedure; Weather; Environment - Non Weather Related; Company Policy
Captain signed for flight plan with landing fuel of 18;100 lbs. No significant weather planned departure; enroute or destination. No significant maintenance issues. Flight was flown as planned with the exception of 2 deviations for unforcasted convective areas and a vector around military airspace in PAZA.Flight arrived at top of descent with a negative fuel score of 2.0. After normal early descent (ELGAR arrival via MELON) and vectoring off arrival; several flights ahead on arrival received holding instructions and were informed RJAA was changing runways. The flights were given expected clearance times which; if similar for our flight; would result in landing with emergency fuel. When our flight was given holding instructions we informed ATC we were unable to accept holding for fuel. After ATC again gave holding instructions we informed them we needed to divert for fuel. We were given a vector for ZZZZ and proceeded to plan for diversion. Dispatcher was notified but not consulted due to time constraints. ATC subsequently informed us that there would be holding for arrival into ZZZZ due to coordination. We requested clearance for landing at RJAA or ZZZZ whichever could be coordinated soonest. Uneventful approach and landing were made at RJAA. Landing fuel was 13;000 lbs.
B777 First Officer reported multiple deviations and delays in flight resulted in the aircraft landing with emergency fuel.
