how much more fuel will the heavier 747 use, on a trip from Tokyo to Honolulu?

That depends if the Sumo wrestlers are in Sandanme, Jonidan or Jonokuchi divisions.
But all things being equal, the ladies' plane will use about 700 gallons less fuel than the wrestler's plane.
Although one would expect the ladies to have substantially more luggage, possibly negating any real fuel savings.
