There is a ship named CETUS LEADER that recently left Jacksonville, FL and is scheduled to be in NY tomorrow; however, I can't find a ship track history that goes back far enough to see if it came from Japan. The arrival port and date is what my dealership told me, but they don't know the ship's name. There happens to be another ship, PLUTO LEADER that just left Jacksonville too, but it's heading to Baltimore. Both can be tracked here:

If anyone discovers longer track histories, please pass on.
