An Alitalia Boeing 777-200, performing flight AZ-784 from Rome Fiumicino (Italy) to Tokyo Narita (Japan) with 242 passengers and 14 crew, was descending towards Tokyo when the aircraft encountered turbulence.

The fasten seat belts signs were illuminated at that time. Three of the flight attendants who were still working to prepare the cabin for the arrival received minor head injuries as result of the turbulence encounter. The aircraft continued for a safe landing about 20 minutes later.

The aircraft was able to depart for the return flight AZ-785 on schedule.
