Eighteen people were injured, with one breaking a leg, when a passenger plane hit turbulence en route from Tokyo to Washington, Japanese police said on Saturday.
The United Airlines Boeing 747-400 was carrying 245 passengers and crew when it hit turbulence over Alaska, seven hours from Tokyo's Narita airport, a police officer at the airport said.
Police initially said more than 20 people were hurt, but later revised that figure down to 18, including at least one person who suffered a broken leg.
Footage broadcast by NHK showed rescuers carrying some of those injured from the plane. It reported three people were hospitalised.
