"Pauses in operations are not uncommon and are viewed as a responsible step to refresh and review best practices and procedures so our units remain capable, safe, and ready", officials with Marine Corps Headquarters said in a statement.
Japan's Defense Ministry will allow USA military MV-22 Osprey flights to continue in the country, despite previously calling for them to be grounded after a fatal crash killed three marines.
But on Friday, Japan's defence ministry issued a statement saying that the U.S. military "is taking reasonable measures" and "the USA force's explanation that it can conduct safe flights of MV-22 Ospreys is understandable".
According to a United States official cited by AFP, the crash occurred after the Osprey clipped the back of the "USS Green Bay" while trying to land on the amphibious transport ship.
The crashed plane was one of the Ospreys deployed at the Futenma air base in Japan's southernmost island prefecture of Okinawa, which hosts the bulk of USA forces in the country.
An Australian naval ship has found the wreckage and divers were preparing to try to locate the three missing Marines, the country's defence ministry said Monday in Canberra.More news: Stocks, dollar extend slide as US-North Korea tensions intensify

Other critics have slammed the Osprey - which takes off and lands like a helicopter but flies like an airplane - as being unsafe.
An MV-22 Osprey crashed off the eastern coast of Australia on Saturday, leaving three U.S. Marines dead.
Japanese authorities in Hokkaido and Okinawa have been calling to ground all Osprey aircraft over safety concerns.
The aircraft has been involved in a series of fatal incidents, mostly in the United States.
A Camp Pendleton-based Marine was one of the victims.
Thirteen marines were killed by terrorists in Marawi last June in what is considered as the most intense firefight since clashes broke out in the besieged city.
