The governor of Okinawa expressed guarded hope Wednesday that Donald Trump's victory in the U.S. presidential election may lead to a reduced military presence in the prefecture, where most U.S. military facilities in Japan are located.

During the campaign, Trump complained that Japan shoulders too little of the cost of stationing U.S. forces there, and said he would consider withdrawing those military forces.

"While I am hopeful about the kind of measures (Trump) will take regarding the Okinawa base issue, I would like to keep a close eye on it," Gov. Takeshi Onaga told reporters at the prefectural government office. For years, the prefecture has called on Tokyo and Washington to ease its burden from hosting U.S. military bases.
