Japan protests after U.S. Marine accused of killing woman in Okinawa

A U.S. Marine has been accused of killing a woman in Okinawa, prompting official Japanese protests and threatening to revive local tensions over the American military footprint in Japan. The incident is unverified in detail and its diplomatic fallout is still unfolding. It matters because Okinawa hosts a large share of U.S. forces in Japan, and such cases historically strain the bilateral alliance and fuel base-opposition movements.
