Japan plans to increase the size of its ground forces in Okinawa Prefecture by about 850 troops to 2,300 to shore up defense of southwestern remote islands, Defense Agency sources said Monday.

The move could irritate China, because the plan is designed to deal with possible threats on remote islands in the southwest, including the disputed Senkaku Islands which are claimed by China.

What the hell are 2,300 ground troops going to do when okinawa is overrun with chinese? Absolutely nothing because by then it is already too late.
