In other news from Japan, officials on the island of Okinawa have sued the Japanese government in the latest bid to block construction of a new U.S. military base. Okinawa authorities say the Japanese government illegally overrode Governor Takeshi Onaga’s order halting construction earlier this year. Okinawa is home to more than half of the 50,000 U.S. troops stationed in Japan. For decades, residents have demanded the expulsion of U.S. troops, citing environmental concerns and sexual assaults.
