Residents near U.S. Kadena Air Base in Okinawa were awarded about ¥30.2 billion ($267 million) in noise pollution redress Thursday, marking the largest damages payment ever levied against the Japanese government.

But a request by 22,000 residents to ban nighttime and early morning flights at the biggest U.S. air base in East Asia was turned down by the same court. The number of plaintiffs was the largest ever to participate in such a lawsuit, their lawyers said.

The ¥30.2 billion in compensation by the Okinawa branch of the Naha District Court far exceeds the previous record of ¥8.2 billion for noise pollution near U.S. Naval Air Facility Atsugi in Kanagawa Prefecture.
