The Okinawa Prefectural Assembly on Monday unanimously adopted a resolution protesting last week's nonfatal crash-landing of a U.S. military helicopter and demanding that the use of helipads be halted in the training area it strayed from.

The resolution said the U.S. has increased training exercises over private land since six helipads were built in the U.S. Northern Training Area. Some of the helipads are close to residential areas.

Both the resolution and a separately adopted statement addressed to Prime Minister Shinzo Abe said last Wednesday's emergency landing by the CH-53E transport, which took place a few hundred meters away from Okinawan homes, was "on the verge of being a major disaster."
