Japan and the United States agreed Thursday to have two Japanese air-traffic controllers spend a month at the U.S. Kadena Air Base in Okinawa Prefecture from mid-October to undergo training, the Transport Ministry said.

During the training, to start Oct. 16, the Japanese will observe air-traffic control operations at the central Okinawan base but will not take part in operations.

The agreement follows an earlier accord made under the Japan-U.S. Joint Committee on the Status of Forces Agreement in June, which was in line with a U.S. decision in March to return control of the radar system at the Kadena base to Japan, the ministry said.
