The Kanagawa Prefectural Police and Maritime Self-Defense Force police jointly raided MSDF bases in Kyoto and Yamaguchi prefectures Tuesday in connection with the leak of classified data on the Aegis defense system, investigative sources said.
A joint Kanagawa-MSDF unit conducted the searches of Iwakuni Air Base in Yamaguchi Prefecture and the Maizuru Training Center in Kyoto, they said.
The bases are home to several MSDF officers and enlisted personnel believed to have played a role in leaking secrets pertaining to Japanese-U.S. security arrangements.
