JAPAN’S cabinet approved the pact on Friday.
It will allow intelligence sharing in such areas as missile defence, North Korea’s nuclear weapons program and other regional security matters.
It has already been approved by South Korea and is to be signed in Tokyo later on Friday.
The pact reflects mutual concerns that more cooperation is needed to enhance security readiness, and is seen as a breakthrough in ties between the two neighbours.
Japan ruled the Korean peninsula as a colony for several decades until the end of World War II in 1945, and Seoul has often been wary of Japan’s postwar military development.
