"In terms of Japan-South Korea cooperation, we wish for further promotion of security-related cooperation," Chief Cabinet Secretary Yoshihide Suga told reporters, as quoted by Yonhap.
The General Security of Military Information Agreement (GSOMIA) has been in the making for years. The two nations came close to signing the pact in 2012 but failed after protests in Seoul.
Koreans are reportedly suspicious of military deals with Japan, which ruled Korea for decades until its defeat in World War II in 1945.
The intelligence sharing pact is aimed at countering North Korea’s aggression, according to Yonhap. The countries want to exchange information on the progress of Pyongyang’s nuclear and missile programs after the North staged its fifth and largest nuclear test last month.
