Japan-South Korea Relations at the Lowest Point since Diplomatic Normali- zation Since normalizing their diplomatic relations in 1965, Japan and South Korea have repeatedly experi- enced rough patches in their bilateral relations due to historical, territorial and other issues. However, in all instances, centripetal forces generated by common interests in such areas as national security and the economy were strong enough to outweigh the centrifugal forces that tugged at the two nations. Consequently, while occasionally experiencing significant shaking, bilateral relations always gradually returned to their original trajectory. However, Japan-South Korea relations cooled rapidly after then-President Lee Myung-bak set foot on Takeshima Island (referred to as “Dokdo” in South Korea) on August 10, 2012. Subsequently, both sides set off centrifugal forces that sent bilateral relations into a serious slump that did not allow centrip- etal forces to function as before.
