Japan-Korea Treaty Day

What Is Japan-Korea Treaty Day?

June 22 is "Japan-Korea Treaty Day" (Nikkan Jōyaku Chōin Kinenbi) in Japan. On June 22, 1965, Japan and the Republic of Korea signed the "Treaty on Basic Relations between Japan and the Republic of Korea," commonly called the Japan-Korea Basic Treaty. The signing ceremony took place in Tokyo, and when the treaty entered into force on December 18 of that year, the two countries formally established diplomatic relations.

Background to the Treaty

After World War II, Japan and South Korea had no diplomatic relations, and their legal relationship remained unsettled. Even after the San Francisco Peace Treaty was signed in 1951, negotiations between the two countries dragged on, as political, economic, and legal issues needed to be resolved.
