Hitting an All-Time Low

In the early months of 2019, Japan-South Korea relations have continued a downward spiral. In their dealings with the radar lock-on dispute and a South Korean court ruling on forced laborers, both Seoul and Tokyo responded to the other’s action negatively, reaching the point of suspending all senior-level defense exchanges for the first half of the year. While recent developments may point to yet another period of all-time low in Seoul-Tokyo relations, it is possible that the year 2019 may signify the beginning of a new trend at a deeper level. That is, Seoul and Tokyo do not regard the other as a valued partner in their long-term national security strategy, even when addressing nuclear and missile threats from North Korea. On the Japan-North Korea front, once the biggest regional champion of the US “maximum pressure” campaign, Japan has continued to reckon with the region’s sudden turn toward diplomacy with North Korea and made some policy adjustments for better alliance coordination with the United States.

Unfortunate Circumstances and Escalating Tensions

Fall 2018 represented a turning point in Japan-South Korea ties as an uneasy truce between the two countries gave way to escalating tensions. South Korea’s Supreme Court ruled that two Japanese companies must compensate 10 South Koreans forced into labor during Japan’s occupation of the Korean Peninsula from 1910 to 1945. South Korea’s decision to dissolve the foundation built to implement the 2015 “comfort women” agreement between Seoul and Tokyo, though not unexpected, also added to the general atmosphere of growing tension. As 2018 came to a close, tensions flared as Japan alleged a South Korean Navy destroyer locked onto a Japanese Maritime Self-Defense Force plane with a radar used for targeting weapons – a claim Seoul vigorously denies. On the Japan-North Korea front, Prime Minister Abe’s willingness to meet Kim Jong Un characterized Tokyo’s response to the Trump-Kim summit amid increasing uncertainty concerning Japan’s role in talks on denuclearization of North Korea, but with no real change of Japan’s North Korea policy.
