Japan defense chief visits Seoul for first time in 11 years, Japan-Korea SAR drills resume after nine-year freeze

Summary

Japanese Defense Minister Shinjiro Koizumi visited Seoul on June 28 for the first time in 11 years, meeting South Korean counterpart Ahn Gyu-back for the sixth round of bilateral defense talks. The two sides resumed joint maritime search-and-rescue exercises after a nine-year suspension and agreed to expand cooperation on artificial intelligence and advanced defense equipment. Both ministers reaffirmed the denuclearization of the Korean Peninsula and committed to closer trilateral coordination with the United States.

The split

The Nikkei framed the meeting as a structural normalization of a relationship long distorted by wartime history disputes, while IBTimes SG emphasized the 11-year gap in ministerial visits as evidence of how contested the partnership remains. Pakistani and Southeast Asian outlets highlighted the North Korea and US-alliance dimensions, treating the meeting as a signal of tightening Northeast Asian security architecture.

By the numbers

• 11, years since a Japanese defense minister last visited Seoul
• 9, years since the bilateral maritime SAR exercise was last held
• 6th, round of Japan-Korea defense minister talks held under current protocols
• 3, countries explicitly mentioned in the closer coordination pledge: Japan, South Korea, United States

Why it matters

A functional Japan-South Korea security channel reduces the coordination gap the US has long worried about in Northeast Asia. The SAR exercise resumption is operationally meaningful given North Korea's continued missile testing.

What to watch

• Whether Japan and South Korea advance a bilateral defense equipment treaty or remain at MOU level
• North Korea's response, if any, to the joint denuclearization statement
• Whether Koizumi and Ahn schedule a follow-up with US Secretary of Defense before year-end
