A New Security Consensus in South Korea?

Why It Matters

The shift signals a strategic realignment that could strengthen a US‑Japan‑Korea security bloc, reshaping East Asian geopolitics and counterbalancing China’s growing influence.

Key Takeaways

• South Koreans now rate Japan positively for first time.
• Prime Minister Takaichi tops global popularity poll among Koreans.
• China's coercive behavior drives Korean support for Japan alliance.
• US uncertainty pushes Korea and Japan to deepen trilateral cooperation.
• Young Korean voters influence pragmatic security stance over historical disputes.

Summary

The Asia Chessboard podcast examined a new security consensus emerging in South Korea, anchored by the Asan Institute’s latest public‑opinion poll. The discussion highlighted how Korean attitudes toward Japan have shifted dramatically, with a net‑positive rating for Tokyo and Prime Minister Fumio Takaichi surprisingly topping the global popularity rankings among Korean respondents.

Key insights from the poll reveal that China’s increasingly coercive diplomacy is the primary driver of this shift, prompting South Koreans to view closer Japan‑Korea security cooperation as essential. The survey also shows growing skepticism about U.S. policy stability under the Trump administration, reinforcing the desire for a reliable regional partnership. Younger voters, detached from historical grievances, favor pragmatic security choices over nationalist rhetoric.

Dr. Che Gong emphasized Takaichi’s firm stance against China as a catalyst, noting that the Japanese leader has avoided provocative historical comments and focused on security. He also cited President Lee Jae‑myung’s inaugural speech, which reaffirmed the ROK‑U.S. alliance while acknowledging China’s threat, illustrating a pragmatic, centrist approach among Korean leadership.

The implications are significant: a converging Korean‑Japanese security outlook, supported by the United States, could pave the way for a formal trilateral summit and deeper coordination against Beijing’s assertiveness. This emerging consensus may reshape East Asian alliance structures, influencing diplomatic, economic, and defense policies across the region.
