Share
On August 24, 2026, the International House of Japan (IHJ) hosted a public forum for the Japan-South Korea Joint Opinion Poll. The event welcomed Chaesung Chun, president of the East Asia Institute (EAI); Yul Sohn, EAI distinguished fellow and professor at Yonsei University; and Jung-Hwan Lee, professor at Seoul National University.
The purpose of this forum was to report on and discuss the results of the “Japan-South Korea Joint Opinion Poll”* jointly conducted by IHJ and EAI. The survey focused on Japan-Korea relations, Japan-U.S.-Korea security cooperation, Japan’s defense, and perceptions of the United States, China, and Taiwan. The results of this year’s survey were made public at a joint Japan-Korea international press conference held in Seoul on August 3.
Approximately 30 participants, including experts from academia and the media as well as university students, attended the event, which was structured in two parts as follows.
Session 1: Presentation of Survey Results
In Session 1, Professor Yul Sohn and President Chaesung Chun from EAI took the stage and delivered a 20-minute presentation on the findings and analysis from the South Korean perspective. Next, Ken Jimbo from IHJ took the stage to share the findings from the Japanese perspective.
Session 2: Policy Implications Derived from the Survey Results and Future Outlook
In Session 2, experts from Japan and South Korea each shared comments for approximately 15 minutes. From the Japanese side, Professor Naoko Eto, Visiting Senior Fellow at the Institute of Geoeconomics (IOG), and Professor Junya Nishino of Keio University took the stage; from the South Korean side, Professor Jung-Hwan Lee spoke, each offering insights from their respective fields of expertise.
Following the presentations and comments in both Session 1 and Session 2, time was set aside for a question-and-answer session and a general discussion. Participants offered a wide range of comments, covering topics from the background of mutual perceptions between Japan and South Korea to Japan-U.S.-South Korea diplomacy, and even extending to sports and exchanges among younger generations, creating a lively forum for the exchange of views that transcended generations and organizational affiliations.
*In 2025, a trilateral survey involving Japan, the United States, and South Korea is being conducted, with the addition of the Korea Economic Institute of America.
