Expert InsightsPublished Jul 31, 2025

Post–Cold War U.S.-Japan relations have been characterized more by continuity than change, even in times of leadership transition. Recent changes in leadership positions in the two countries at a relatively similar time necessitated reflection on the opportunities those leadership transitions afford and their potential. To better understand what the transitions mean for the two countries and for their bilateral relationship, RAND convened a conference at JAPAN HOUSE Los Angeles on March 10, 2025, that brought together experts to explore issues of relevance to the U.S.-Japan alliance with respect to the new administrations in both capitals. In these conference proceedings, authors summarize and provide a short analytical assessment of the conference.
