Japan finds itself at a critical crossroads. With recent leadership change in Tokyo, an increasingly challenging strategic environment, and its defence expenditure projected to double, Japan is reshaping its strategic posture in ways not seen in decades. Meanwhile, Donald Trump’s return to the U.S. presidency following the November 2024 election has raised fresh questions about the future of the U.S.-Japan alliance - long regarded as the cornerstone of regional security - and the implications for alliances, regional stability, and global order. Against this backdrop, the ever-closer Australia-Japan security partnership is taking on heightened importance, with some observers now likening it to a de facto alliance. In this panel discussion, four leading Japanese experts will explore these developments, their potential impact on Indo-Pacific security, and what they mean for the evolving Australia-Japan security relationship.
