A Crazy Time in Japanese Politics

Yuki Tatsumi

In this episode of The Diplomat’s Asia Geopolitics podcast, host Katie Putz is joined by Yuki Tatsumi, a longtime contributor to The Diplomat and a senior director at the Institute for Indo-Pacific Security (IIPS), to discuss the recent upheavals in Japanese domestic politics, including the decline of the LDP and the implications of new leadership under Prime Minister Takaichi Sanae. We explore Japan’s relationships with South Korea and China, Japan’s evolving defense strategy, and the expectations surrounding the upcoming visit from U.S. President Donald Trump.

Yuki commented that “Voters are increasingly frustrated with LDP and its coalition partners,” a frustration that “has been steadily mounting for the last 20-30 years.”
