On October 21, 2025, the Indian Navy’s frigate INS Sahyadri docked at Yokosuka, Japan, as part of a nearly three-month expedition across East Asia, signaling India’s growing maritime diplomacy in the Indo-Pacific. This port call coincided with the formal inauguration of Japan’s new Prime Minister Sanae Takaichi, known for her hawkish stance and admiration for Margaret Thatcher, who has emphasized a stronger military posture and constitutional amendments to bolster Japan’s defense. The visit underscores India-Japan’s strategic partnership, including joint naval exercises such as JAIMEX, aimed at enhancing interoperability and joint maritime security amid regional tensions, particularly from China’s assertiveness. India’s efforts to deepen maritime cooperation involve increased training, R&D collaborations, and seafarer employment opportunities, reflecting a shared commitment to maintaining a free, open Indo-Pacific region. This evolving partnership is part of broader efforts by both nations to counterbalance regional adversaries while strengthening diplomatic, military, and economic ties in an increasingly complex geopolitical landscape.
