Selected Aspects of Japan’s Defense Strategy in the Indo-Pacific Region in 2021—2025

The article analyzes certain aspects of Japan’s defense policy in the Indo-Pacific region under the Kishida and Ishiba Administrations from October 2021 to October 2025. The author examines the key trends in the impact of Japan’s defense modernization on the development of the IndoPacific security system and also focuses on Tokyo’s evolving role within the U.S. – Japan alliance as a key factor in Japan’s increasing participation in regional diplomacy. It is noted that the U.S. gradual transition to “strategic autonomy” from the USA has contributed to Japan’s expanding foreign policy engagement in the region, which is taking place amid an unprecedented increase in Japan’s defense budget. Furthermore, as part of the revision of Japan’s foreign policy strategy, the study of the modernized Free and Open Indo-Pacific concept, presented in March 2023 to adapt Japan’s strategic priorities to new geopolitical realities and contemporary global challenges, has acquired particular significance. Following an analysis of the implementation of the plans reflected in the updated concept, it is concluded that Japan faces certain challenges in harmonizing its foreign policy approaches with India, one of its most important regional partners. New Delhi’s reluctance to compromise its sovereignty for the sake of deepening relations with Tokyo is noted, but Narendra Modi’s willingness to accommodate on issues of mutual interest is also emphasized. The article also examines Tokyo’s approach to building networked relations with Japan’s key partners in the IndoPacific region: the Republic of Korea, the Philippines, and Australia. The significant role of the United States in shaping such ties, as well as their increasingly military focus, is highlighted. Furthermore, it is emphasized that the Japanese authorities’ plans to revise its foreign policy approaches, which could lead to an escalation of the already tense situation in the region, are particularly concerning.
