What is India Japan Defence Partnership?
India Japan Defence partnership is a strategic relationship aimed at deepening security cooperation in the Indo-Pacific. Japan is transforming its defence posture, moving from a restrained, US-dependent model to a more proactive military power with long-range strike capabilities, strengthened air and missile defence, and expanded cyber and space capabilities.
Japan’s defence spending is rising to around 2% of GDP, with a revitalised defence industrial base, eased arms export restrictions, and a new Official Security Assistance programme. The partnership with India includes a 2+2 dialogue, a logistics agreement, regular tri-service exercises, and a first bilateral defence co-development project on the UNICORN naval communications antenna.
Why is India Japan Defence in News?
India Japan Defence is in the news because Japan’s Defence Minister Koizumi’s visit to India after consultations in Canberra signals new directions in Indo-Pacific security cooperation. Japan’s 2022 National Security Strategy explicitly identifies China, North Korea, and Russia as security challenges—a historic departure from its traditional posture.
The visit is expected to push bilateral defence cooperation beyond “incremental” towards “operational and technological weight.” However, defence industrial cooperation has been painfully slow, and experts argue that India must match Japan’s commitment and urgency.
