The India-Japan Defence Ministers’ Meeting of 2026: what happened?

India and Japan are the two big democracies at either end of the Indo-Pacific. Both depend on safe sea lanes. Both worry about attempts to change borders by force. Their defence ties have grown slowly. This meeting adds a formal maritime pact and moves towards joint equipment and shipbuilding.

The Memorandum covers cooperation between the Japan Maritime Self-Defense Force and the Indian Navy.
It includes information sharing in Maritime Domain Awareness, Search and Rescue, and HADR.
The ministers opposed unilateral actions that impede freedom of navigation and overflight, and attempts to change the status quo by force or coercion.
They agreed a Working Group at Director-General/Joint Secretary level to coordinate all areas of cooperation.
