The Japan Defense Force (Japanese: 防衛隊) is the military force of Japan in the Front Mission series.

It has a website in Front Mission 3's in-game network, whose contents can be viewed here.


When Japan was admitted to the OCU in 2026, it appears to have abolished the Article 9 of its constitution which forbids them from sending any military forces outside their borders, so Japan can participate in peacekeeping missions and joint military operations within the OCU. The Japanese military then subsequently renamed by simply changing the "Self-Defense" part of its name into "Defense".
