Prime Minister Sanae Takaichi on Dec. 23 cited the need to ensure Japan can maintain “force sustainment” in a military conflict as a reason for swiftly revising three key security documents.
“Because our security environment has dramatically changed, Japan needs to proactively enhance our capabilities by ourselves,” she said at a Tokyo meeting with managing editors of Kyodo News member companies.
Force sustainment refers to the ability to continue fighting a war over the long term in terms of ammunition, fuel and equipment.
Takaichi emphasized the need for Japan to be prepared for an extended conflict like the war between Russia and Ukraine.
She also said warfare strategies have shifted since 2022, when the current three security-related documents were worked out to designate Japan’s basic diplomatic and security policy.
The prime minister, referring to the Russia-Ukraine war, noted that unmanned drones have been increasingly used to conduct swarm attacks against a target.
