Late in 1944, as the course of the war went against Japan after the disastrous Battle of Imphal, Kimura was again assigned to the field, this time as commander in chief of the Burma Area Army, defending Burma against the Allied South East Asia Command.

Reinforcements and munitions were short, and Imperial General Headquarters entertained the unsupported hope that Kimura would be able make his command logistically self-sufficient.
