大陸打通作戦
The Japanese 6th Area Army was formed on August 25, 1944 under the China Expeditionary Army primarily as a military reserve and garrison force for the occupation of the central provinces of China between the Yangtze River and the Yellow River. After the success of Operation Ichi-Go, many veteran units were transferred out of China to fronts in the Pacific War, which left the 6th Area Army to guard gains in central China. The 6th Area Army was demobilized at the surrender of Japan on August 15, 1945 at Hankou (part of modern Wuhan) in China, without having seen significant combat.
