Twenty-Seventh Army (Japan)

The Japanese 27th Army was formed on March 16, 1944, as part of the last desperate defense effort by the Empire of Japan to deter possible landings of Allied forces in the northern Chishima Islands territories from northeastern Hokkaidō to Kamchatka during Operation Downfall. It was headquartered on Etorofu.

The Japanese 27th Army consisted mostly of poorly trained reservists, conscripted students and home guard militia. It was disbanded on February 1, 1945, and its units were incorporated directly into the Japanese 5th Area Army
