The 28th Division was tasked with the defense of the
Manchukuo capital, and the neighboring areas of
Harbin and
Qiqihar under direct control of
Kwantung Army. With the start of the
Battle of Saipan 15 June 1944, its 36th Infantry Regiment was sent to
Saipan, but returned to division soon as
Saipan was lost before 36th regiment could arrive. Simultaneously, the 28th Division was reassigned to the
32nd Army in June, 1944 and reassigned to the
Ryukyu Islands, specifically to
Miyakojima (where it based its headquarters) and
Ishigaki archipelago. Its former garrison and some left-over troops were incorporated into
112th division. In the
Battle of Okinawa, the 28th Division main positions were never invaded, but were heavily bombed and subject to coastal bombardment. As all higher-ranking officers of the
32nd Army were killed, Naumi Toshiro, commander of the 28th Division, signed a surrender document for the
32nd Army after the
surrender of Japan. The division was disbanded 13 December 1945. ==See also==
