Its call sign was the Camp Division (陣兵団, Jin Heidan).

From 19 May 1944, the 63rd division also participated in Operation Ichi-Go, attacking Luoyang together with the 9th independent infantry brigade without much success until being rescued by the rest of the 12th army.

It fought in Soviet invasion of Manchuria, ending up in eastern Mukden by the time the fighting ceased 2 September 1945 without any formal treaty.

The division personnel were mostly taken prisoner by the Soviet Union, and were confined to labour camps in Mukden, Irkutsk, Russian Turkestan and other locations.

Although prisoners had started to return in November 1945, some soldiers remained in captivity, with the last of them dying in 1954.
