The 52nd Division was a provisional unit, intended to form sub-units usable by other military units, rather than being used itself. In particular, the 16th Mountain Artillery Regiment and 52nd Cavalry Regiment were detached in October 1943. The division was renamed to the Kanazawa Mobilization District in 1941 (not to be mistaken with the Kanazawa Mobilization District Command formed in 1945).
In January 1944, the 52nd Division was reformed as marine division, absorbing artillery and engineer units into infantry regiments, and sent to Chuuk Lagoon, to be incorporated into the 31st Army formed on 18 February 1944. As the Allies had bypassed the Japanese forces at Chuuk Lagoon (Truk) and the other eastern Caroline Islands, the 52nd Division saw little action or hardship besides the U.S. Navy's attacks during Operation Hailstone.
