 According to an operational map of military government units in Japan as of January 1946, the 90th Military Government is designated as a company-sized element operating in Kanazawa, Ishikawa Prefecture.In Kanazawa, personnel of the 90th Military Government supported Japanese administrators, maintained public services for the populace, and secured local artifacts and monuments (such as Kanazawa Castle) from potential looting and black market operations.Within the first sixth months of occupation, MacArthur began to reposition and redistribute military government units to better meet the needs of the nation, as there were not enough elements in their initial configuration to cover all of the prefectures.
