context_section_description: After Japan's surrender, the preparations for invasion proved unnecessary.
   In December 1945, the 90th Military Government deployed to Japan under the Headquarters, Eighth United States Army and General Douglas MacArthur, the Supreme Commander of the Allied Powers (SCAP). Personnel likely wore the Eighth Army patch once they deployed to Japan.
  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.
