Dad was a USAAF supply officer, remaining in the service after WWII. We were assigned to the Occupation Forces in '46, and I have some insights to the attitudes of post war allied and former enemy countries.
Upon arrival in Tachikawa, we occupied former officer quarters to which running water, bathrooms and steam heat had been added though the house walls were thin. We were encouraged to hire local help to aid the economy, and had a young teen house boy, Kato, and probably 50ish maid Kawasaki, spending each day with us. The Japanese as a whole in that central Tokyo area were accepting of their status, respectful and friendly, though some former officers Dad had to deal with were bureaucratic, and according to him, politely frustrating.
Jump ahead to early '70s, I tracked down Kato, who then was married and living in Northern Japan, and visited him. He spoke little English, though his teen daughters had enough skills that we enjoyed some good exchanges.
Per the C-46 pilot's experience, as I was then visiting a Fuji Industries manufacturing plant nearby, I was told that the region was considered much like our US hill people, a bit isolated, independent, feisty and suspicious of big city ways. That may have influenced the Japanese Lieutenant's posturing and show of force.
To carry this on a bit, we returned to the Rome, NY AFB for two years, then in '51, Dad joined Eisenhower's SHAPE staff in Paris, installing supply bases all over Europe and North Africa, later being based out of central Chateauroux, then for two years in Ramstein, Germany.
On the MATS ship (USNS Darby) across the Atlantic, we docked in Portsmouth for a few days, and Mom taxiied us to London and we spent time with locals. Even in '51, the Labour government still had them on wartime restrictions and rationing, and the locals had little access to sugar, butter or spices, which Mom charmed from the ship's cooks, and we delivered a trunkful (sorry, bootfull) of bags and big tins to our Portsmouth hosts.
We were surprised to find many Parisians distant and even resentful, and the French Communists/Socialists kept fomenting street riots, strikes and demonstrations, toppling the government several times during our three years there. We became accustomed to "YANKEE GO HOME" brushed prominently on walls and buildings by our recent allies.
By contrast, we were well received in the Black Forest region of then still divided Germany, with American, French, British as well as Russian sectors. Our base housing was only separated by a short woodland path and no security from the local villages, and we had many joint Boy Scouting and social activities. The allied sectors were dedicated to eradicating the wartime damage and reviving industry, with cleared rubble and new construction everywhere ... in contrast to the Russian sector, and ironically, the damaged sections of France. The only exception was in largely untouched and pristine Bavaria, during the war and then the vacationland of Germany. It also had been a political hotspot, the cradle of National Socialism, and when there on ski and snow holidays, we'd occasionally get surly attention or be ignored by mostly younger men who had not been of age to be conscripted ten years earlier.
