I experienced pretty much the same thing in Japan and Kowloon (Hong Kong) way back during the Vietnam War when I was in the Navy.
My father’s generation of black soldiers and sailors often said that they had similar experiences during WWII in the “Far East.” They said that this disdain for black people by Asians started when white GI’s during the war disparaged black soldiers and sailors, telling Asians that black people had tails, for starters.
Excellent piece.
