wikipedia is way off their number.. many more died in months after and years. from the effects of the bombs. After that war they were called “Japs” and hated. It took a long time to get that name off the lips of most.
To me as a kid ( born '49 ) in the fifties, The War was ancient history. WWII comics and TV dramas were prominent through the mid sixties, though, and I'm sure the comics, at least, used the term "Jap", as a matter of historicity. Honestly, I don't think it was a term of hatred, as I heard it, but simply an historical artifact. By that time the Japanese were being recognized as an economic rival, and I listened to "The Lion Sleeps tonight" on my SONY miniaturized transistor radio ( These were known as "SONYs" ) and felt I was part of the future.
