Wasn't aware of that, my bad. In Singapore (where I'm from) it doesn't have any negative connotation.

only in the usa because of war propaganda shame :(

it's pretty common and non offensive elsewhere. not sure about uk... but other English speaking counties and latin countries use the term just fine

But it's okay to call the English "Brits".

It's a legacy from WWII. See: https://en.wikipedia.org/wiki/Jap

try calling one a lobsterback and see what happens.

different groups have different insults. welcome to reality.
