Is it true or false that anti japenese hysteria on the west coast was caused in part by racism and fear

From what I've read about the anti Japanese hysteria, racism was a big part taker. they often discriminated against non-white immigrants.

pan-africanism or pan-africanism is a political, philosophical, cultural and social movement that promotes african twinning, the defense of the rights of african people and the unity of africa under a single sovereign state, for all africans, both africa as of the african diasporas.
