Angry protesters took to the streets Sunday in Tokyo's Shin-Okubo district, home to many Korean shops and restaurants, describing the Korean residents there as "cockroaches" and calling for their immediate "extermination."

It was only the latest in a series of anti-Korean rallies in the neighborhood that have grown more intense in the past few months.

Often spearheaded by the rightwing group Zainichi Tokken wo Yurusanai Shimin no Kai (Zaitokukai), which translates literally as a citizens' group that won't tolerate special privileges for Korean and Chinese residents in Japan, these protests have raised eyebrows, especially for their blatant racism and outright death threats.
