In Japan, right-wing extremists with support of officials in the ruling party call for persecution of Korean residents, and have launched a campaign of threats against journalists that cover Japan's war crimes.

The Korean residents of Japan are descendants of Koreans forcibly taken to work in Japan when Korea was under Japanese rule. Those alive today were born in Japan, but in Japan that does not give them citizenship.

Naturalization in Japan is not like naturalization in the US; it requires denying one's previous identity and trying to act totally Japanese. These people of Korean descent might be willing to get Japanese citizenship, but they don't want to deny their identity.
