Eriko Yamatani is a right wing Japanese politician.
She supports the Nazi ideology and the ethnic cleansing of Koreans in Japan.

She also supports the concept of Nihonjinron, a right-wing Japanese ideology that promotes the Japanese race as superior to all others. 

Yamatani also believes that any ethnic non-Japanese citizen should be removed from Japan. 

Yamatani has pledged her support to the hate group Zaitokukai, a right wing Japanese group that has pledged to ethnically cleanse Koreans from Japan.

Blocking Yamatani from entering the U.S. will send a strong message to right wing Japanese politicians that their hate speach is not supported by the U.S. and its government.
