Mrs. B. G. Miller, a member of the Hollywood Protective Association, points to an anti-Japanese sign reading ‘removed Keep Moving - This is a White Man’s Neighborhood’, on her house on Tamarind Street, Hollywood, Los Angeles, May 1923. Other houses in the street have similar signs and are a response to Japanese Americans buying a property on the street in order to build a Japanese Presbyterian Church.
In middle school I knew a kid who said he still hated the Japanese for WW2. He also claimed to have hammered splinters under his own fingernails to ‘see what it was like’ but I doubt that.
