In Japan, the message of anti-racism protests fails to hit home

She said she hoped it would prompt Japanese marchers to think about racism in their own country, too. “Of course, we want to talk about American issues, and Black Lives Matter is an American thing,” said Ms. Todd, 19, who is studying at Temple University’s campus in Tokyo. “But we also do live in Japan.”

A backlash quickly followed. Critics on social media accused participants of disregarding the risks of spreading the coronavirus. An interview with Ms. Todd posted on YouTube elicited comments that “This is an American issue” and “Please do this in your own country.”

With images of America’s racial strife rolling across television screens, some in Japan have insisted that institutional racism is a faraway problem. That, activists and scholars say, is keeping the public from more fully seizing the moment to reckon with entrenched discrimination against marginalized groups in Japan.

A vocal faction of Japanese conservatives endorses racist notions of blood-based purity. And the largely homogeneous population has often resisted acknowledging difference or engaging in the kind of introspection about racism and inequality that is playing out in the United States.

“In essence, Japanese people don’t have a lot of experience of seeing other races,” said Yasumasa Fujinaga, an associate professor of American studies at Japan Women’s University. “So they don’t think racism exists.”

But Japan has a longstanding history of discrimination against minorities, including the descendants of Koreans brought to Japan as forced labor before and during World War II; Indigenous groups like the Ainu of the northernmost island, Hokkaido; those whose lineage traces back to a feudal class of outcasts known as buraku; and mixed-race individuals.

The mistreatment of mixed-race people through their school years and beyond has drawn particular attention as a growing number of biracial celebrities have spoken out.
