I consider Junichi Kato, a Japanese YouTuber, to be a terribly racist person.
He has repeatedly made radical discriminatory remarks against blacks, women, and other groups for some time.
To date, he has not expressed any apology or remorse for those racist remarks.
On the contrary, he is a person who has publicly declared that he will continue to make such statements.

Here is the video evidence.↓

His influence is huge in Japan.
Therefore, letting such a discriminatory person go unchecked will encourage discrimination and prejudice against blacks and women in Japan.
We hope that you will raise a protest or statement based on the principles of anti-black discrimination and anti-women discrimination.
