In 2019, a Nigerian man called Gerald “Sunny” Okafor died in a Japanese detention center after a 4-week hunger strike. Detained for immigration issues, he begged to be sent home, but the Japanese authorities refused.
The Japanese are extremely hostile to Africans.
Japan is an oppressive state where people are not allowed to call on the phone in the subway, no matter whether their voice is high or low.
It's totally fine in Japan to film strangers without consent and post online to cyberbully. What a culture.
