Are there any major problems caused by Kurds in Japan?

Especially the tweets of a person called Ishii Takaaki and those who took power from his tweets and started a smear campaign against Kurds with Japanese tweets, even though they are not Japanese, who just wanted to denigrate Kurds.

What exactly do you think about this problem?

Is there such a thing? If so, to what extent?

The Turkish channel 140Journos has a video on this subject. You can watch it on Youtube.(There is Japanese subtitles)
