Kirk here. My suspicions about the Kumamoto Keizai article I posted about earlier today have been confirmed. I found that the group that sponsored the event, which was identified as Kumamoto Wasamonkai (熊本わさもん会) in the article is actually written 熊本和桜紋会 in Chinese characters. And, if one searches for 熊本和桜紋会 one finds virulent anti-immigrant content such as what you see on the right, with all of the Japanese flags. It is advertising an anti-immigration event, sponsored by 熊本和桜紋会, that was held in Karashima Park and Shimotori Arcade on March 22nd of this year.
Another very curious thing is that the full name of Mr. Saeki is shown on the poster in pink. But, the Kumamoto Keizai article only published his family name, allowing him not to be identified by his full name (which would have made it easier for me to figure out who he is). I searched and found his Twitter account. Most of the posts were anti-immigrant.
Kumamoto Keizai, what were you thinking? You attended the event and saw the posters and still chose to publish an article that made it appear to be respectable.
Since this is a follow-up to my previous post, I'll end with that URL:
