Why do people who flock to South Korea look like Koreans?

The following is from the serial column of Masayuki Takayama, published in the weekly Shincho released yesterday, titled 'ridiculous.
People all over the world now know the correctness of my reputation that he is the one and only journalist in the post-war world.
In his opposite, Jun Matsuo from the Nagasaki newspaper mentioned in this chapter,
There are reporters from the Asahi Shimbun, in particular, Junko Takahashi, the second Matsui Yayori and more, and those who control the NHK news department and Arima, Kuwako, Takeda, and Ogoshi.
Ridiculous
The flag of Joseon has a yellow and white circle in the center of the crimson ground. A fine flag with black frills.
However, the current Korean flag has a red and blue circle in the center of the white background.
Misunderstood as Hinomaru.
If you hate Japan, you should use the Joseon-style or another design.
Still, in the style of Hinomaru, there is a longing for Japan somewhere.
Speaking of Yashiro Aki's style, the feelings of 'hate, miss' are mixed and cannot be cut off.
That's why 'Japan' appears somewhere in their behavior.
The total union of the labor union that is driving the current anti-Japanese fuss is also called 'Roso' in the Sōhyō style.
An 87-year-old older man always appears at the meeting and talks about it. The name is Gu yon choru.
According to 'The Truth of Gunkanjima' (produced by Yasuko Kato), Gu was born into an impoverished family in Gyeongsangnam-do.
His father moved to Japan and worked at Hashima (Gunkanjima).
He earned enough money to bring his family from Korea, and the 8-year-old Gu came to his father. 
No more worries about eating.
It went to school.
It was like heaven.
So it was different if I thought at the meeting that Gu would speak thanks to Japan.
He says.
'Korean people were scooping for food along the way to school.'
'Nakanoshima could be seen from the classroom window. Smoke stood on the wall of Koreans who died in the coal mine. The smoke increased every day.'
'On the day of the end of the war, the figure of the thousand Chinese who were brought from Manchuria disappeared. It was confined in a mine shaft and blasted the pit and buried it alive.
If the last trick were 'I can't even think of a brutal Korean,' it would still be plausible.
Anyway, Gu had lived warship island of hell for six years.
And he said that he had witnessed dozens and hundreds of brothers who have been abused and killed.
The audience whispered to each word, and eventually, the whisper changed to the anger of 'Beats the Japanese sumida.'
Gu just 'returned' to Gunkanjima, and the Nagasaki Shimbun faithfully translated the words of the hell witness.
But there was an objection to the article.
A classmate at the National School of Gunkanjima that Gu had attended, 'There were Li, Kim, and Zhang, but there was no Gu.'
'Nakanoshima is in the sea opposite the island from the school. It cannot be seen from the school window.'
'Gunkanjima was a highly modern city. Each had a dormitory and a canteen. There was also a residential area and a canteen for Koreans. There was no room to enter the island, such as a beggar.'
Incidentally, there was also brothel 'Yoshidaya' for Koreans.
Both managers and prostitutes were Koreans.
Gu's story does not agree with any of the resident's memories at the time.
He has been around for six years, but no one knows him.
His name is not in the school directory.
Also, the lie of 'Chinses burying alive' was included.
He is not ashamed to hurt deeply the hearts of those who think Gunkanjima is their hometown.
Nagasaki Newspaper Matsuo Jun Deputy Director, who wrote such a story of Gu, says, 'I think the story of Hajima people is also true. At the same time, I think there is truth in the story of the recruiter'.
Well, about Matsuo, do two truths to try to have it both ways, he took Gu.
He didn't look up the school directory or listen to the islanders at that time.
Journalist Matsuo spits out that it is to that extent good judgment.
There are similar people.
It is Daisuke Tsuda who was hired by Aichi Triennale for 8.6 million yen.
He spat out the comfort woman statue made with Woon Sung Kim couple of Korean sculptor as art.
He judged so, but the statue made a subject actually the event in which two female junior high school students were dead, being overridden with a U.S. army vehicle.
That's why she sits on a junior high school chair.
It was scolded to put it in front of the US military base, and it had been stored for a long time.
It was brought out later by a pinprick to the Japanese Embassy.
Now it has been renamed comfort women's girl statue. 
The comfort women story was initially a fake story of the Asahi Shimbun.
Besides, the statue is a diversion.
If how doing where does it become the art?
