“Sometimes history comes alive in unexpected ways. In August 2026, a controversy surrounding Korean actress Ha Young turned a decades-old question about Japanese colonial collaboration into a national conversation about something much more personal: What happens when you discover that someone in your own family may have collaborated with Japan?”
The controversy began after attention focused on Ha Young's great-grandfather, Ahn Sang-ho, following comments she had made about her family's medical background on national television. Historical records concerning his activities during the Japanese colonial period subsequently became the subject of intense public scrutiny.
What followed was much bigger than one actress. Koreans across the peninsula and the global diaspora began asking:
- Who were our ancestors during the colonial period?
- Could someone in my own family have been a collaborator?
1. The “Pro-Japanese Ancestor Scanner”
One of the strangest manifestations of the controversy was the emergence of an online tool known as the Pro-Japanese Collaborator Scanner.
The website allows users to search surnames and bon-gwan (本貫)—the ancestral clan origin traditionally associated with Korean family identity—to determine whether individuals from that lineage appear in historical records identifying pro-Japanese collaborators or independence activists.
The site reportedly draws from official government historical databases, including records concerning recognized independence patriots and the Presidential Committee for the Inspection of Collaborations to the Japanese Imperialism's list of 1,006 collaborators.
Genealogical Fact vs. Assumption of Guilt
The scanner website itself warns users against assuming guilt by association. That warning is crucial. Because a surname is not a blood test. And a bon-gwan is not proof that two people are directly descended from one another. Korean genealogy can tell us extraordinary things about family history, but it must be used carefully and responsibly.
2. Why Koreans Care So Much About Lineage
For much of Korean history, family lineage was not merely a personal matter—it was social identity.
Korean families preserved jokbo (族譜)—genealogical records documenting generations of ancestors, marriages, academic achievements, civil offices, and family relationships. The ancestral clan, or bon-gwan, became an essential foundation of identifying one's lineage.
So when a modern Korean discovers that someone sharing the same surname and ancestral origin appears in a colonial-era record, the question can feel surprisingly personal. This is especially true when the historical figure was wealthy or prominent. And that is precisely what makes the current controversy so explosive.
3. Descendants Are Not Their Ancestors
There is a line that should not be crossed.
- A person born in 2000 did not collaborate with Imperial Japan.
- A person born in 1980 did not collaborate with Imperial Japan.
- A person born in 1950 did not collaborate with Imperial Japan.
Their great-grandfather might have. That is a historical fact about the family. It is not a personal crime committed by the descendant.
This distinction seems obvious when stated plainly, yet it becomes much harder to maintain when emotions run high. Recent commentary surrounding the Ha Young controversy has exposed exactly this problem. Some argue that the families of collaborators benefited from their ancestors' actions and therefore should not be allowed to erase that history. Others argue that attacking descendants amounts to collective punishment (yeonjwaje) and contradicts basic principles of justice.
Both concerns deserve serious consideration.
4. The Real Issue Is Not Blood: It Is Benefit
There is an important distinction between saying:
“Your great-grandfather was a collaborator.”
and saying:
“Your family currently owns property that was acquired through his collaboration.”
Those are not the same accusation. The first concerns ancestry. The second concerns an identifiable historical benefit.
And that distinction is at the heart of South Korea's renewed effort to recover collaborator assets. If the government can demonstrate that particular land or wealth was acquired through collaboration with the colonial regime, the question becomes one of legal restitution. If there is no such connection, simply being related to a collaborator should not be enough. That is why due process and historical precision matter.
5. The Danger of Turning History into a Purity Test
There is another danger here. If Korea begins treating ancestry as a measure of moral worth, the country risks creating a never-ending hierarchy of “good families” and “bad families.” That would be deeply destructive.
Colonial Korea was profoundly complicated. People made decisions under severe coercion, economic pressure, ambition, fear, and ideology:
- Some actively resisted at the cost of their lives and fortunes.
- Some actively collaborated for power and commercial advantage.
- Some did both at different points in their lives.
- Many simply struggled to survive and feed their children.
History rarely fits neatly into the categories that social media prefers. The goal of historical scholarship should therefore be to establish what happened, not to create hereditary castes of virtue and shame.
6. What Should a Descendant Do?
If a Korean or member of the Korean diaspora discovers that an ancestor collaborated with Imperial Japan, a constructive approach is essential:
Principles for Engaging with Complex Family History:
- Learn the facts: Read primary archival records and understand what the person actually did in context.
- Avoid reflexivity: Do not automatically defend the ancestor out of pride, nor automatically condemn yourself.
- Reject mob judgment: Do not allow strangers on the internet to define your moral identity based on events generations before your birth.
You are not responsible for the decisions of your ancestors. But you are responsible for what you do with the truth once you know it.
That is perhaps the healthiest way for the Korean diaspora to approach this entire issue. We do not need inherited shame. We need historical literacy.
And perhaps that is the unexpected positive consequence of this controversy: millions of Koreans who had never thought deeply about the colonial period are suddenly asking questions about their grandparents, great-grandparents, and family histories. That may be uncomfortable. But sometimes discomfort is how history is truly remembered and understood.
