The mother Kim Jong Un never mentions: Ko Yong Hui's Osaka birth and the secret that threatens North Korea's sacred bloodline myth

A silence of fifteen years

In the North Korean state, where the Kim family cult operates as a near-religion, one figure has been erased entirely. Since assuming power, Kim Jong Un has never once publicly mentioned his mother, Ko Yong Hui. State media avoids her image, and her photographs remain extremely rare. The regime's silence is not personal, analysts say, but political.

The mountain myth

North Korea's ruling dynasty draws its legitimacy from the so-called "Paektu bloodline", a carefully constructed narrative that ties the Kims to Mount Paektu on the Chinese border. In Korean mythology, the mountain is the birthplace of Dangun, the legendary founder of the first Korean kingdom. The state claims Kim Il Sung used it as a base against the Japanese, and that Kim Jong Il was born on its sacred slopes (historians place his birth in Russia). The entire ideology rests on an unbroken line of pure Korean heritage.

The woman from Osaka

Ko Yong Hui was born in 1952 in Osaka, Japan, to ethnic Korean parents who had moved there from the island of Jeju during the colonial occupation. When Ko was around ten, her family joined a large-scale repatriation program that brought roughly 93,000 Zainichi Koreans to North Korea between 1959 and 1984. She later became a dancer in the prestigious Mansudae art troupe, where she attracted the attention of Kim Jong Il. At the time, Kim Jong Il was already married to Kim Young Sook, a daughter of a senior military official chosen by his father, and was known to have other companions.

“The Paektu lineage is considered sacred. Therefore, the idea that the supreme leader is the son of a jjaepo is absolutely unthinkable.”

The stigma of the jjaepo

In North Korea's rigid social classification system, known as songbun, repatriated Koreans from Japan were branded as "jjaepo", a derogatory term for those suspected of being tainted by foreign, capitalist influences. They were placed under strict state surveillance and routinely barred from top universities and promising jobs. Ko Yong Hui's background as a jjaepo directly contradicts the narrative of hereditary purity. Acknowledging her openly would, in the words of experts, constitute an ideological shock to the system.

“Kim Jong Un became successor at 20 despite having achieved nothing. He became so solely because of his Paektu lineage.”

An unbroken silence

Ryu Hyun-woo, an exiled North Korean diplomat, noted in his book "Kim Jong Un's Secret Vault" that the current leader's sole qualification was his bloodline. Yet that bloodline, through his mother, leads not to the sacred slopes of Paektu but to a port city in Japan. The silence endures. For a regime that exalts purity above all else, the identity of the supreme leader's mother is more than a secret, it is a threat to the throne itself.
