After years of gradual public observations and incremental official assessments, South Korea’s top intelligence body has delivered its most definitive judgment to date on the North Korean succession: Kim Jong Un’s teenage daughter is being groomed to extend the Kim family’s dynastic rule into a fourth generation.
The confirmation came during a closed-door policy briefing to South Korea’s National Assembly on Monday, according to multiple lawmakers who attended the session. National Intelligence Service Director Lee Jong-seok told lawmakers that it is now reasonable to identify the girl, widely believed to be 13-year-old Kim Ju Ae, as the designated future leader of North Korea, lawmaker Lee Seong Kweun told reporters after the meeting.
This latest statement marks a clear escalation of the NIS’s public assessments of Kim Ju Ae’s status. Early in 2024, the agency first labeled her as the likely heir, and just months ago in February, it concluded she was nearing an official designation as successor. Monday’s briefing solidified that positioning into a clear, formal confirmation.
In a striking secondary finding that upends long-held outside assumptions about North Korea’s power structure, the NIS also dismissed the long-circulated narrative that Kim Jong Un’s sister, Kim Yo Jong, would pose a challenge to her niece’s rise. Citing unspecified but reliable intelligence, the agency told lawmakers Kim Yo Jong — long viewed by many foreign analysts as North Korea’s second-most powerful figure — holds no substantive governing authority, leaving her no pathway to block the younger Kim’s succession.
Kim Ju Ae first began appearing at high-profile state events alongside her father in late 2022, and North Korean state media has repeatedly referred to her as Kim Jong Un’s “most beloved” and “respected” child, a framing that sparked widespread international speculation about her future role. In recent months, she has taken on an increasingly public portfolio tied to the country’s powerful military: she has been photographed driving a tank during military drills supervised by her father and firing pistols during a visit to a light weapons factory. According to lawmakers who received the briefing, North Korean authorities arranged these public military appearances to establish Kim Ju Ae’s credentials among the country’s military elite and dampen existing skepticism about the prospect of a female leader.
North Korea has been ruled exclusively by male members of the Kim dynasty since the country’s founding in 1948. Kim Il Sung, the state’s founder, passed power to his son Kim Jong Il in 1994, who in turn transferred control to his son Kim Jong Un following his death in 2011. While the NIS’s assessment is the most definitive official foreign judgment on the succession to date, not all outside observers agree with the conclusion. Critics note that North Korea operates as an extremely patriarchal society, arguing that elite and public acceptance of a female leader remains unlikely. They also point out that Kim Jong Un is just 42 years old, and naming an heir so early in his rule could risk eroding his own hold on power, making a formal designation premature.
Details about Kim Ju Ae’s personal life remain tightly guarded by Pyongyang. North Korean state media has never confirmed her name or exact age; the widely used name Kim Ju Ae stems from a 2013 account by former NBA star Dennis Rodman, who met the Kim family during a visit to Pyongyang and recalled holding Kim Jong Un’s infant daughter.
