South Korean actor Lee Yong-joo, known for his roles in the dramas "Princess Hours" and "Blue Tower," has died at 44. According to reports, Lee died of cardiac arrest on Saturday, Aug. 29.

A close friend announced Lee's death on social media. "We regretfully inform you that our friend Lee Yong-joo has passed away suddenly. The shocking news is hard to believe. We ask for your warm condolences as he begins his final journey," the friend wrote.

Career and notable roles

Lee was best known in South Korea for playing a clumsy rookie soldier in tvN's military sitcom "Blue Tower," which aired in 2013. He also appeared in the show's related projects.

For international K-drama fans, Lee was recognized for his appearance in the 2006 MBC romantic drama "Princess Hours," starring Yoon Eun-hye, Ju Ji-hoon, Kim Jeong-hoon and Song Ji-hyo. Lee played Jang Kyung, a high school friend of Crown Prince Lee Shin, portrayed by Ju Ji-hoon.

Lee began his career as a fashion model before moving into acting. He made his screen debut in the 2004 film "Doma Ahn Jung-geun" and later appeared in television productions including "Hello, Franceska" and "Rude Miss Young-ae," as well as the 2022 drama "New Recruit."

Health and military service

Lee's death brought renewed attention to his previously disclosed heart condition. In February, Lee appeared on fellow actor Lee Jong-hyuk's YouTube channel and spoke about being exempted from South Korea's mandatory military service because he had been diagnosed with hypertrophic cardiomyopathy, a condition in which the heart muscle becomes abnormally thick.

According to a report by Health Chosun, Lee had previously said that his mother had also been hospitalized with the condition and that he was told it could be hereditary.

Funeral arrangements

Lee's wake was held at Room 5 of Bundang Jesaeng Hospital Funeral Hall in Seongnam, Gyeonggi Province. His funeral procession was scheduled for 6:30 m. Monday, Aug. 31, with burial at the Seongnam City Funeral Culture Complex.

What was claimed, and who backed it

AI-extracted; can misattribute a claim — see Methodology.

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status is Contested when two claims on this page negate each other; otherwise it counts the distinct outlets we found asserting it — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
