Korea's Greatest Treasure Hunt: The $450B WWII Gold Mystery

One man dug a hole seven stories deep into the earth beneath a riverside field in Gongju, South Chungcheong Province. When the ground gave way and the excavator operator died in the collapse, investigators found his motive: a treasure map. And behind the treasure map, a legend that has haunted the Korean peninsula for more than eighty years — the myth of Yamashita's Gold.

SBS's beloved documentary storytelling show 꼬리에 꼬리를 무는 그날 이야기 (Kkokkomu) explored the full, extraordinary history of this obsession in its 220th episode on April 16, 2026. What the show uncovered was something stranger and more human than a simple treasure story: a decades-long saga of greed, belief, elaborate fraud, and the peculiar magnetism of a mystery that has resisted resolution for generations.

The Legend of Yamashita's Gold

The story begins in the final months of World War II. Japanese General Yamashita Tomoyuki — commander of the "Golden Lily Operation" — had spent years directing the systematic looting of gold, silver, and treasures from Southeast Asian territories occupied by Imperial Japan. As Japan's defeat became inevitable, the story goes, enormous quantities of that stolen wealth were transported and hidden in various locations across the Asia-Pacific region before Yamashita was captured, tried, and executed as a war criminal.

In South Korea, the legend crystallized into something specific and almost impossibly compelling: 2,400 tons of gold, valued today at approximately 600 trillion Korean won — roughly equivalent to a full year of South Korea's national budget, or around $450 billion — supposedly buried somewhere beneath Korean soil. Specific locations circulated with increasing specificity over the decades: beneath the Geum River in Gongju, in the waters around Jungjukdo island off Busan, in the Munhyeon-dong district of Busan itself.

The episode's listeners — comedian Kim Jin-su, actor Kim Ki-bang, and actress Hong Ye-ji — listened with the kind of wide-eyed attention that the show's producers clearly hoped for. "At this point," Kim Jin-su said at one moment, "I genuinely believe there's gold under this country somewhere." Kim Ki-bang, after hearing that the finders would be entitled to 60 percent of any discovered treasure, immediately began rolling up his sleeves. "That's 360 trillion won. Mine."

The Men Who Spent Their Lives Searching

What gives the Yamashita Gold legend its particular power isn't the numbers. It's the people — and the Kkokkomu episode traced several of them in fascinating detail.

Park Su-ung, the personal barber to former South Korean President Park Chung-hee, obtained what he believed was a treasure map sometime in the 1980s. The map was detailed: it indicated the locations of 36 gold Buddha statues, 450 tons of gold ingots, and a series of underground storage facilities, supposedly cross-referenced with 1945 land purchase records from the Japanese colonial government's general headquarters. Park began excavating in 1988 — and kept at it for a decade. He found nothing.

After Park's efforts ended in failure, another figure stepped into the story. A man identified as Jung claimed to have precise knowledge of where the gold was buried. To attract investors, he stated that he had entered into a secret agreement with a former CIA official — a claim that proved enormously effective in generating confidence and capital. Hundreds of millions of won flowed in.

The climax came in 2002 when underwater cameras were deployed during a drilling operation and appeared to detect large sacks in an underground space. Excitement was immediate and intense. But when the bags were finally reached and opened, they contained stones — specifically, the same stones that Park Su-ung had excavated and dumped underground during his own decade of digging. The entire thing collapsed. Jung was convicted of investment fraud and sentenced to prison.

The Human Cost of Believing

The Gongju excavation accident — in which a worker died when an amateurish dig destabilized the surrounding ground — illustrated something that the Kkokkomu episode lingered on thoughtfully: how dangerous the Yamashita Gold legend had become for ordinary people who believed in it too deeply.

Hosts Jang Do-yeon, Jang Hyun-sung, and Jang Sung-gyu offered the listeners a space to process the strangeness of it all. What does it mean when a story about treasure becomes powerful enough to drive people to dig seven stories into the earth? When elaborate fictional frameworks — the presidential barber's map, the CIA connection — become vehicles for extracting money from people who desperately want to believe in the possibility of sudden transformation?

The show drew careful distinctions between the con artists who exploited the legend and the ordinary treasure hunters who simply found themselves unable to walk away from a possibility that felt — with each new detail, each apparently corroborating document — increasingly real. The cast's reactions moved in real time from delighted excitement to something more genuinely reflective, as the story of the gold resolved itself into a story about human desire.

"It's not really about the gold," one viewer observed in response to the episode. "It's about what people do when they think they're standing at the edge of everything changing."

Why Kkokkomu Keeps Getting This Right

The episode was the latest example of why 꼬꼬무 has built such a loyal following since its launch. The show's premise — three hosts each share an extraordinary true story one-on-one with a single guest "listener" in a low-key setting — strips away the artifice of most variety formats and replaces it with something that feels genuinely human: a conversation between people who are trying to understand something puzzling together.

The Yamashita Gold episode played to all of the show's strengths. The material is inherently cinematic — real treasure maps, real excavations, real fraud convictions, real deaths — but also genuinely ambiguous. The gold was never found. The story never reached a clean resolution. And that ambiguity, the show's format allows, is itself the point.

Korea's relationship with the Japanese colonial era remains deeply complex, and the Yamashita legend sits at the center of multiple kinds of historical pain: the memory of looting, the loss of cultural and material patrimony, and the lingering question of what might never be recovered. The show didn't try to resolve any of it. It presented it, honestly, as the unfinished business it is.

What the Gold Actually Is

The most honest answer that the Kkokkomu episode arrived at — and it was clearly the intended destination — is that the gold functions more as mythology than as historical fact. Historians and treasure hunting experts who have examined the evidence over the decades have generally concluded that while Japan absolutely did loot treasure throughout Asia during World War II, the specific claims around Yamashita's Korean buried gold don't hold up to serious scrutiny.

The treasure maps were never authenticated. The CIA-connected figures turned out to be fraudulent. The "golden lily operation" was a real historical event, but its spoils were largely dispersed or destroyed in the chaos of Japan's defeat — not systematically buried for future retrieval in colonial Korea.

But myths don't require factual basis to be powerful. The Yamashita Gold legend has survived every debunking, every fraud conviction, every excavation failure. It persists because it speaks to something real: the belief that somewhere under the ordinary surface of the world, something extraordinary is waiting. That someone, with enough determination and the right map, might find it.

Kim Ki-bang, sitting in the Kkokkomu studio, was still willing to grab a shovel. "I'm not ruling it out," he said, grinning. "Nobody has proved it doesn't exist." The studio laughed — and then went a little quiet, in the way that good stories make you go quiet, when you realize you feel something unexpected about something you thought you were just watching for fun.
