There are still mountains on this earth that no human being has ever stood on top of. Fewer every year, sure. But they exist. And every time a team sets out to change that, something elemental is at stake — the kind of thing that drew climbers to the mountains in the first place, long before permit fees and GPS trackers entered the picture.
In late April 2026, the seven-member Korean Alpine Federation team flew to Taplejung, Nepal, with exactly that in mind. Their target was Sato Peak, a 6,220-meter summit in the Kangchenjunga region that had resisted every previous attempt to climb it.
By May 4, three of them stood on its summit for the first time in recorded history.

What Is Sato Peak?
Sato Peak is located in the Janak Himal Range, northwest of Kangchenjunga, adjacent to the six peaks of the Sharphu group. It’s not a household name in mountaineering circles, and truthfully that’s part of what makes this story interesting. The peak is genuinely obscure — its altitude alone is contested across sources, ranging from 6,150 to 6,220 meters depending on who you ask. Its exact location has created real confusion over the decades, with previous climbing teams sometimes summiting the wrong peak entirely without realizing it.
The region was closed to climbers for decades, reopening only in 2022. Since then, there have been a handful of attempts specifically on Sato Peak. An Italian team reached a foresummit called Sato Pyramide at 6,100 meters in 2022. A Japanese team tried in 2023 and fell short. The Himalayan Database — the authoritative record-keeper for Himalayan ascents — had the peak listed as “unclimbed?” with a question mark, suspecting a Japanese team may have accidentally reached the top in the 1960s while believing they were on a different mountain altogether. Nobody knew for certain. Until now.
How the Climb Unfolded
The Korean team was led by Ahn Chi-young, one of Korea’s most experienced exploratory alpinists, alongside Lee Sang-guk and Lee Ui-jun on the summit push. The full seven-member squad flew to Taplejung in mid-April and were on the mountain until May 10.
The summit bid itself took five days.
They left base camp on a Tuesday, establishing Camp 1 below the east face before pushing to Camp 2 the following day.
A weather delay pinned them there for an extra day (that waiting game will be familiar to many mountaineers).
On day four, they pushed up to Camp 3.
On day five, a Saturday afternoon in early May, they topped out on the southeast face via a route that included technical sections on ice and mixed terrain.
They did the entire thing Alpine style, no Sherpa support, start to finish.
Why First Ascents Still Matter
Even though this isn’t the tallest mountain in the world, the first ascent is still important. It’s about going somewhere completely unknown, with no prior knowledge of the route, no one to call for beta, no record of what the upper mountain actually looks like up close. Every decision is made in the dark, in the most literal sense possible.
For mountaineers like Sonam Saxena, who understands firsthand the weight of standing somewhere extraordinary for the first time, the appeal is obvious.
Saxena has spoken about how the drive to summit Everest was fueled less by the mountain’s fame than by the personal challenge of pushing past what feels impossible. That same instinct is what sends a team of seven Korean climbers to a disputed, barely-documented peak in the Kangchenjunga region when they could have chosen something easier and better understood.
There are still unclimbed peaks out there. There are still lines no one has drawn. And somewhere, right now, a team is looking at a photograph of one of them and wondering if they could be the first.
