  • Japan's Naoko Watanabe earns Guinness Record for three ascents of K2
  • Feat spanning six years, 2018, 2023 and 2024, now officially the most K2 summits by a woman Japanese mountaineer Naoko Watanabe has been officially awarded a Guinness World Record for the most ascents of K2 by a woman, with the certification now confirmed for a historic trilogy of climbs stretching from 2018 to 2024. The Guinness World Records certificate states: "The most ascents of K2 (8,611m; 28,251ft) by a woman is three and was achieved by Naoko Watanabe (Japan) who climbed the world's second highest mountain on 21 July 2018, 27 July 2023 and 28 July 2024." Watanabe's record was built across three separate expeditions. She first summited K2 in July 2018, returned to the peak in July 2023, and completed her historic third ascent on July 28, 2024, standing atop the 8,611-metre giant at approximately 9:00 am local time. With that final summit, she became the first woman in history to have scaled K2 three times, a feat now formally recognised by Guinness World Records. The 2024 climb was part of a Seven Summit Treks expedition. Chhang Dawa Sherpa, Expedition Director at Seven Summit Treks, confirmed her summit from base camp. A Japanese nurse by profession, Watanabe had already scaled 13 of the world's 14 peaks above 8,000 metres ahead of that ascent — a collection she completed in October 2024, becoming the first Japanese woman to finish all 14 and the first Japanese climber to summit six 8,000-metre peaks in a single year. Watanabe's final record-sealing summit was supported by a major rope-fixing operation involving multiple expedition teams. Seven Summit Treks played a central role, with Mingtemba Sherpa, himself reaching K2's summit for a fourth time, leading the rope-fixing effort from the Bottleneck to the summit. For Watanabe, the Guinness recognition of her K2 trilogy is the latest milestone in a mountaineering career that has quietly rewritten the record books.
