Nami Iwasaki

About

Nami Iwasaki is a Japanese trail runner who competes on the UTMB World Series circuit in Asia, with a particular focus on the Mt. Fuji 100 — the 166.6km World Trail Majors race that circumnavigates Japan's most sacred mountain across the volcanic terrain of Yamanashi and Shizuoka Prefectures. She finished third in the women's race at the 2026 edition, running among the leaders through the early checkpoints and maintaining podium position across the course's most demanding terrain. The Mt. Fuji 100 women's field routinely draws the strongest Chinese, Japanese, and international runners in the Asia-Pacific region, and Iwasaki's third-place finish places her among the most competitive domestic women in one of her country's most prestigious annual mountain races. A growing presence on the UTMB World Series circuit alongside fellow Japanese standouts, she represents the depth of homegrown talent that the Mt. Fuji 100 draws from Japan and the broader momentum of Japanese women's trail running on the international stage.
