Yasuko Namba – Wikipedia

Yasuko Namba (難波 康子, Nanba Yasuko, February 2, 1949 – May 11, 1996) was the second Japanese woman (after Junko Tabei) to reach all of the Seven Summits. Namba worked as a businesswoman for Federal Express in Japan, but her hobby of mountaineering took her all over the world. She first summitted Kilimanjaro on New Year’s Day in 1982, and summitted Aconcagua exactly two years later.
