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. She reached the summit of Denali on July 1, 1985, and the summit of Mount Elbrus on August 1, 1992. After summitting the Vinson Massif on December 29, 1993 and the Carstensz Pyramid on November 12, 1994, Namba's final summit to reach was Mount Everest. She signed on with Rob Hall's guiding company, Adventure Consultants, and reached the summit in May 1996, but died during her descent in the 1996 Mount Everest disaster.
