In 1975, the Japanese mountaineer, Junko Tabei, became the first woman to reach the summit of Mount Everest. As well as being an achievement in its own right, Tabei had to defy the cultural norms of a country where women were not expected to be world-class mountaineers. Louise Hidalgo talks to Setsuko Kitamura, who was on Tabei’s Everest climb, and to her friend and biographer, Yumiko Hiraki.
