Born in 1979, Hiraide became a serious mountain climber after joining a mountaineering club at his university. In 2001, Hiraide reached the eastern summit of Mt. Kula Kangri (7,381m) in Tibet. "Pursuing the unknown" in the Himalayas, his list of remarkable accomplishments includes first ascents, reaching summits without oxygen and skiing from mountain peaks. In 2009, he successfully scaled the previously unclimbed southeastern wall of Mt. Kamet (7,756m) in India, and with partner Kei Taniguchi, became the first Japanese to receive the '17th Piolet d'Or Award,' the "Academy Award" of mountaineering. He also received the 'Japan Sports Award,' sponsored by the Yomiuri Shinbun newspaper, in 2001 and 2009.
