Mountain Ascended
Mount Tsurugi / Tsurugidake
Mount Tsurugi (Tsurugidake) is a fearsome 2,999-metre (9,839 ft) granite horn in the northern Hida Mountains of Toyama Prefecture, known as the most hazardous and technically challenging alpine peak in Japan. Revered in ancient esoteric Buddhism as a realm of hell forbidden to human feet, the mountain became the epicenter of an epic race in 1907 between the Imperial Land Survey team led by Yoshitaro Shibasaki and master hunter Chōjirō Uji, and the newly established Japanese Alpine Club. Upon reaching the virgin summit, the survey team made the astonishing discovery of an ancient Heian-period bronze cane head and sword tip, revealing that ascetic Shugendō pilgrims had scaled the perilous peak over a millennium earlier.
