Mount Tsurugi (剱岳 Tsurugi-dake?) is located in the eastern area of Toyama Prefecture, Japan. It is one of the tallest peak in the Hida Mountains at 2,999 m (9,839 ft). It is one of the 100 Famous Japanese Mountains, and is called "the most dangerous mountain" climbable.
Tsurugi has a number of routes which approach World class long routes. It is recognised in Japan as "the" premiere mountaineering peak in winter. Although dangerous, its death toll is a small fraction of those who have died on Japan's much smaller, but more lethal Tanigawa-dake.
